I don't know you, haven't run across you before, hope I never do again, you sound like one of the reasons I stopped contributing to threads of this nature. No new information allowed, right? Nothing that doesn't fit with your mindset? All the science is settled, it was all dealt with by old white men, most of them from the clergy, a couple of hundred years ago.
Tread with caution all who enter here, closed minds are at work. The Principals of Geology was written by a man who never left europe, iirc. Charles Lyell (1797-1875)
Poor Darwin, didn't have the guts to write what he saw, in deference to Lyell.
But the truth of his observations of the geology of South America is in his Private Journals. I suggest you read what he had to say about what he saw - and the conclusions he reached, none of which you will find elsewhere.
PS. Don't bother to reply, I'm outa here. The insults aren't worth the aggro.
Could be but explain the "appearance" of the Andes to me for starters and I'll check your work to see how accurately it fits with what we actually see. Take all night if you'd like. I'm hitting the sack now so your essay will be due by, say, 10:00 CST tomorrow.
