Who Is Lucy?
Let's see what a popular high school biology textbook has to say:
"One early group of hominines, of the genus Australopithecus, lived about 4 million to about 1.5 million years ago. These hominines were bipedal apes, but their skeletons suggest that they probably spent at least some time in trees. ...
"The best-known of these species is Australopithecus afarensis, which lived roughly 4 million to 2.5 million years ago. The humanlike footprints in figure 26-17, about 3.6 million years old, were probably made by members of this species. A. afarensis fossils indicate the species had small brains, so the footprints show that hominines walked bipedally long before large brains evolved." (Miller & LeVine, Biology, 2010, page 768, emphasis as in the original)
We now need to ask a question we shouldn't have to ask, how much of this is fact and how much is fiction?
