MARS ATLAS NOW AVAILABLE
For the first time, an atlas of Mars is freely accessible. Compiled from images taken by the Mars Global Surveyor spacecraft, the atlas was put together by the California aerospace company Malin Space Science Systems, in conjunction with NASA. Previously, the best reference of this nature was a book put out by NASA in 1979, pieced together mainly from Viking orbiter images, and even some airbrushing to add detail. The technological advances of the intervening decades are evident in the new version, including pictures with a scale of resolution down to 250 meters.

As much as I hate to admit it, you meat eaters might be on to something. Or, at least you were back in the very beginnings of our
social evolution. A theory by a socio-cultural anthropologist, Michael Alvard, of Texas A& M University posits that social cooperation might have evolved out of a need to hunt for game. The benefits of banding together might have outweighted those of hunting alone even though the catch had to be shared. This early humanoid cooperation could have formed the base for social interactions today.
