Maybe that's true for the parts of the genome that do something. But it can't account for things like the shared error that prevents people, chimps, et al, from synthesizing ascorbic acid. The shared remains of viruses (ERVs) are another thing that is awkward for the anti-evolution activists. Were they deliberately inserted for some inscrutable purpose? Then why is it that if one is common to the two species of Asian apes (gibbon and orangutan) it is inevitably found in all African apes, including us? Why is it that if one is common to Old World monkeys and New World monkeys, it will also be found in all apes, including us?
The fact is, the precise pattern of genetic markers across species faithfully reflects the phylogenetic tress that had previously been constructed on anatomical, biogeograohic, etc, grounds.
OK - I don't have much background with ERV nor shared DNA errors but is it possible that these could be attributed to shared living conditions? Is their only one way for these shared errors and gentic markers to appear in DNA?
