Carl Zimmer puts the new mother-and-son fossils in
their place

In other words, the fossils Berger
discovered cannot be our direct ancestors. Instead, they may be
very informative cousins. If Berger’s right, then the evolution of
Homo happened in a surprisingly piecemeal way. Our legs got long,
for example, well before our arms got short.

As I predicted a few days ago, this is no missing link in even
the most banal sense of that phrase, but it’s a stunning find.
