Dr. Schwartz's research spans human evolutionary theory, dentofacial growth and development, and human skeletal analysis of recovered remains in the Mediterranean region. Most recently he has, with Ian Tattersall of the American Museum of Natural History, completed an analysis of virtually the entire human fossil record. He also recently headed a project involving the reconstruction of first United States president George Washington. Read more about the George Washington project at the link above.

In the evolutionary sciences, where we are all struggling to piece together a history that can be perceived only through the fragments of fossils or the living termini of a past that is now lost, it would be foolhardy to cling unreservedly to a particular set of models and hypotheses without at least occasionally questioning their very bases.

This is not to say that modern humans are not also obviously different from Neandertals in their own right - we know that we are unique. But, aside from pointing to the development of a chin, thinner bones, and a smaller face and smaller jaws, it wasn't until the early 1980s that an attempt was made to define uniqueness of modern humans without couching the discussion in terms of deriving modern human features from Neandertal or other "archaic" hominid features.
