@Ashwin_s and @Michael_Callen, you’ve both brought up important questions that are closely related. Broadly speaking your questions arise from the wide gap between how biology is explained by the “popularizers” and what current knowledge shows us.
@Ashwin_s to your credit you want to know what is really going on here. Let me help you out.
@Michael_Callen you are hitting a key confusion that can only be blamed on people misrepresenting manistream science to you. Darwinian evolution was falsified in the 1960s. We now know that nom Darwinian processes are more important for explaining DNA. This is well know in biology. This has nothing to do, also, with statements on God. Science is silent on God, the scientific understanding of Darwinism was falsified a long time ago regardless.
Both these themes come up in this article I wrote a a while back. How about read this and ask someone questions?
