Star Trek: Voyager -- Distant Origin

On the planet where Voyager's crew had previously been marooned, Professor Gegen and his assistant Veer, two paleontologists of a space-faring saurian species known as the Voth, discover the skeletal remains of a human, most likely Lt. Hogan. They are fascinated by the similarity of its genome to their own species, and Gegen suggests that this supports the highly controversial Distant Origin theory, that the Voth had originated on a far-distant planet instead of the current area of space from which they rule their empire. Proof of the theory has been sought by other Voth scientists, but the heretical theory has often led to their exile.
