Thank you for your logical presentation of things as you perceive them. I actually find that a bit easier to rationalize, being as I tend to believe we probably crawled out of Tethys and onto Pangea to start with.<quoted text>
So which came first, The Egg... The egg was a method a organism developed 100's of millions of years ago to deal with environmental conditions and one of those organisms, after 100's of millions of years, became a bird... Then after several 1000 years of Human Breeding some of those birds became Chickens as man acted as a natural selector....
Not to be confused of course, with things that transpired along the evolutionary pathways, a few mil years later!
Mess mess mess lol
