| > You wouldn't be able to tell the difference between a pine tree from 100,000 years ago to one today Perhaps. Certainly if you put me in front of the two trees I wouldn't be able to tell you which was which. But that's a different question than whether I can tell the difference. If you put me in front of a pine and a fir I couldn't tell you which was which, but it wouldn't be at all difficult to tell the difference. It might also be relevant that the last time I had any significant contact with any conifer was quite a few years ago. > it's called a continuous ecosystem because it remains very similar. Selective pressure would be very similar This is a myth. Specifically, it's the myth of the "living fossil". It's a popular concept, but not a scientific one. The majority of people can't tell the difference between a coral snake and a king snake. That's not evidence that coral snakes are similar to king snakes. > unlike the rare case of certain populations changing significantly when facing a very different situation Not relevant.

No, I mean you couldn't tell the difference, other than it being a different tree. If you had a bunch of trees from 100,000 years ago and a bunch from today, you would not be able to sort them.

Pick almost any life form. Grass, bird, fish, snake.

It's not that myth at all, and has nothing to do with it.
> Not relevant. It also isn't difficult to tell the difference between two populations that were divided by a barrier 100 years ago. Things drift.
The point is that there was no barrier. Most things don't drift very fast at all. Most species in an old ecosystem could have evolved more than a million years ago and had little change since then.
There are species that have existed for millions of years, you do accept that at least?
