Yep - saw a movie once where someone said monkeys developed shorter necks because it made it less likely for a broken neck to occur from a fall - IOW, the ones with longer necks had a higher mortality rate and shorter necks prevailed. That's what happens under Darwinism rather than a Blue whale and a termite springing from the same life form.
Yes. Darwinism explains MICRO-evolution, or changes within a species.
It has no bearing on MACRO-evolution, that apes, chimps, monkeys, and humans all came from a single ancestor. And, it’s easily (and reasonable) to understand why apes, chimps, monkeys and humans all have similar DNA components - that’s what God choose to work with, so that’s what’s in there.
