Paleontology is hot

Two important discoveries were made recently in Paleontology. Both are described in the lastest online issue of Nature. The first is all about the presence of the first tetrapod on earth : it seems they appeared 20 millions years before when we thought they had (400 millions and not 380 millions years before today). The second is about the discovery of a new human species, in Siberia, who share a common ancestor (homo erectus) with homo neandertalis and homo sapiens, and migrated before homo heidelbergensis, the ancestor of homo neandertalis, from Africa (between 300 000 and 500 000 years ago).

1) Tetrapod : an article in french (La Recherche) and a video on Nature.
2) New human species : Nature.

Both are really worth seeing and reading !
