The coelacanth species in the fossil record are absolutely extinct. What we found is another species in that order, the coelacanthiformes. The living species are pretty distantly related to the fossil coelacanths. They're just a lot more closely related to them than to anything else.

I also wonder about that whole statement about alligators being unchanged for millions of years when all we have access to are fossils. How do we know the soft tissue didn't change?
I mean, if we go by that, humans also acquired lots of mutations over the past 100000 years, so at what point are we considered a different species from the original human?

Wollemia nobilis have been thought to be extinct for 65 million years and in 1994, they found this plant hidden in Australia. There are only 100 plants left on earth, one being in a small park in Germany, so they might become extinct again.
There are only 100 adult Wollemi pines in the wild, but there are surely plenty more being grown elsewhere. I happened to come across one at the Babbacombe Model Village in Torquay, England, just a couple of months ago, and I've seen others at various Botanic Gardens (mostly in Australia, but still)
Wrong. Just like the coelacanth situation, Wollemia nobilis is a modern species of Araucariaceae which is not known from any fossil material. It's a rare member of a very ancient lineage but it was never thought to be extinct because it simply wasn't known to science prior to the discovery of living specimens. So it's absolutely not thought to be extinct for 65 millions years lmao
@@ShirinRose We have a wollemi pine in our backyard. They are very slow growers, which would explain the lack of adult trees, but you can buy young trees and it's not crazy expensive.

There's also "functionally extinct" where there are known individuals still alive, but so few that the species will never recover and the individuals no longer provide a meaningful ecosystem function, like the northern white rhino. Given the broad definition that "there is not enough genetic diversity in the population left for it to recover" this could actually expand the number of species to ones with quite high overall populations, but whose genetic capacity to repopulate, due to habitat destruction / isolation of breeding populations, means that without drastic human intervention, species like the koala could be considered functionally extinct.
Cheetahs have actually undergone a serve population bottleneck. The current population comes from very narrow bottleneck. One study looking at DNA analysis suggested this bottleneck was at one point 2 individuals... for 3 generations. Getting down to a single mating pair and recovering is just about as little genetic diversity as you can get and doing it for multiple generations in a row is even harder. So I'm not willing to accept the concept of "there is not enough genetic diversity in the population left for it to recover." If you have a single mating pair and both parents are viable, sure incest among the next generation might make a lot of 2nd generation have all sorts of defects.

@@MrARock001 The most conservative estimate used on the DNA studies show there was a population bottleneck. Further assuming random mating and negligible selection of the studied markers during that time would give a high certainty the modern population came from a mating pair. Worse, rather than being a mating pair for one generation, the next two generations were also reduced to a mating pair and that compounds the problem if you know how inbreeding works. I think we should relax those assumptions since no one mates randomly and whatever caused the bottleneck was likely excreting a selection pressure and it could have affected one of those markers. With more relaxed assumptions, we can conclude there was a bottleneck and it could have been as low as one mating pair, but it might not have been that bad. If we relax the criteria from "reduced to one mating pair" to "severe bottleneck" then it's not just cheetahs but many others which had recovered from such a state. As such, I don't really take the concept of a minimal level of genetic diversity to be viable all that much.

If there are 3M-100M undiscovered species, how many new species are appearing? This is also extremely hard to estimate because we would have to be somehow sure that a given specie wasn't present in the past.

There are species, such as the Lilliputian violet, which have been found only once, despite repeated search. Close behind is the Niumbaha bat (the name means "rare"), which has been found only five times, in places widely spread across Africa. How can we tell if these are extinct?
I don't think they're that much safer when we can't see them. For better or for worse, humans are a powerful species that can make huge impacts that we might not be able to see immediately.
Is it not possible to determine probabilites for missing species to be extinct ? In this case, we can estimate the real number of extinct species, even if we don't know exactly which one is extinct or missing.
Speaking of poor monitoring of species, I once looked up something I can across and it showed as being extinct, the Wikipedia listing has since updated but it still shows as possibly extinct, granted it is native to Jamaica and I’ve only seen it in mountainous areas

1:23 I remember back in college a professor told us that when aliens ask us how many species that are on Earth our answer will be like, “we don’t know & we will never know because we wiped so many out”.
On the other hand, we don't need to kedp track of all extinct species. Nor should we prevent all extinctions. We just have to keep our impact, that causes extinctions, to a minimum.
Great video but I'm confused. You make a point that there are so many species we have never even discovered yet so maybe the ones we haven't seen in years just need to be rediscovered.
At first i thought that by "more species should be extinct" you were saying that with all the catastrophic events that occured in Earth's past coupled with all the damage that human intervention has done today, way more species have managed to survive till today than one would think
What about some of those species where, as far as we know, there are only females or only males left? They're essentially 1 step behind extinction, so do researchers still hold back giving them the extinct status?
I'm a little late to this, but if a selacamp hasn't been seen for millions of years and it was presumed to be extinct, but was really alive still how does ICUN determine with no shred of a doubt that a species is extinct?
"... when the last individual of a race of living beings breathes no more, another heaven and another earth must pass before such a one can be again." ~William Beebe
I feel like these arguments only really allow for two rational outcomes. If we're worried about not being able to argue for continued protection of species we should just stop declaring _anything_ ever extinct, or we actually start declaring things we think are extinct as such until they aren't. The current system seems entirely unuseful.
I don't understand your reasoning. You say that if we care most about preservation of potentially non-extinct yet missing species, then we should stop declaring any species extinct, not just MIA ones. How does that follow? What good would it do to not declare extinct a species where there's "no reasonable doubt that the last individual of a species has died"?
@@somebodyelse9130 "No reasonable doubt" is completely arbitrary though. If we've ended up finding species actually alive after 100 years of not finding any of them, when are there actually no reasonable doubts? My argument is that these restrictions mean that the labeling seems entirely arbitrary and that if it's entirely arbitrary then the labeling is actively unhelpful.

1:10. FYI, pokemon are not real. 2:33. Coelacanth isn't a species. Its an order of fish with at least 90 species in the fossil record and 2 species alive today.
There was a spit-turning dog and it worked in pairs to turn a spit to power something that cooks food. on sunday it gets a break and works as a foot warmer in the church. But eventually the species died out when machines were invented.
As the history of life showed, species extinction isnt actually a bad thing. Its the norm. Just like death. The important part is that extinctions dont happen in to rapid a pattern. Otherwise it will drag the entire system, that both nature and we humans rely on, down. And while life will survive, We humans might not. So we have invested interest in keeping nature stable. Not frozen, not regressing or removed. But stable.
The issue is when actually Extinct organisms pull funds away from Critically Endangered Species, like what we have seen with the Ivory-billed Woodpecker.
1:42 "The IUCN only declares a species extinct when there's no reasonable doubt that the last individual of the species has died." That's nonsense. That would be a totally impractical standard. There's always the possibility that an individual or population of the species had been overlooked and will be found later. The IUCN is aware of this possibility and uses a different approach when to declare a species extinct. If a species hasn't been sighted in a certain timespan that corresponds with the generation length of the species, and a scientific expedition has been carried out looking for this species in the location where it most likely could have survived, and this expedition finds no evidence, then the species is declared extinct.
“Listed as Extinct because it has not been recorded since 1996, and extensive searches in the appropriate habitat, during the appropriate season within the known range, have failed to locate this species. Its disappearance has been attributed, at least in part, to chytridiomycosis-related declines.” Justification for the extinction of the Chiriqui Harlequin Frog.
How about a “presumed extinct” for animals not sighted in 50 years and there being reasonable evidence that this isnt just because theyre hard to spot? If this presumed extinct status persists for long enough maybe a species can then be declared extinct. The example of coelacanths also really doesnt work - its like emphasising the protection of habitats triceratops could live in because birds still exist. Sure, coelacanths still exist, but in many ways theyre nothing like the ancestral species, so trying to protect them using methods based off of the niches their ancestors filled wouldnt help.
One interesting fact:protecting the nature and animals it is a recent endevour,like from 1900 onwards with the major impuls after ww2.Until 1900 all the people,from common people to governement did not give a thought about protecting the nature.They killed,destroyed,poluate and consume everthing they could.Think only how the whales became a specie in danger.And this is as old as the human species.From neolithic peope to Rome and Greece,from India and China to South and North America civilizations,from Africa to Australia and Greenland,every civilization destroyed the nature without a care,worse then any modern day capitalist bc,compared to today,there was nobody who cared enough to try to stop them. So yes,we could do better but at least we try to do something compared to our ancestors.Nature park and reservations and protected animals are a modern idea.
Here’s a crazy idea; declare missing species extinct. If they turn up again, they automatically go into whatever the most critically endangered category exists at the time they reappear.
They are already accomplishing the same thing by listing them as critically endangered. Did you miss the part where she pointed out that listing these species *as extinct* creates apathy on our part, then we stop considering important environmental impact issues? I thought it silly at first as well, but I like the reasoning behind basically keeping animals listed as critically endangered forever. I am tired of people giving up on environmental issues, so we should *always* consider the environmental impact, or we could find ourselves the latest casualty on the list of the "critically endangered."
CORRECTIONS: When looking at the bottom of a stamp, the image you see is a *reflection* of the image that gets stamped. To stamp the word 'EXTINCT", what you'd see on the bottom of the stamp is the word, reversed. Wait, am I in the right place? Is this... where am I?
Maybe that shouldn’t be the only reason we’re keeping the planet somewhat clean it shouldn’t be just because oh this animal might be alive so it’s still the right thing
Just make a new label that means "appears to be extinct". We're never going to know if something is objectively extinct regardless of what we label it.
Sorry, I thought that this video was going to be about something more interesting like counterintuitive geological/biological processes that are slowing predicted extinction rates in unexpected ways. Instead, we get "We don't have the unlimited resources to track every species on the planet properly so our accounting is probably off."

bro only female mosquitos drink blood from humans the male mosquitos are actually necessary for plants to grow if we didn't have mosquitos we wouldn't have many plants either so yeah be thankful that you have mosquitos even though they might be annoying they still have a purpose
Probably they should have an extra category, like "presumed extinct", for such species
NatureServe's ranks of species endangerment has a "Persumed Extinct" rank rather than Red List's "Extinct" rank

A commenter said that they have seen an ivory-billed woodpecker 1 minute ago, from what i can remember.
The Blanco Blind Salamander hasn’t been seen for so long likely because it lives in a place that’s extremely hard to reach, in fact, there’s only a single confirmed sighting of them in their natural habitat
People tend to do the same with their hair. They refuse to admit that their gone. The fact of admitting alone has some kind of finality to it. And it can end all efforts to save them. So even when someone hasn't seen their hair for years, they don't like it being pointed out.
lol what
If there are 3M-100M undiscovered species, how many new species are appearing? This is also extremely hard to estimate because we would have to be somehow sure that a given specie wasn't present in the past.
Evolution doesn't happen fast enough, generally, for us to observe a new species forming in the time we've looked.
@@CAMSLAYER13 It's also quite a gradual process.
I love how so much of whether we declare a species extinct depends on how much hope we have in it still being alive 😂
"More Spieces Should Be Labeled As Exctinct"
If there's always a chance a member of an exctinct spieces is discovered, maybe we shouldn't mark any as definitely exctinct.
i meran then you can label them as not extinct again
the thing is
jsut lets say thers really just 100 induviduals of an extinct spec left but we say its extinct
then this spec can mostly live there in peace
if we label it as missing ppl wil lgo out and look for it searchign for it
disturbing it and in worse cases ruin its habitat with it
like humans can be super destructiv ,,,,even if they dont want to or have actually just good things in mind
in my area once an albatross showed up (im from central europe) so an albatross is a really rare sight
it stayed on a lake where a lot of other birds nest and rest
so many ppl rushed there to see this albatross that some birds there lost over 50 % of theyr nesting ground cause ppl would run around trampling eggs and chicks /nests into the ground without a care cause all they wantet is this "special" photo of this albatross
but all these ppl where "Naturelovers and Birdlovers"
Yeah, what if a T-rex is still out there somewhere on some undiscovered island.
There are species, such as the Lilliputian violet, which have been found only once, despite repeated search. Close behind is the Niumbaha bat (the name means "rare"), which has been found only five times, in places widely spread across Africa. How can we tell if these are extinct?
If it has been found only once, how do we know that it's not just a one-off mutation of something more common?
The Niumbaha bat is listed as least concern because it was sighted quite recently, it is just rare by nature.
"This list of extinct species is incomplete, you can help by expanding it!"
When there is a will there is a way and these species are fighting hard enough to stay hidden from us which is a good thing sadly
Just as you've said: if there's a will there's a way; We have to work harder to make them extinct then!
I don't think they're that much safer when we can't see them. For better or for worse, humans are a powerful species that can make huge impacts that we might not be able to see immediately.
Is it not possible to determine probabilites for missing species to be extinct ? In this case, we can estimate the real number of extinct species, even if we don't know exactly which one is extinct or missing.
Speaking of poor monitoring of species, I once looked up something I can across and it showed as being extinct, the Wikipedia listing has since updated but it still shows as possibly extinct, granted it is native to Jamaica and I’ve only seen it in mountainous areas
Which?
@ the galawas, this is how it’s pronounced, I’ll look up the spelling rea quick
@ galliwasp
__this list is incomplete, help Wikipedia expand this list__
I was expecting pun at the end, was highly disappointed… but I love the video regardless ❤😊
I mean, thats what happens when people who haven't scoured every single square inch of every part of the world to confirm such things are extinct so we just use hypothetical math to decide how many are going extinct every year.
1:23 I remember back in college a professor told us that when aliens ask us how many species that are on Earth our answer will be like, “we don’t know & we will never know because we wiped so many out”.
On the other hand, we don't need to kedp track of all extinct species.
Nor should we prevent all extinctions.
We just have to keep our impact, that causes extinctions, to a minimum.
This video was a roller coaster of emotion.
We have top men working on it right now.
Entertaining and informative as ever, thank you!
And then there's the fun concept of species re-evolving themselves to existence
We should know more about the endangered species also. Like give people hope to protect them even if there is a slim chance u know
Great video but I'm confused. You make a point that there are so many species we have never even discovered yet so maybe the ones we haven't seen in years just need to be rediscovered.
Love how the unknown species silhouettes have multiple pokemons in it.
I wonder how many of these species that haven't been seen in so long, have been seen by ordinary people who had no idea what they were looking at?
that's a very high probability
Dont think you can hide a Vulpix, Ekans, and Paras in the mystery species!
Wow few seconds ago and alredy reply
And Pikachu and Slowpoke
How do we know there are millions of possibly undiscovered species out there?
At first i thought that by "more species should be extinct" you were saying that with all the catastrophic events that occured in Earth's past coupled with all the damage that human intervention has done today, way more species have managed to survive till today than one would think
So what I'm hearing is that there are a lot of animals that should be in another category, *Presumed Extinct...but they might not be!" lol
I feel clickbaited by this title
Imagine their foyer plastered with missing posters saying: please call if you see any of these 210000 species alive
The number of potential species on earth is a massive overestimate. The largest possible number is likely around 5,000,000
What about some of those species where, as far as we know, there are only females or only males left? They're essentially 1 step behind extinction, so do researchers still hold back giving them the extinct status?
Not all species need both, and not all species we thought needed both actually did.
They're considered to be functionally extinct.
Whole world worrying about losing biodiversity and MinuteEarth is here making the bold claims in their video titles
You could list them as “Missing in Action”…
Oil miners seeing this: Way to go guys, lets shoot for 1000!
How has this not already had more views?
I'm a little late to this, but if a selacamp hasn't been seen for millions of years and it was presumed to be extinct, but was really alive still how does ICUN determine with no shred of a doubt that a species is extinct?
I grew up in the green swamp of Florida. I am pretty sure I have seen that woodpecker about decade ago.
Yeah that’s why disagree with Emily’s take here as many extinct creatures still have numerous reported sightings.
@@orangecat504non confirmed tho
@@americanmapper2445 yes I would say thiers a difference between reported and official sightings.

My new game while watching Minute Earth, spot as many as Pokémons as possible.
I feel like these arguments only really allow for two rational outcomes. If we're worried about not being able to argue for continued protection of species we should just stop declaring _anything_ ever extinct, or we actually start declaring things we think are extinct as such until they aren't. The current system seems entirely unuseful.
I don't understand your reasoning. You say that if we care most about preservation of potentially non-extinct yet missing species, then we should stop declaring any species extinct, not just MIA ones. How does that follow?
What good would it do to not declare extinct a species where there's "no reasonable doubt that the last individual of a species has died"?
@@somebodyelse9130 "No reasonable doubt" is completely arbitrary though. If we've ended up finding species actually alive after 100 years of not finding any of them, when are there actually no reasonable doubts?
My argument is that these restrictions mean that the labeling seems entirely arbitrary and that if it's entirely arbitrary then the labeling is actively unhelpful.
We should start with mosquitoes
Nah, ticks. Let's start with ticks.
How about the plasmodium that causes malaria? That’s pretty high on my list of species that could go extinct without being missed.

Mosquitos is a keystone species, can't remove 'em without screwing both a ton of plants and animals.
@@SioxerNikita "mosquitos is a keystone species" 🤓. Yeah, I don't care
1:10. FYI, pokemon are not real.
2:33. Coelacanth isn't a species. Its an order of fish with at least 90 species in the fossil record and 2 species alive today.
Fun fact: if mosquitoes went extinct there would be little to no negative effects on the ecosystem
There was a spit-turning dog and it worked in pairs to turn a spit to power something that cooks food. on sunday it gets a break and works as a foot warmer in the church. But eventually the species died out when machines were invented.
Who's that Pokemon.......time 1:10
1:12 they put every single pokemon here
I feel like the coelacanth one is quite misleading. The two current species are not the same as the fossilized ones of the Mesozoic.
As the history of life showed, species extinction isnt actually a bad thing.
Its the norm.
Just like death.
The important part is that extinctions dont happen in to rapid a pattern.
Otherwise it will drag the entire system, that both nature and we humans rely on, down.
And while life will survive,
We humans might not.
So we have invested interest in keeping nature stable.
Not frozen, not regressing or removed.
But stable.
The issue is when actually Extinct organisms pull funds away from Critically Endangered Species, like what we have seen with the Ivory-billed Woodpecker.
Be the change you want to see in this world
So my question is, how did they prove that those 900 and so animals and plants are extinct beyond a reasonable doubt?
Missing for 240 million years and found!?!?
Thats wild
1:42 "The IUCN only declares a species extinct when there's no reasonable doubt that the last individual of the species has died."
That's nonsense. That would be a totally impractical standard. There's always the possibility that an individual or population of the species had been overlooked and will be found later.
The IUCN is aware of this possibility and uses a different approach when to declare a species extinct. If a species hasn't been sighted in a certain timespan that corresponds with the generation length of the species, and a scientific expedition has been carried out looking for this species in the location where it most likely could have survived, and this expedition finds no evidence, then the species is declared extinct.
Which of those 902 confirmed recently extinct species would make the best pet?
So with the conclusion un mind, how did they reach the conclusion that the ones currently classic extinct should be so?
“Listed as Extinct because it has not been recorded since 1996, and extensive searches in the appropriate habitat, during the appropriate season within the known range, have failed to locate this species. Its disappearance has been attributed, at least in part, to chytridiomycosis-related declines.” Justification for the extinction of the Chiriqui Harlequin Frog.
So it is a quantum state of both extinction and non extinction until we observe it

Great video 😊
How about a “presumed extinct” for animals not sighted in 50 years and there being reasonable evidence that this isnt just because theyre hard to spot?
If this presumed extinct status persists for long enough maybe a species can then be declared extinct. The example of coelacanths also really doesnt work - its like emphasising the protection of habitats triceratops could live in because birds still exist. Sure, coelacanths still exist, but in many ways theyre nothing like the ancestral species, so trying to protect them using methods based off of the niches their ancestors filled wouldnt help.
Makes me so sad, Honestly.... 💔💔💔
One interesting fact:protecting the nature and animals it is a recent endevour,like from 1900 onwards with the major impuls after ww2.Until 1900 all the people,from common people to governement did not give a thought about protecting the nature.They killed,destroyed,poluate and consume everthing they could.Think only how the whales became a specie in danger.And this is as old as the human species.From neolithic peope to Rome and Greece,from India and China to South and North America civilizations,from Africa to Australia and Greenland,every civilization destroyed the nature without a care,worse then any modern day capitalist bc,compared to today,there was nobody who cared enough to try to stop them.
So yes,we could do better but at least we try to do something compared to our ancestors.Nature park and reservations and protected animals are a modern idea.
Most probably, what matters is which species are extinct by bad human activities. Other than that, it is natural selection.
3:30 "our amazing viewers"
You are right, we are as amazing as the fact you live inside our walls
There should be a tastiness scale to use to determine if something is extinct. If it tastes like chicken it isn't coming back
Okay, contents of the video not withstanding, that title is absolutely *metal*.
Here’s a crazy idea; declare missing species extinct. If they turn up again, they automatically go into whatever the most critically endangered category exists at the time they reappear.
They are already accomplishing the same thing by listing them as critically endangered. Did you miss the part where she pointed out that listing these species *as extinct* creates apathy on our part, then we stop considering important environmental impact issues?
I thought it silly at first as well, but I like the reasoning behind basically keeping animals listed as critically endangered forever. I am tired of people giving up on environmental issues, so we should *always* consider the environmental impact, or we could find ourselves the latest casualty on the list of the "critically endangered."

Maybe that shouldn’t be the only reason we’re keeping the planet somewhat clean it shouldn’t be just because oh this animal might be alive so it’s still the right thing
Just make a new label that means "appears to be extinct".
We're never going to know if something is objectively extinct regardless of what we label it.

Then thank you, IUCN, for not allowing for more environmental regulations to be canceled
Sorry, I thought that this video was going to be about something more interesting like counterintuitive geological/biological processes that are slowing predicted extinction rates in unexpected ways. Instead, we get "We don't have the unlimited resources to track every species on the planet properly so our accounting is probably off."
