I 'believe' in Evolution

[Brunitski]

Right, careful in that thinking, I agree. Because evolution is about variety, some species do better as individuals, and others do better as groups. But it only takes one offspring to spread your DNA. Humans can have one female who goes on to have 5 kids, then one of those kids goes on to have 1 kid who goes on to have 3 and so on and so on. So it only takes one, but usually the more you produce the better your chances to spread your DNA.

There is actually a minimum number of individuals a species must have if it is to survive. Below that and it is likely to become extinct. I thought it was as low as 1,000 but now it looks to be estimated at 5,000 or so.

That's a fascinating read Polaris, thanks.
