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.
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.
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.
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.
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.
Early mammals experienced pressures that generally favor a group during mass extinction, such as generalist lifestyles, smaller body sizes, and subterranean lifestyles
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.
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.
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.
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
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.
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 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.
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.
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
Marvelous presentation! Full of insights and tight science, but also presented to perfectly place our species in its global context. Keep writing and researching!!!
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?
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.
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 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!!!
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.
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.
I'm so sorry for the loss of your good friend. He appears to be very young and healthy, if I may... What happened? Perhaps you could make a video about him, sharing your memories/experiences with him, keeping him alive in our hearts and mind ya know?
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. Could hear every word, but it was a bit "muddy". Time for a mic upgrade. - Picture in Picture: Nice to see you, keep that! But sometimes your face was in the way. 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!

Very interesting! Well presented too. Wonder about the evolution of say the grasses in parallel with grass eaters as a system? And predators as well, is that a thing?
Exciting and brilliant presentation! Your enthusiasm carries the information forward. Whales Are amazing! I am confused by your use of the word "hooves" where the animals have toes and claws.
With lions and humans evolving together on the continent of Africa, I am quite certain that lions will persist nearby us. It's the little birds on little islands which fell to the predations of housecats that are to be mourned.
This is the most enlightening video I've seen in a long time. But I have a question: Can you not see during your presentation when your self-picture window has obscured what you are talking about?
57:10 - Everyone that can provide proper care for lions, leopards, cheetahs or whatever animal of choice should obtain some babies and raise them as breeding pets. The bond between the right pet and its competent owner is forever.
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.
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.
When I was building my adobe casa at 3450 meters altitude in the Peruvian Andes, I came upon what looked like choral. It was choral! Along with fossilized shells the size of footballs!!

And chickens are dinosaurs too.
Absolutely lovely. I just downloaded the book on audible to hear the whole story.
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.
I LOVED this omg. And I loved the punching of the table to underline how truly jawdropping all of this is
Incredible presentation! Your enthusiasm is palpable, and your attitude is so positive! Thanks you so much!

I've read both your books and found them engaging with adequate information to support your thesis.
This is a great lecture and so enthusiastically delivered. Thanks
It was a very good walkthrough of evolution and our history on this planet.
This video has made my whole day. Thank you for posting!
OMG this was better than the last jurassic park movies, no joke

Thanks and I'm almost completed with your book. I have enjoyed it as well as the first one.
This was such an amazing story. Thanks.
I read "The Rise and Fall of Dinosaurs" albeit in German. But it´s great - a really new sight of those amazing beings.
The R.i content deserves better audio quality
He's a brilliant writer. I look forward to reading his new book
52:59 i wonder if that is on purpose, but his camera placement is perfect
haha
This was a magnificent presentation, thank you.
Awesome lecture and fantastic book. read it more than once

2/3rds through your book... Love the story of the helicopter pilot in Aus... Great stuff!
I enjoyed your dinosaur book. Keep up the great work.
I've actually read the dinosaur book, who knew! Great book
Wonderful lecture!
Thank you.
Very interesting lecture. He's a really good speaker. Thanks!

I found this lecture extremely interesting and very well presented. Can't wait to get the books. Thank You! :)
A great and interesting presentation, thank you. Book purchased!

36:40: "Mommy, I want a pony! Actually, I'd rather have a horse the size of a miniature poodle."
Your narration seems to say that, in the Carboniferous, the earliest distinct ancestors of mammals split of from the existing line of reptiles.
If you are referring to 4:00, no he doesn't.
