Perhaps the most significant distinction between evolution and ID / creationism is evolution's ability to explain poor design features, e.g. male nip - ples, the recurrent laryngeal nerve, the presence / location of endogenous retroviruses, and (one of my personal favorites) the presence of a defunct gene for egg yolk protein in our placental mammal genomes.

Vestigial features, study of ebryonic development, biogeography, DNA sequencing, examining pseudogenes, study of endogenous retroviruses, labratory direct examination of natural selection in action in E-Coli bacteria, lactose intolerance in humans, the peppered moth's colour change in reaction to industrial pollution, radiotrophic fungi at Chernobyl all add to the modern evolutionary synthesis.
