I don't even know if it's necessary to "debunk" the OP because, well, it's not really a debate. It's like somebody saying "the sky is neon green." You don't really debate to prove him wrong; you simply point outside and say "no, actually it's blue."
So here's your "blue sky":
A few selected stages in hominid (macro)evolution from an intro bio textbook. Transitions galore. Even more transitions have been excluded for the sake of saving space. Excuse the scan quality.
Homologous structures in human, cat, whale, bat from the same textbook.
Alignment diagram for a gene found in numerous plants (thale cress, castor bean, corn, black cottonwood, barrel medic, grape vine, soybean, sorghum, asian rice, tomato, field mustard, moss, and others), parasites (plasmodium, the one that causes malaria), humans, and even in bacteria. The
macroevolution of the gene (and thus, species) can be traced by comparing similarities and differences between species. This has been done for literally thousands, perhaps tens or even hundreds of thousands of genes. Red means the most matches and black the fewest, and the length of the bar shows the sequence that aligned with the original gene. Each line is one species.
I'm all for letting PGers duke it out and hone their debating skills, but this isn't a debate.
