Ah ha, I see. Now we're getting somewhere (or about to go around in circles, I'm not sure yet). So it could just be a random mutation that became the next step in our evolutionary phase. I just wonder because most living organisms have defenses so that they don't become food. Why would evolution work against itself?
I think, strictly speaking, as long as a batch of DNA can survive and copy itself, it doesn't care how it's done. DNA doesn't look out for fellow DNA, hence competition through species. Tis' tribalism at the molecular scale
