Re: Did the Xindi all evolve on 1 planet?
I just watched the 3rd season opener "The Xindi". Archer obtains a body part from a Xindi-primate which Phlox compares against the corpse found in season 2's "The Expanse". He notes that DNA between the two specimens is nearly identical, even though the corpse was Xindi-reptilian, and agrees with Archer's suggestion comparing the difference as similar to that between modern humans and Neanderthals.
