Morphology and Diet:

Size and Scaling in Hominid Evolution

Stephen Jay Gould and David Pilbeam wrote a paper in 1974 that was shown ten years later to be so totally wrong in its conclusions that it has fallen into an obscurity not usually linked to either Gould or Pilbeam. However, they were actually right...

Why the Hobbits of Flores Were Probably Not Broken People

There is a new paper out suggesting that the Flores hominids, known as Hobbits, were "human endemic cretins." From the abstract of this paper: ... We hypothesize that these individuals are myxoedematous endemic (ME) cretins, part of an inland population of (mostly unaffected) Homo sapiens....

The Potato and Human Evolution

Fallback foods are the foods that an organism eats when it can't find the good stuff. It has been suggested that adaptive changes in fallback food strategies can leave a more distinct mark on the morphology of an organism, including in the fossil record,...

Life history trade-offs and human pygmies

Human Evolutionary Rate Study

There seems to be some interesting things going on with the recently reported study of rates of evolution in humans. We are getting reports of a wide range of rather startling conclusions being touted by the researchers who wrote this paper. These conclusions typically come...

Study Suggests Increased Rate of Human Adaptive Evolution

There is a new paper, just coming out in Proceedings of the National Academy of Sciences, that explores the idea that humans have undergone an increased rate of evolution over the last several tens of thousands of years....

Evolution of Birds: New Evidence for Foraging Behavior

New research published in Current Biology falsifies a widely held idea about the early evolution of birds.
