I cannot answer that question. Maybe God just used a common template and worked his way up?if evolution ISN'T true..........then explain the concordence between morphology based and DNA sequence based phylogenetic trees. Why would God have arranged for species higher up on a tree (as suggested by morphology) to have DNA changes that could be traced down the (DNA sequence based) tree to species theorised to evolve from species higher on the tree? Why the match? Why would God work so hard to make it LOOK as if species evolved from one another?
I will state this however, look at the alleged evolution of the whale's nostrils.
Shouldn't we have thousands of examples of the nostrils moving up the head as opposed to big jumps between one form and another?
