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?!
@@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
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!
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!
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
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…
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
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.
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 😍
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.
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.
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 :)
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.
As a New World Archaeologist, I have to jump in and say that this assertion that the megafauna were killed off by humans is extremely incorrect. This occurred during a period when a mass extinction was ongoing. It affected creatures that were not prey and were possibly unknown to any humans alive then. This extinction included marine animals as well. It occurred in all regions of the globe regardless of human presence. It occurred on a global scale, regardless of the almost certainly stark differences between human populations in terms of cultures and norms. It just wasn't humans. Sorry. I know that derails the narrative of many who want our species to be culpable because it provides a political club to swing in condemnation of humanity, but it is a fiction.
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
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.
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.
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.
@@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.
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.
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.
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.
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.
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! 🖖😊
(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.
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.
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.
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.
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.
@@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.
@@Userhfdryjjgddf 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.
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…
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.
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.
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.
The dinosaur extinction even has pretty decent evidence at this point that there was more than 1 impact zone. Perhaps Earth got hit with some debris from an impact in space
I think the more likely explanation for multiple impact sites is that the asteroid which hit earth broke into multiple fragments as it entered the Earth's Roche limit. This is basically what was observed when comet Shoemaker-Levy 9 impacted Jupiter. The comet was captured in orbit around Jupiter and broke apart as it made a close approach within the planet's Roche limit. The fragments continued on a highly eccentric orbit and impacted one after another as the planet's gravity pulled them back in, leaving impact sites in multiple locations due to Jupiter's rotation. en.wikipedia.org/wiki/Comet_Shoemaker%E2%80%93Levy_9
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. 🍄

After 66 million years the dinosaurs are still dominating this mammals podcast episode.
What a delightful episode! I do think that teeth are truly not given enough credit to our success as mammals! Well said!

Nice discussion.
Wow, Steve knows everything! 😂😂😂
Dr Brusatt needs to decaffeinate. After 10 minutes I had to call it quits.
Good episode like always.
And makes you wounder what John did in Ottawa IL?
Next time could you ask Steve his opinion on the Younger Drias Impact Hypothesis?
Hahaha, hey! Now I wanne know too, what have you done in Ottawa, Illinois?
The Blue whale is NOT the largest living creature, there are larger plants/fungi.

Can you picture a Bronte digging a hole or fitting into an existing cave?
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.
