Makes sense when you have a pre-existing theory to “ram” things into. Where are the links between?"..... I suppose you should have asked him whether he believed in the validity of paternity testing and DNA genealogic trees.
Why does this person look more like his biological parents, than he looks like his neighbor? Why does his biological parents look more like their biological parents?
Suppose you copy a string of DNA, then introduce a single mutation. Then you copy those two copies again, introduce a mutation more in each. Then do it again.
Isn't it rather obvious that, the more generations of copying and mutation that pass, the more different they become? Isn't it rather obvious that those copies with fewer changes separating them, have usually also had fewer generations separating them?
Why can creationists not reason out simple things like these?
