Editor's Note: This is Part 6 in a 10-part LiveScience series on the origin, evolution and future of the human species and the mysteries that remain to be solved. We are currently the only human species alive, but as recently as maybe 24,000 years ago another one walked the earth — the Neanderthals. These extinct humans were the closest relatives we had, and tantalizing new hints from researchers suggest that we might have been intimately close indeed.
The Many Mysteries of Neanderthals
Ardipithecus FAQ
Today is Ardipithecus day. Eleven papers in tomorrow’s issue of Science describe the research on one exceptional skeleton (numbered ARA-VP-6/500, nicknamed “Ardi”) as well as more than thirty other individuals, mostly represented by isolated teeth with a few partial sets of teeth. I have a lot of material to share about these papers and how they change things in paleoanthropology – so much that I can’t possibly fit it all into one post. So I’m starting out with a basic overview of the main points, organized as an FAQ.
Editor's Note: This is the last in a 10-part LiveScience series on the origin, evolution and future of the human species and the mysteries that remain to be solved. The past of human evolution is more and more coming to light as scientists uncover a trove of fossils and genetic knowledge. But where might the future of human evolution go? There are plenty of signs that humans are still evolving .

De l’'origine de demain
Dans un essai vulgarisé publié dans le Science de cette semaine intitulé "On the origin of Tomorrow" [1], Carl Zimmer se lance dans un exercice périlleux mais amusant de prospective évolutive humaine. Comme tous les animaux, l'homme évolue. Un chiffre simple et frappant pour commencer : un bébé, en naissant, porte en moyenne 130 nouvelles mutations génétiques par rapport à ses parents. La plupart de ces mutations génétiques n'ont aucun effet, et sont simplement transmises d'une génération à l'autre. Pour les autres, la sélection naturelle va s'exercer et leur transmission/fixation dans la population va dépendre des conditions environnementales. Mais cet environnement humain est aujourd'hui le résultat d'une évolution toute aussi importante : l'évolution de la culture et de la civilisation.
Humans Still Evolving as Our Brains Shrink | LiveScience
Editor's Note: This is Part 9 in a 10-part LiveScience series on the origin, evolution and future of the human species and the mysteries that remain to be solved. Evolution in humans is commonly thought to have essentially stopped in recent times. But there are plenty of examples that the human race is still evolving, including our brains, and there are even signs that our evolution may be accelerating.
