I'm wondering if someone can help me. I'm trying to find material on our pre-primate ancestors. From informal discussions I've heard that our line goes back through rodents, small lizards or a salamander type of reptile, through some long extinct amphibian and fish back to eels and sea worms of some kind. I know our full ancestral line has not been worked out, but I thought there might be some informed theories about this. It seems we are not descended from the most prestigious of lines.
