Resumen de Desperately seeking...: The chimp-human missing link
Barras determines the last common ancestor of humans and chimps. Comparing early hominin fossils, ape fossils and large numbers of living primates, Sergio Almecija thinks their forebear had hands and thigh bones that were more human-like than chimp-like. It probably still walked on all fours, he says, but not in the way that chimps do. Nathan Young and his colleagues have used a broadly similar approach to conclude the animal's shoulders were chimp-like--suggesting it swung through the trees like chimps do today.
