When Camels Roamed North America

  • Published on: 20 November 2018
  • Camels are famous for adaptations that have allowed them to flourish where most other large mammals would perish. But their story begins over 40 million years ago in North America, and in an environment you’d never expect: a rainforest.

    Hey, I want to clarify what we say about bactrian camels around 7:35. There are two different species of bactrians -- the so-called "wild bactrians" (camelus ferus), and "domestic bactrians" (camelus bactrianus). "Domestic bactrians" are descended from a species that is now extinct in the wild, and they are distinct from what we now called "wild bactrians". And the ancestor of domestic bactrians and what we call "wild bactrians" diverged 700,000 years ago, according to DNA evidence. So, they diverged BEFORE camelus bactrianus was ever domesticated. Domestication didn’t CAUSE the speciation, which is how some viewers were hearing what I said. I hope this clears things up. Sorry for the confusion! (BdeP)

    I have always wondered why do some types of camels have 2 humps and others have 1 humps

    It would be interesting to learn which modern species evolved from larger pleistocene fauna, and which species co-existed in the pleistocene with larger look-alike species that became extinct; e.g., did grizzlies coexist with short faced bears, or did they evolve from them? Did modern wolves coexist with dire wolves, or did they evolve from them? Etc., etc.

    Funny how 'camel' works for both camels and dromedaries in the english language. It's confusing to me to see that amalgamation of 2 species.

    you guys should hire the guys from bbc walking with dinosaurs special effects to do a full length modern prehistoric series. each of these topics could be an episode. you guys could keep the same narrators and narration style. something like that would be absolutely epic

    Did you know that Humans may have first domesticated dromedaries in Somalia and southern Arabia around 3,000 BC, and Bactrian camels in central Asia around 2,500 BC, as at Shahr-e Sukhteh (also known as the Burnt City), Iran.

    I think since I became unemployed two months ago I have learnt so much about evolution and paleontology that I am really beginning to understand it. Fortunately now I have a job!

    Can you do an episode with long sleeves, so your gesticulations are not just telling us, "I work out", and actually have some relevance to the subject matter you’re describing?

    Camels are cool. We here in Australia now have better camels to survive in the desert so that we export camels to the middle east.

    We also brought camels into the North American deserts during a war (cant remember which one) as they were more efficient at carrying supplies across it than horses, once the camels had outlived their usefulness they were set free on the desert, unlike in Australia though they didnt thrive and died out relatively quickly, sightings of "wild" camels became almost legend in small towns in places like Texas.
