Why We’re in the Age of Mammals with Steve Brusatte
Вставка
- Опубліковано 26 чер 2024
- We humans are the inheritors of a dynasty that has reigned over the planet for nearly 66 million years, through fiery cataclysm and ice ages: the mammals. Our lineage includes saber-toothed tigers, woolly mammoths, armadillos the size of a car, cave bears three times the weight of a grizzly, clever scurriers that outlasted Tyrannosaurus rex, and even other types of humans, like Neanderthals. Indeed humankind and many of the beloved fellow mammals we share the planet with today-lions, whales, dogs-represent only the few survivors of a sprawling and astonishing family tree that has been pruned by time and mass extinctions. How did we get here

What do you think Earth would be like if dinosaurs survived?
Be sure to check out Dr. Brusattes new book: www.harpercollins.com/products/the-rise-and-reign-of-the-mammals-steve-brusatte?variant=40073694543906

They did survive, they're called birds, with crocodiles and alligators being close relatives.
Bedrock? 🦖🦕
Dinosaurs survived, we call them birds.
Actually, the title got me thinking: the real question is why did birds survive? Mammals had nuclear refugia (we call them burrows) but birds? They typically live all exposed to falling meteoritic debris! How on earth and air did they survive?!
The reptilian humanoids would have reached and conquered Alfa Centaury by now..
I’m usually more about the space-y kind of stuff but I have to say that this was a fascinating listen. This channel never disappoints!
Glad you liked it!
This stuff is all important to understanding the fermi paradox
Got any good space channels to recommend?
@@dantheman4173
There's way too many choose from. I think the astronomy and planetary science channels of the highest quality include "Astrum," and "SEA," and "Kosmo,"
If you want long interviews like this channel, then definitely subscribe to "Fraser Cain" and the "SETI" channel. If you want another channel that covers fermi paradox issues, there is "SFIA with isaac Arthur" is good.
Personally I'm getting into this channel lately called "Highly Compelling" which focuses on human origins and Neanderthals
Have you heard of SEA Channel here on yt if you like space etc?
I love it when John asks questions that the interviewee loves. You can tell they are passionate and knowledgeable and JMG is just the guy to ask the right questions to get to the interesting stuff!
It always happens.
Didn't know Steve Brusatte had written a book on mammal evolution. I really enjoyed The Rise and Fall of the Dinosaurs, so I'll absolutely be checking this new book out soon!
The dinosaur episode is one of my favourite Event Horizon episodes. I hope there's plans for more content in this area.
There is !
Same
me too. this guy is just so good at talking
Which episode is that? Could you tell?
Yes! That was an awesome episode. Steve Brusatte’s enthusiasm is contagious.
Am in Edinburgh myself...tell the Prof I'll head up for some coffee and chat about teeth....haha. Great episode. New book is fantastic.
I'm living in Edinburgh too :)
@@reallyryan_ We should take a dander up the Pleasance and demand to be invited in for tea and dino chat...haha.
@@alexherbert9404 if you guys meet there, drink a coffee... Or a beer! For me. 😊
The professor is probably busy doing professor things
@@davidharrington4374 He's the one secretly cloning a mannoth.
This one is such a banger, already listened 5 times while falling asleep, intentionally of course. Think I finally got all the info consciously. Thanks homie
Love this channel. Has inspired me, educated me and helped me think outside the box. Thanks guys for all your hard work. Keep doing you !
After 66 million years the dinosaurs are still dominating this mammals podcast episode.
My absolute favorite podcast! Hi, John!
The best video that I have saw on this channel. 10/10.
Three minutes in and I can tell this’ll be a cracker- this Edinburgh prof. is super engaging and knows his onions.
Onions? I completely misunderstood the entire episode!
Thanks for all of the great videos with such interesting guests.
Wonderful episode. Love the editing that maximizes the substantive content. Great work.
Another great video featuring Steve! Thank you for making this happen.
Was not expecting to enjoy this episode/ topic so much. Fantastic.
I LOVED this episode!! Fascinating!! 💕 Thank u!!
thank you John and Steve!
What a delightful episode! I do think that teeth are truly not given enough credit to our success as mammals! Well said!
Let's gooo, gonna be a banger as usual! ❤️
What an amazing interview!! I must admit I wasn't thrilled by the title as it wasn't about space but it turned out to be my favourite ever episode!! ❤💕💕 Thank you so much John & Steve 😍
Hi, before even watching this week's episode I just want to emphasise how good the dinosaur episode was years back now. That episode got me hooked to this channel such a fascinating reveal of geological history a must watch
Wonderful episode. I especially liked the guest’s vivid description of the meteor impact and its aftermath. I felt as though I had witnessed it first hand, as a tiny shrew, and survived to evolve…
Must be because our ancestors lived it.
Thank you, so much!
Excellent interview! Thank you.
Great video and very interesting. Thanks for the episode.
Thank you, gentlemen........that was enlightening.
Just like before you even watch. Presume it’s gonna be great. You will not be let down 🌙 ☀️ ⭐️ 🦕 🛸
Wow! great a full hour!
Fav Channel on UA-cam and love this interview so just bought the book
Thanks Event Horizon for another Wonderful video! 🦕 🦖 🧬 🦣
Lovely episode. Enlightening.
THANK YOU
So excited
😍
The mammals triumphed because we're warm blooded.
Point blank period. Sure size was a factor, but it was the ability to warm ones own blood that got us thru that last mass extinction.
Thanks for your time, and the Future will be great again.
Great video !
If the climate continues to get warmer, i see mammals getting smaller and reptiles getting bigger.
I don't think it was a coincidence that the largest mammals in history thrived during the Ice Age and the largest reptiles (dinosaurs) thrived in a greenhouse climate. This makes sense when you consider that reptiles thrive on warm temperatures.
A very good explanation
The highlight of my fridays.
The science fiction videos can be fun, but the science videos are my favorite. Thanks!
This guy is an amazing speaker!
the teeth talk is great!
Nice discussion.
I saw a nature programme that suggested that out colour vision was to enhance our depth perception; because when your jumping from this branch to that branch you really don't want to misjudge how far away that branch is.
We aren’t really in the age of mammals. We are in the age of birds. There are many more species of birds than mammals, and birds are dinosaurs.
For some reason, we consider the age of x class of animals based on their size, I guess.
Otherwise it's probably the age of insects since some 300 million years ago
I'm always sceptical of the over hunting extinction theory. The human population was just not large enough.
Agreed.
I feel the class Aves is being short-changed here. The most advanced physiology on the planet, twice as many species with huge numbers of individuals,. Heck, parrots and crows are smarter than all but a very few mammals.
Lovely conversation & a delight to listen to.
I will definitely be keeping an eye out for the mammals book as a Christmas purchase :)
Only one wee thing which I know is just a technicality but thought worth mentioning, just that the referenced sabre toothed tigers weren't tigers but belonged to a separate cat family. Not a big deal but good to mention so people don't get them conflated :)
That’s cool you got Steve Buscemi on the show. I didn’t know Steve also wrote books.
Good episode like always.
And makes you wounder what John did in Ottawa IL?
Dimetrodon is my favorite Permian animal.
Perhaps an episode on the rise of Hominids and Humanity. Our evolutionary past/ancestral cousins, seems to be more diverse and meandering than we had ever guessed.
Not sure, but already at 2 minutes the guest made a very big mistake...(not implying he doesn't know it, just that he got carried away)
"The biggest thing that ever lived..."
Absolutely not. The biggest ANIMAL.
Arguably the Crocodilian adaptation to our planet and it's challenging environmental shifts, is the most successful animal form. For Millennia it has stood the test of time even successful today. You might argue the spider as well but that's from a strictly survival and still thriving today perspective.
incohesive
Interesting.
Please have Dr. Brusatte comeback to your show for an hour (minimum) freeform interview about animal teeth!
I just hope the Voth (Star Trek Voyager) don't watch this episode. They would say it's heresy against Doctrine! 😬
Fantastic interview, John! Thanks a bunch! 😃
Stay safe there with your family! 🖖😊
We're on our way out. 👋
Great episode as always John, Yeah the Tasmanian Tiger aka Thylacine was hunted to extinction by the europeans in the early days of Australian history. Many reports of people seeing them still pops up now and then but years ago someone posted a 1 Million dollar reward of proof but no one was able to claim the money.
Perhaps the only people capable of finding them aren't willing to reveal them for money?
@@gekkobear1650 I think a lot of the claims are real but misidentification, we do have some domestic dogs that have gone feral and there are still Dingoes in the wild. i would guess most people would take the 1 million cash for being able to prove they still exist.
@@alexgeorge2993 a lot of Indigenous people might not take the cash
What happens in Ottawa, IL stays in Ottawa, IL.
Wow, Steve knows everything! 😂😂😂
A three ton wombat would be close to unkillable. I hit a wombat at 60km/hour, I guess it would have weighed 30kg so 1% of a three ton monster, it rolled for about 20-25 meters, by the time I got out of the car it had dusted itself off and calmly trotted off (do wombats trot?) like nothing had happened.
Please like , comment and share. Quality content people !!
Hahaha, hey! Now I wanne know too, what have you done in Ottawa, Illinois?
1/ Mammals ate the last dinosaur eggs and babies that made it beyond the KT armageddon.
2/ Avian dinosaurs are alive and well and a chicken is almost exactly like a tiny T-rex.
No, the chicken is far diverged from T. rex.
(From a previous conversation I was in) The T-Rex in the BOOK was cloned with frog DNA filling in the gaps, supposed reason why it's eyes were bad. Badly translated to movie.
What's the size of house cat that dr Steve Brusatte referenced for the size of mammals at the time of dinosaurs, because some house cats can get to the size of small bobcats. Although i guess small bobcats would only be slightly bigger than the smallest dinosaurs so maybe my question is a bit moot. I just realized iv never actually looked up the meaning of moot, so im gonna do that real quick to make sure iv been using it correctly.
My ears are exhausted. So many explosive syllables.
I'm facing a long, gas free winter.* I'm happy to be a hairy mammal, and those few remaining lockdown kilos will come on handy!
*My house is 19th century, I have a fireplace so I'll get by.
Well looking at the inflation rate I mean... we can burn our money, too.
Being endothermic (warm blooded) means mammals have a broader range of climates they can live under, because their bodies have internal temperatures that do not change much. The internal temperatures of reptiles always matches those of their surroundings.
No, some reptiles, including most birds, are endothermic, and many are homeothermic too.
A book idea for doctor Brusatte: Teeth - Mammals Superpower. 😬
What have you done in Ottawa?
If we bring a mammoth back. It will be the loneliest mammoth in history.
27:00 Dinosaur intelligence: that's the big question.
Next time could you ask Steve his opinion on the Younger Drias Impact Hypothesis?
Warm blooded ground dwelling mammals had cold weather advantages over cold blooded dinosaurs. Maybe that is why they were able to sustain where the dinos could not.
There has been speculation that some dinosaurs were actually warm blooded.
👏👏
SO like... Megafauna. How big could mammals potentially get? Were the big bears, sloths, birds, and stuff. Were they maxed out in size? Or could they have gone bigger? Im guessing there is some optimal size where its beneficial to exist. In terms of surface area. Regulating heat, being fast and nimble, that sort of stuff. Maybe optimal size is that of a rat.
Ok but what did you do in Ottawa
I watch this to go to sleep
Imo It would be terrifying if dinos survived along with modern humans I'm sure we'd find a way to turn them into an attraction like Jurassic park 😅
I guess as the old saying goes, "What happens in Ottawa, IL stays in Ottawa, IL"
It's weird or perhaps not that crocodiles / snakes stayed pretty much the same but everything else evolved. maybe it's a mammal thing.
Naw.. they just have their act together….they don’t need to change … they are perfect for what they do…no need to adapt…plus unless they get hungry ,they are pretty lazy…
Regarding mammal teeth I recently went to a natural history museum and saw some fossils of a fanged one assuming it was carnivorous. But it was a trick it was actually vegetarian blew my mind.
Hippos and elephants are herbivores and they've both got some mean teeth. Boars too.
@@xjunkxyrdxdog89 boars will eat ANYTHING. baby deer and anything in their path. Yes they root primarily but still don't think boars can be in the same class as classic herbivores.
@@Immigrationsituation tbh I was basing that off my experience with veitnamese potbelly pigs. They're close to boar but not exactly the same. I guess that's one of the differences.
Wow...I'm 53 and only just learned today the dinosaurs were warm blooded🙄
well what have you done there 😱
Sooo... What happened in Ottawa?
"Noxious gases like carbon dioxide and water vapor" Does this guy know or understand the meaning of the word noxious? Carbon dioxide and water vapor are essential to life as we know it!
Next stop Ottawa, IL
Can you picture a Bronte digging a hole or fitting into an existing cave?
Wait I wanna know about the Ottawa il conversation. Thats where I grew up.
The Blue whale is NOT the largest living creature, there are larger plants/fungi.
Animal, not organism.
Warm bloodedness is a response to the the organism trying to live at a temperature that a fungus cannot. Humans live in a special temperature window and were pushed there by fungus. 🍄
Is there a better channel? I think not!
It took us about 6 million years to get us to where we’re at today…so how long would it take the dinosaurs to evolve in to the giants they became….
I think I know why you say 6my (cawc), but I'll ask anyway; why do you say that? And I'll you're wrong too.
Hey isn't this the guy you had on some years back that insulted the dinosaurs? I still remember that!
I feel like there is a mistake as biggest organism is actually fungi… specifically honey mushroom one in Oregon if I am not mistaken. Unless I miss understand something.
There's different categories for biggest, such as by volume, mass, surface area, etc. so it depends on which metric or category. This guy did misspeak as the blue whale is definitely not the biggest living thing, but definitely the biggest animal, as the only things that can dwarf if in other metrics are a fungus and an entire forest which is a single tree.
Some dinosaurs would likely be able to see more colors than us.
So in hypothetical alternative evolution there's a higher possibility that rather rats than lizards fly to the moon, yes-yes?
I have questions for people smarter than me... are there ways to have fire, or ways to smelt metals without oxygen?
Would an intelligent species that evolved on a planet with no oxygen in its atmosphere be capable of developing technology?
Sure. Fire is essentially just a chemical process called combustion -- so as long as you have a chemical for fuel and a chemical for oxidation then you can have combustion (and industry and technology). On Earth, oxygen is common, so it's the perfect oxidizer for us... on other worlds, chlorine, iodine, fluorine, or bromine could all be substitutes if oxygen is absent or in short supply. It's all going to depend on the chemistry of the world, of course.
@@olencone4005 I hadn't thought of oxidizing gases.... in my head all the oxygen would have been locked up in solids like metal oxides. Good call.
