When Camels Roamed North America

Loading...
  • 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)

    Do you not have enough distance between yourself & the camera that you would have to tuck in the elbows while gesturing?

    I remember going to a petting zoo in Nova Scotia Canada. They had a couple of camels. One was huge and it was a single hump. And he was bizarrely very friendly. He wanted petted all the time.

    Regardless of whether climate change exists or not, I am not commenting on it bc it is controversial.Since the deserts all over the world used to be rain forests. What if what we are experiencing on earth right now is actually the earth going through an intense heating period that will snap back into the largest ice age ever? We have evidence of ice ages followed by warming periods happening in the past. So how do we know climate change isn't just the earth heating up before an ice age...

    Well the thing of it is... there were humans in the Americas over 100,000 years ago. So we definitely ran into them way before 13,000 years ago.

    It is amazing how many large animals went extinct about the same time period, some 13,000 years ago and videos like this one have absolutely no information (8:57 on) about what Happened to them.

    In the 1800's, the U.S. Army imported camels as pack animals for the West. After the experiment, the survivors were turned loose and were sighted for decades after throughout the Southwest.

    You missed the camel's return to North America. Imported by Secretary of War Jefferson Davis )yes,that one) for military use in the Southwest. Didn't work out well and some were let go and there were wild, camels in Arizona for many years until the 20th Century.

    My grandmother found a fossilized camel jawbone in Florida in the 1930's. She donated it to the Smithsonian museum. She said they told her it was one of the first found in the US (I am not sure how true that is)

    It seems like camels in North America could have, would have, adapted to leafy coastal regions and the southeastern U.S. which is semi-tropical.
