The Oldest DNA Ever Found

Researchers mapped the mammoth family tree by extracting DNA from fossils. Also, scientists found some sessile animals living under Antarctica's ice shelf, and they're really cool.

Actually, I'm not super surprised to hear that Columbian Mammoths might be hybrids. I remember in one PBS Eons episode that scientists noted hybrids tend to be larger than their parent species.

You thought we wouldn't notice, but we did.

Anyone else get a notification before this called “delete this too”?

Teenage mammoth: "I'm sorry I said you're not my real mammoth."

Stepmammoth: nods forgivingly

Love how the first upload of this was "delete this too" from what I remember

I'm not curious about the delete this title. I'm curious about the "too" part. What else does Scishow delete that we don't know about?

Sub-shelf organisms: Wait!!! Where are you going? 😭

You forgot to mention that it was a geologist who found the organisms under the ice shelf, and that it was by complete accident. The geologist has such great luck, they found the only boulder on the sea floor in that area, for miles around.

Interesting, so the Columbian Mammoth is a hybrid species - hmmm.... - sounds a bit like Neanderthal / Denisovan / Homo Sapiens hybridisation .... :-) Maybe this is a lot more common in evolution that we might currently assume... - a population splits into groups that are separated by geography and time - then they re-converge giving rise to a new ?species/race/hybrid? that benefits through selecting the most suitable genes from both parent species... If you think about it that way, the hybrid ends up having evolved at double the speed of its parent species as it will have access to both their gene pools and, through natural selection, will choose and perpetuate their best innovations... - it is like splitting a problem into two pieces so that it can be run in parallel on two cpu cores/populations (and thus solved in half the time) before their answers are 'recombined' into the hybrid population.

Last time I was this early it was called delete this too
