>>12647005>Don't be a sheepIt's not being a sheep to learn the basics of a subject that you are directly asking about. I could have also said that you should study genetics, human physiology, cell biology, stem cell biology, and developmental biology. But the one field relevant to your question is evolution and it's not going to be a satisfying answer because your question is ill defined.
You don't go up to a mathematician and ask "why are squares not like circles?" then expect a satisfactory answer without grounding in the field.
You need to learn evolution before you can reject it. Otherwise you are just an ideologue.
