The Mystery Behind the Biggest Bears of All Time

Everything was big in Argentina.....

What about the man-bear-pig the most deadly bear in the world lol but i love your channel

Perky american science, needs serious adopting

Only 10 feet tall?? The bears in Kodiak island are 11 feet plus right now

Da. This chick is sexy, she has sum nice thick legs Mmmmmmm she so fine .

Why is ANY animal Or plant today going extinct? MAN.

MAN,MAN,MAN,MAN,MAN,MAN,MAN,MAN..Thats your answer to why they all went extinct.

She’s hot

The t-shirt is really weak honestly. Could have some cool dinosaurs and whatnot, maybe a stylized Anomalocaris.

lmao "and Steve" sounds like Steve is the guy at work no one likes

Btw, the "Ursus maritimus tyrannus" giant prehistoric polar bear sounds cool but probably never existed.The fossil was probably a brown bear.

Spectical bear is not plant eating. It is omnivorous.

Maybe it was humans that also hunted them. Idk?

Prehistoric animals are way more interesting than dinosaurs. They should make a version of Jurassic Park with them. Epoch Park?

would be better if a competent man was narrating

You could wear something better than those old looking jeans.

Yeah Steve!

That shirt is phucking hit

You look so cute in your new eons shirt !

They stuck long teeth on a modern lion!🤣

I have asked this before. If animals evolve along the same lines in different areas could be their DNA is more prone to say be wingless bird or big body. It’s DNA found it easier to go along the same lines since the original base dna was similar

Cali looks particularly shiny.

Payton, Butkis, Singletary, Urlacher, Dent, Bortz, Thayer, Krutz, Hampton, McMichals, Sayers....

What kind of music are you guys using in your Videos?Keep up the good work

Come on guys, fix that chromakey bleeding, it's not that hard.

Da 85' Super Bowl Champions, Da Chicago Bears?

IN BC's Queen Charlotte's a research team found a 7,500 year old brown bear lower mandible that is almost 18 inches long. That means if you're in a second story window the bear would be looking at you eyeball to eyeball. The mandible is now in the Victoria, BC Museum. The QC were grasslands then, not cedar treed like today. Bears love grass and eat LOTS of it. !!

Too bad it wasn't Hank Green hosting this episode; the puns would have been unbearable!

Maybe they were hunted by others, extinguished by humans competition, disease or any combination - the reason doesn't need to make "sense" always, it can be multiple simultaneous reasons

Could you put a video about giant panda evolution please? Thanks

WHAT??? They went extinct without people hunting them?

According to kamchatka native legends Arctodus Simus was there very recently, they called the creature "Irkuiem"

Ten thousands years ago, human is already a factor

I dislike that they put the animal's name behind the time stamp that appears when you pause the video.

She sexy

Such a pleasant voice....great content. Why did they disappear....it's ALWAYS climate change n the way that effects their food.

We killed em off just like the dire wolf

Very informative and well made! despite looking at the same pictures over and over again ;p

Too big...

A. sinus's legbones: they were weak for rapid changes of angle during high speed!!!!!!!!!!!!!!!!!!!! Not for long distance running. Please, be accurate :) And why did they die out? https://en.wikipedia.org/wiki/Younger_Dryas_impact_hypothesis
