Extinction and Survival
Hi Kaichos Man and since I don't think we've spoken before, welcome to EvC!
The problem for evolution lies in the fact that if I evolved from a microbe, then every one of my thousands of transitional ancestors must have played -and won- that game of chicken with extinction.
That's not quite right.
Extinction isn't something that happens to individuals, it's something that happens to populations, entire species or even larger groups. Whilst each of your ancestors must have won their battle to survive long enough to reproduce, there is absolutely no reason why we should assume that the species to which they belonged should have evaded extinction. An ancestral population could easily go extinct, leaving its derived daughter population, a slightly different species, to continue your ancestral line.
I am at a loss as to how this is supposed to be any kind of objection to the ToE.
