The fact that the pilgrims could live off the land supports the theory of common descent. Otherwise, if we crossed an ocean and encountered a whole new continent of "specially created" life, it should be expected that much of it would be totally inedible. Granted, this isn't "strong" support, but if things had turned out otherwise, it would be strong evidence against common descent.
Oh please. Such "evidence" would be widely disputed by today's Darwinists, lets not go there.
Instead, lets go for evidence that *won't* be disputed: code skipping.
Pick 3 species. Find genetic code that exists in what Evolutionary Theory would say have been in both an earlier and a modern species, but that skips entirely a species that Darwinists claim came in between the two.
Evolutionary Theory completely and totally breaks down in the face of genetic code skipping. DNA that skips an entire intermediate species falsifies Evolution...and it can't be argued otherwise by even the most rogue-ish and obstinate of Darwinists.
