"In and Out of Africa-the Horned Giants That Ate Our Ancestors"
Lecture by Chris Brochu, UI associate professor of geoscience. Recorded November 2012 at the University of Iowa Museum's Biosphere Discovery Hub.
The Department of Geoscience is a unit of the UI College of Liberal Arts and Sciences. Brochu specializes in vertebrate paleontology and phylogenetics, which are evolutionary relationships between organisms. His research combines the study of modern animals and the fossil record to demonstrate how evolutionary relationships can be determined through time. He is an expert in crocodiles and travels the world to research specimens in museum collections.

No chance to pay for college so thank God for these universities and colleges putting lectures up on RU-vid. It's what I live for, anything that has to do with life how it came to be where it's at and where it's going

@sforza209 Год назад

Your the perfect person for a tuition to attend any school cause you have the drive to learn!

Earlier in the talk I thought of the crocodile remains on Aldabra near the upsidedown jellyfish pool also near to where the sacred ibris hung out and the large fruit bats hung down from the bushes. Did he know about it? When you mentioned Aldabra I nearly jumped off my seat. Thanks for that mention brought back memories of 36 years ago. Thanks for the presentation I enjoyed it.

@christopherstube9473 6 лет назад

Very entertaining presentation , good story telling and good observations. Thanks, Christopher Brochu.

@kimberlynicole9955 2 года назад

This is exactly how someone comes across who is truly passionate about a certain topic & tries to share that enthusiasm with others who just don’t have the same basic understanding. It goes over people’s heads but it’s fascinating.

@MrAdryan1603 6 лет назад

Brilliant guy! Looks like the audience was really tired or didn't get his jokes, hahah. Very fascinating topic, glad to see people out there educating others on the more obscure, but nonetheless wonderful topics.

he specialises in the typology of crocodiles and their kin, if he makes some jokes i'm glad of them, and not expecting him to be devoting too much time on developing the skill.

Bit of a clickbait title, but it was interesting if a bit unstructured. Also the guy gets kind of obnoxious as soon as he starts talking about anything besides crocs. Why not include the questions?

Very cool. 1 thing I never understand is why does everything have to cross land bridges, swim or fly across oceans to be in an area. I'm pretty sure that rarely happened.

@smeggie42 6 лет назад

the camera work is killing me. stop zooming in and out on the guy and panning over just cause he switches the leg he standing on. just frame the screen with him in it and let him walk back and forth. its super distracting when trying to look at the pictures and it pans away and zooms in on the guy. other than that it was interesting

@ta192utube 5 лет назад

For an 82 cm skull to yield a 27 ft croc would require a 10::1 ratio, somewhat more than a 20% increase over the stated norm...still, loved the talk!

@kc3718 4 года назад

yeah, but it's cool ( cool = not scientifically valid ) and he defined cool with the vignette on the 'aquatic ape' nonsense. Keep up dude !

Study the crocodiles in Agusan marsh of the PHILIPPINES. The crocs group there are the biggest in the planet. We don't know why so much bigger than Africans or Australian crocs.

How the hell did they cross the Atlantic ocean?

@martink9701 5 лет назад

that's what I'm wondering

@Riceball01 5 лет назад

Depending on when we're talking about there may not have been much of an Atlantic Ocean to speak of. Don't forget, the Earth didn't always look the way it does now with continents where they are now.

@kc3718 4 года назад

Mid Atlantic Ridge creates new seabed and so the Atlantic isn't that old geologically speaking and thus was much smaller when they crossed. I think that movement/ seabed generation is just a few cm per year. If you look at South America and Africa the coastlines were once joined and also Scotland was joined to North America. A quick calculation which may not be accurate is that 6 million years ago the distance was 150km less or circa 100 miles...

@petermsiegel573 Год назад

As long as they ate them AFTER the subsequent ancestors were viable, it all would work out. Otherwise, you wouldn’t be here to watch the video.

@MrCountrycuz 4 года назад

The long nose evolved in a creature that needed to keep prey at a distance from its eyes as it held them underwater.

Great presentation. Horrible filming. Really bad. Camera-person: keep the dang slides on frame. Don't wander around with he presenter. He's not as important as the data on the screen, which you constantly abandoned to follow him around as he talked, waved his arms and POINTED AT THE SCREEN WE COULD NOT SEE! What was it that made you cue on his face and ignore the slide presentation? This was a fine lecture with horrifically frustrating camera coverage.

I’ve never seen someone fail at humor so many times in one speech that would’ve been just fine without any humor at all! I actually started to feel bad for the guy towards the end when he said something he obviously thought was hilarious and looked at the audience to share a good laugh only to hear crickets and awkward silence!

@jameslaforce8436 2 года назад

@youtoob4life 4 года назад

Clearly this guy didn't have the help of others when he put together this presentation, or they would've pointed out his poor sense of humor. Don't get me wrong, the information itself was wonderful and interesting, but man, his jokes just made me face-palm. Know your strengths man, humor isn't one of them.

@jeffbybee5207 4 года назад

His dismissal of the aquatic ape theory really proves what he said about knowing nothing about primates. Suggest he give elaine Morgan a listen. Read her scars of evolution . Think you. Would have a 50 50 chance of beleaving8
