There Was No First Human

If you traced your family tree back 185 million generations, you wouldn’t be looking at a human, a primate, or even a mammal. You’d be looking at a fish. So where along that line does the first human show up? The answer may surprise you.” (YouTube)

An interesting and amusing talk about evolution and how species gradually merge from one into another, with no clear point signalling the change. It’s like a previous video I’ve posted in which the ageing process is shown, but the changes are so gradual that you don’t notice them second by second.

Hurrah for fish. Onwards!
