The rise and reign of the mammals - with Steve Brusatte

[@iluvtacos1231]

Man, the enthusiasm he has is contagious

[@bigbadthesailor5173]

aside from loving the way the desk is banged in excitement, the simple, straightforward acknowledgement of students, collaborators, and native peoples is just great. thanks for a superb talk.

[@DungeonBricks]

Is charming seeing someone so invested in his lecture they start hitting the desk to bring a point home. That right there, is passion about a subjest, and I love it.

[@daniadejonghe4980]

Your description of the enormous richness and diversity of tiny mammals makes me think that the triassic and Cretaceous were a kind of laboratory/ workshop for the perfection of mammalian adaption... and that perhaps the very pressure of having to survive in the crevices, and having to do it for so long worked to the advantage of the mammalian class. So that when the dinosaurs disappeared the mammalians were ready and waiting to step into the light as it were.

[@elljorgo]

Nothing as changed... There were pressures then and there are still pressures now. Don't think that because there are no dinosaurs somehow it's paradise for mammals now. All are subject to their environmental pressures and will always be. That's how nature operates. Doesn't matter if 500 million years ago, 150 million years ago or now.

[@Rockzilla1122]

Early mammals experienced pressures that generally favor a group during mass extinction, such as generalist lifestyles, smaller body sizes, and subterranean lifestyles

[@maggiebrinkley4760]

Steve explains complex events so well for non-specialists - it's a real gift. I love his enthusiasm! His new book has gone straight onto the top of my Christmas list. Thanks, RI, for producing this fascinating lecture.

[@Myshcan]

Yes, he has a rare sense of narrative. If his books are like that, I'm sold.

[@randallwehler1186]

This is one of the best videos I have seen on the ascent of the mammals. I like the academic level at which it was presented. It all ties together so well. The narration has a clear and enthusiastic voice tone which keeps the viewer excited. Thanks for conveying a summation of findings since the late 60's when I completed a historical geology course taught by Dr. Robert E. Sloan at the University of Minnesota. Your presentation led to me reminiscing about my fossil hunts with my early deceased brother in the wilds of Wyoming and South Dakota. I retain those collections in a cherished way.

[@daytonturner2388]

I completely agree with you Randall. It's the kind of presentation I've been looking for for years.

[@psycotria]

Technically, extant lifeforms DESCENDED from their ancestors.

[@madedgar]

[@beth1072]

Absolutely lovely. I just downloaded the book on audible to hear the whole story.

[@mathewfines8727]

Incredible presentation! Your enthusiasm is palpable, and your attitude is so positive! Thanks you so much!

[@zoeydeu2261]

It's mind blowing that dinosaurs (our ancestors' predators) played a role in evolving our jaws, which became jaws that now eat the descendants of dinosaurs (chickens)! We went from rodent-like prey, to dominating the planet and being at the top of the food chain. Makes me wonder which class of animals will come next. Also humbles me when I see small rodents now

[@Dr.Ian-Plect]

And chickens are dinosaurs too.

[@kellyharrison5184]

Excellent and informative!

[@majamannhard443]

I LOVED this omg. And I loved the punching of the table to underline how truly jawdropping all of this is

[@dorcusmallorcus6450]

What a great presentation. Really interesting and well done.

[@chegeny]

Well-presented, informative lecture of the ascendency of mammals, with details not often discussed in other documentaries. The professor's passion brings palaeontology to life.

[@stephen_pfrimmer]

Thanks!

[@MrAjmay1]

So basically, the old narrative of dinosaurs had to be killed off by a mass extinction before mammals could rise, could be flipped to say, synapsid stem-mammals had to be killed off by an even worse mass extinction before dinosaurs could rise. There is balance in this. This is the way.

[@russellbrown7024]

I read this book - "The Rise and Riegn of the Mammals" - I loved it! It was a subject I had been interested in and this book was very thorough.

[@rasmusn.e.m1064]

I really appreciate the attention to providing perspective for the audience in this presentation. My favourite example is probably the pause to let us realise how wild it is that we are currently living alongside the biggest animal ever.

[@Sol-Invictus]

We are the only species in the planet's history to do what we do. Don't dismiss animal intelligence but it's pretty crazy what we are. I'd be willing to bet that life is everywhere in the universe. I just don't think what we do is common. Evolution doesn't have goals, it's just having surviving offspring. Earth had complex life with nervous systems for 600 million years. It could have gone on that way until the sun boiled off the atmosphere. We are our family (all life's forms) best, maybe only chance to live beyond the sun's life expectancy. As little as people want to accept it we might be the first technological civilization in the universe. And we can see how easily we may end that beginning. We are within centuries of expanding beyond earth. Within known physics we could have the whole galaxy in just 5,000,000 years, less time than our with our last common ancestor with chimps. All our history is an instant. We don't get the scale of time. Nations, cultures just a blip compared to our species and we are so resent compared to even ants or bats. Keep learning only knowledge lifts us above nature. Only knowledge can save us from brutal existence of our animal brethren... Only wisdom can protect us from creating that natural brutality within our grand civilization. We are a global super organism and that's pretty cool. A daunting prospect but still pretty cool.

[@johnrichardson7629]

I love these sorts of information intensive videos.

[@acanuck1679]

I have read both "The Rise and Reign of Mammals" and "The Rise and Fall of Dinosaurs". This presentation was a great corollary to the former--thank you.

[@thomasschwarz1973]

You mentioned 10 years was a long time in your life. Then the last 5000 years seems to be big deal for humans' development. But when we go back 50,000 years we diregard the changes that occur in 5000 years e.g. 65,000-60,000 years ago. Similarly it would be interesting to explore what might have changed over 5000 years 1,500,000 years ago. Can you help with that?

[@robertshelton9881]

I really enjoyed the presentation, and I learned a lot.

[@VIKASHSINGH-hf3kt]

what a remarkable session it was... i was lost in my mind about that lost world via his story about our ancient past. Thank you Steve Brusatte sir for sharing such a beautiful, tingling story with us

[@GoogleIsTooInvasive]

Greetings from Chicago! Thank you for all of your research and thank you for an excellent lecture!

Thanks for the excellent lecture. I read both of your books, they are very good indeed. Keep up the good work! Bob B

[@harveytheparaglidingchaser7039]

This is a great lecture and so enthusiastically delivered. Thanks

[@judith8161]

Thanks for distracting me from the ever changing, ever obnoxious symptoms of my current COVID infection. With all sorts of weird things going on in my body, I really need something to keep my mind off wondering what will be next. This is a fascinating topic, and honestly one I never quite thought about. Evolution to me is a miracle, though not one that I tend to explain with the existance of god. Nature in itself is mind blowing and overwhelmingly fantastic and beautiful, no need for a superior being to be in charge of all that ;-)

I've read both your books and found them engaging with adequate information to support your thesis.

[@AtmoStk]

A most excellent lecture! However, I have one small request. The image of the professor covers up the text which indicates the time period. I realize that it may be a feature of the slides, rendering it inconvenient to change. Regardless, have the time period's name and duration visible at all times is a very helpful context marker.

[@straighttalking2090]

Very interesting video which has helped me refine my understanding of evolution. Just one contention Steve if I may be so bold (will be honoured if you even read this!); You make it sound as though human beings are unique in developing consciousness 57:44 - now I am just a lay naturalist but I would say many mammals and birds display what appears to me to be "consciousness". I thought your narration was brilliant and made sincere by your obvious compasion. If you will forgive some nit picking the sound quality penetrated my consciousness here and there- you sounded like you were in a small wooden box which in a way was appropriate given the small box in the frame :) and the box itself obscured the text sometimes. Thanks for broadening my mind - shall be looking for more of your work.

[@stephaniehight2771]

I agree with you that there are many other species that have intelligence, consciousness and even culture on this earth. But humans are the only species on earth which provides evidence of culture that out lasts an individual's life. This ability to not only pass on knowledge from individual to individual, but to save the knowledge and learn collectively through language and writing is unique to humans. We are the first species to change the world through our collective, acquired knowledge. And even though we have learned so much, we have really been ignorant of the effects of our lasting effect on our world until less than 100 years ago. So, it is highly probable that we may be the cause of the seventh mass extinction. But it has been through an organism primal drive to do our very best to ensure, in each generation, that the next generation of our progeny will survive and prosper. Now we are about the third generation of h. Sapiens to have the knowledge of the scope of our effect on the world and other species in it. Talk about your geological or cosmological blink of an eye. We have been shaking the world for roughly 10,000 years. We've only been aware of our outsized effect for less than a century. And we're spoiled in the developed world. Pray that we are willing and able to counteract the havoc we have caused, but it was natural, because we used evolution's gift to cause it.

[@sundog486]

A great and interesting presentation, thank you. Book purchased!

[@mikesnyder1788]

I really enjoyed your book about dinosaurs so no doubt I will be reading your book about mammals. The Ashfall Fossil Beds in Nebraska are definitely worth a visit. My party of three traveled there a few years ago and the place is amazing. Very nice indoor facility and it is so cool to see college students at work as they discover all sorts of new fossils. Rhinos, people, rhinos!!!

Humans did not evolve consciousness or working in groups. These traits were present long before we showed up. Despite Brusatte's obvious expertise, he continually oversteps the boundaries of what we know.

I enjoyed this presentation, but I still don't understand the mechanism for the size demarcation between dinosaurs and mammals. Maybe I missed something and should watch it again.

[@psycotria]

After watching this video, along with another video presentation that detailed the descent of Mammalia from their basal form in the Carboniferous period, it seems that Dinosauria outcompeted Mammalia for most available niches, with only niches containing small Animalia having the "room" to accommodate both taxa.

Great video! I learned a lot and noticed I had some facts that needed updating 👍🏻 Here a few humble ideas of how to make it even better: - Audio quality.

Fade or relocate. - Video format: Good images and graphs. To look more up to date use widescreen format Thanks for sharing and keep up the good work 👍🏼 Subscribed!
