Best ResponseYou've already chosen the best response.0The 3 changes mean 3 "bifurcations" (branches) in the tree from their last common ancestor

Best ResponseYou've already chosen the best response.2yeah you could argue that the 3 changes in amino acids happened 3 splits/branches from the ancestor (one every split), or you could argue that they all happened at once, regardless, it doesn't tell you the similarities between the common ancestor and the descendants, so you don't know if one's hemoglobin mutated and the other didn't. But they would still be branching off the common ancestor. So to summarize node common ancestor (node), descendants (tips of branches).dw:1360181281410:dw
