These questions from Teno Groppi again are all variations of the same theme so I will deal with them in the same post:
Why would the amoeba even bother to evolve into "advanced" creatures like the dodo and dinosaurs that went extinct, when the amoeba is still around?
I claim to be descended from the Danish. This must be false because the Danish are still around. For that matter, my mother and father still are too. Just because a new taxon evolves does not mean that the parent taxon must go extinct! Furthermore biologists are not claiming that we are descendents of amoeba so this is a strawman.
How did life learn to reproduce itself, or even know there was a need to?
This question is incoherent.
With whom did the first cell capable of reproduction mate?
Reproduction predates "sex." Furthermore "sex" predates having two distinct sexes.
