ok, so If i have a baby which survives, thats natural selection taking place???
Your having a baby? Yes, that's natural selection taking place. It means your particular traits have kept you alive long enough in the struggle for existence (food, shelter, a mate) to produce a child and pass on the genes responsible for those traits.
That your baby survives? Is that natural selection taking place? Well, that depends on how long your baby survives. Once you are a grandmother the answer is 'yes'. Until then it's 'no'.
