Proofs of common descent that are pretty devastating to AIG, ICR’s, and Discovery Institute’s creationist arguments are the genetic histories of our species. In our genes you will find retrovirus strands in the same places you find them in our common ancestor species. With this data and these proofs the phylogenetic tree is being tuned by researchers and once enough full gene maps are compared we will know our full ancestry, and we will know it without any substantive doubts.
Science uses some of the SINEs and LINEs of our times to track our common ancestry, and determine some of what had to be true of your evolution and mine.
Our great national shame is that only Turkey has lower belief in the science of evolution than we do. We can not hope to maintain our lead in science, technology and to keep our pre-eminence as a world power if this ignorance continues far into this century.
