Jeffery,
There seems to be plenty of information and evidence on the development of TWO-GENDER reproduction. Worms are examples of both members of a mating pair are DOUBLE-gendered.
Vertebrates like fish only have differences internally.
Dinosaurs and other reptiles, as well as birds, have no specialized external anatomy.
It is when we reach into the millions of years of evolution in mammals that we start seeing lots of specialized external sexual apparatus.
But you know what, Jeffery, we all have our personal views of what is AMAZING… or TOO AMAZING.
You think sexual dimorphism is TOO amazing to consider a realistic evolutionary development. I think six day creation is WAY MORE “too amazing”. If we can’t agree on the age of the universe, there is NOTHING to agree upon.
