Does all land vertebrates come from the same ancestor? I found surprising that only one species were trying to colonize the land.
All tetrapods share a common ancestor but the land was already teeming with invertebrate life at the time. Take a look at this handy guide to see our lineage. :)
I think this was specific to tetrapods, though I don't know if there are any land vertebrates that aren't descendants of tetrapods.
