For anyone who really wants to know about this critter without all the media hype here's one of them scientific papers I threatened to dredge up. There's a lot of nasty scientific stuff but also some cool information.
Complete Primate Skeleton from the Middle Eocene of Messel in Germany: Morphology and Paleobiology From the section of the paper on locomotion we have this:
When Darwinius is projected into this PCA, as the juvenile it is (filled red circle) or as the adult it is projected to have become (open red circle), the result is virtually the same. Darwinius falls in the middle of both plots, near Callitrichidae in size, and overlapping Lemuridae and Cebidae in trunk and limb proportions. Thus Darwinius is interpreted as an arboreal quadruped specialized neither for slow climbing nor for leaping. Notharctus osbornianus (filled blue circle) is a larger North American contemporary of Darwinius masillae, but it occupies a similarly central position in the PCA.
and this:
After comparative study, we conclude that the Darwinius holotype was a juvenile female, weaned and feeding independently on fruit and leaves in the middle floor of early Middle Eocene rain forest of Messel. She may have been nocturnal. She moved as an agile, nail bearing arboreal quadruped and, although perhaps only 60 percent of adult weight at death (Fig. 12), would have grown to be the size of an adult female Hapalemur, in the range of 650–900 g. Her pattern of tooth development shows that her species grew up fairly quickly and suggests that she died before one year of age.
So the claims that the critter was basically a terrestrial biped are complete bollocks. Darwinius was not adapted to walk around on two legs.
Devious, treacherous, murderous, neanderthal, sub-human of the West.
