Again, the press are talking about “the missing link“. Let’s get one thing clear. There is no missing link. Rather, there are an indefinite number of missing branches. To have a missing link, you need to visualise evolution as a chain. If there’s a gap in the chain, then you have a missing link. But evolution, at least at the scale of animals and plants, is mostly a tree. And all we see are individual nodes of the tree, the extant species that form, in Darwin’s metaphor, the leaves of the living tree, and the extinct species that form branching points deeper in the tree. But we do not have enough information to know the shape of the tree for all but the smallest twigs and larger branches. There may be, for all we know, millions of missing species. We might have a species that is an ancestor of some other species, and yet not know enough to say that they are indeed the ancestor in question.
This looks to be an exciting find, and possibly it will give us more information about the overall relationships of primates, but it is not the missing link, and it is one of potentially millions of missing nodes of the evolutionary tree.
