Monsters We Met - Eternal Frontier pt. 2

When our early ancestors entered new lands they encountered a variety of strange new creatures,
monsters that no longer exist. What were they like and where are they now? What are the real answers
to the mystery of the missing megafauna?

100,000 years ago, Homo sapiens first ventured out of Africa.
The world they entered was the domain of giants: monstrous marsupials,
huge eagles, savage short-faced bears and the terrifying 5.5 metre long ripper lizard, Megalania.

These monsters now exist only in our imagination or as long dead bones in a museum.
In some areas of the world over 70% of large mammals became extinct around the time that
humans arrived on the continent. But why? Was it man's arrival or was it coincidence?

What are the real answers to the mystery of the missing megafauna?


Extinctions caused by humans In contrast, the extinctions at the end of the Pleistocene
seem to target large animals, with the small to medium ones escaping relatively lightly.
Scientists that support the overkill hypothesis believe that this evidence points to humans as the culprits.
The impact of human hunters on populations of large, slow-maturing, slow-breeding animals,
such as mammoths and diprotodons, was bound to be far greater than any effect they might have
had on small, rapidly breeding prey such as hares or squirrels.

Therefore, the overkill theory seems to explain why only the megafauna died out.

-Eternal Frontier-

North America - 13,000 years ago While the world was still in the grip of the last ice age, humans first crossed Siberia and entered the New World. They encountered creatures familiar to them from their travels, such as the woolly mammoth and the steppe bison, but also a whole host of new marvels. The Americas was the only continent where humans ever came face to face with sabre-toothed cats, giant ground sloths or the massive short-faced bears. As the climate warmed and the ice melted, all these megafaunal marvels vanished. What or who was responsible for their demise?

prehistoric people that were clean shaven and had straight clean teeth? lol

[smokeyj36]

Seriously though, why couldn't they just use the Walking With Beasts mammoths??

[FearedAudacity]

Only thing - the American Lion was not a true lion, its skull was built more like a tiger or jaguar. Other then that, and the fact the condors made the same noise as a golden eagle (lol) its an awesome vid.

[Transformers2935]

How do i thumbs up the new youtube look doesnt have the thumbs up feature any more.Help plz!!!!!!

[Transformers2935]

@smokeyj36 It would cost a fortune

@arash20d Are you a moron? Asian people can rarely grow full beards. Many can't grow any significant facial hair at all. Mostly just a light mustache at best.

[invisiblejaguar1]

I searched it up and it said it was a live action one. I didn't know that modern lions could survive in snow. It seems logical that they can though if raised up in that echo system.

[TheVelociraptor15]

@invisiblejaguar1 I know it's supposed to play an American lion. I just wanted to know if it was a live action or CGI one. Oh and it I can tell the lion's really there because lions CAN survive in the snow if raised in cold places. Perhaps she was a cub when she was taken to Britain and when she grew up she became an animal actor

[invisiblejaguar1]

It's a prehistoric American Lion, much bigger than the African Lion that we're familiar with in our modern time. But they've somehow used an African Lion to play the part of an American one. I don't know how they did it though, maybe they got footage of an African Lion and somehow cut it into a snowscape place.

actors much

@arash20d

search Google for YANOMAMI images. They are the most primitive people on Earth, not very different from these pre-historic people in this video. They are clean shaven and with straight clean teeth.

[rogerpenna]

@smilefromthestreets7

yes, but these are native americans, not aboriginals from Oceania.

find me photos of native americans with beards or mustaches.

EVEN if they grew beards, they already could shave. Look at the Yanomami tribe from the Amazon. They are the most primitive people on Earth. And guess what? They are clean shaved (or dont grow beards). And they have good teeth.
