I saw the wikipedia one, but it doesn't really give much info: the ancestors shown there looks similar to platypus, but doesn't answer much since the platypus is so much different from any other species.
Though I don't really like the egg-laying genes being called "avian", since it's from the dinosaur era. (and gives a false impression that it's actually related to the avian genetic track)
What I'm curious is what's the in-between from dinosaur to platypus like?
That's not implying the avian-like genes are actually avian. It's possible those genes lay dormant in early vertebrates (ancestors of both mammals and dinosaurs/birds) until selected upon when reproduction became more complicated. Covergent evolution and the like
