evolutionary chain

The diagram had me a bit confused at first - I guess I was looking at it geologically, with the progression being bottom (oldest) to top (youngest). I just want to clarifiy that the progression is from upper left to lower right.I haven't been following this topic real closely, but your diagram (IMO) is still a tree. I guess you could call it a branching chain.Would it be accurate to say that the various line junctions would represent the proverbial "missing links" (no chain pun intended)? A common ancestor to the species that came later?Moose

Gave the idea a POTM.I wonder if there's an example of such available on the web. Would be interesting to see.I don't think there's much of a photographic history for my personal ancestory. Especially since my father was orphened at a very young age.Moose
