I can’t comment on that idk what those questions are. The eye ball one I already shared the evidence for. I will add that Darwin came up with his theory a long time ago and he didn’t live long enough to expand on the new evidence that we’ve found. New fossils and dna gave us a clearer picture. Also a lot of his focus was on plants and how you could actively select for certain traits. Darwin talked about how breeders of plants and animals seem to understand evolution better because they’re seeing it in a simulated environment.
