If were all ape-decedents, who should I be more morally inclined towards men then animal?

Your question has nothing to do with evolution.

Us, like any other species on the planet that shows social behavior (bees, ants, bats, crows, dogs, wolves, apes, dolphins elephants, horses, penguins, mice ... you get the idea) are morally inclined towards the members of our own species and only then we consider the well being of other species.

This happens because, just like all the other animals on that list, we live in a social environment and it's in our best interest to care about the members of our own species first. We have to get along with the members of our "pack" and that's why we favor our own kind first.

And my opinion is that it's not justified to act morally responsible towards other apes like us and not as much towards dogs for example. I think we should treat all creatures with the same respect we show our own people.

BUT in a life and death situation, if I have to choose between the survival of a dog and the survival of a human, I would always choose the human first. BUT ONLY IF I"M NOT CAPABLE OF SAVING BOTH. Just like a wolf would always consider the survival of his own kind higher than the survival of a human.

Would you suggest that man is either vegetable or mineral?

Man is the unique rational moral agent and as such the only one capable of perceiving right from wrong conduct. Human rights differ from animal rights accordingly. A tiger can eat it's young with moral impunity, because it can not perceive moral actions as being right or wrong and therefore doesn't retain the same unique dignity man does... A man can not eat it's own young with moral impunity.

If you cannot grasp that you ARE an "animal" then intellectually, you may just be "already lost"...

You may have a point, though....your intellect perhaps more closely resembles that of a plant than that of an animal...

we are inclined towards man because of our thinking ability and the reasoning and the logic which the primates do not have.

Why should we be held morally accountable if our actions are determined by our genes and environment?

How did you manage to get a PhD with such atrocious writing?

You don't have the intellectual integrity to actually learn the answer.

Evolution obviously has you favoring your own species.

What does this question even mean?
