    Synopsis: 
    A guide to features that distinguish the skulls of Neandertals

    The Neandertals were Late Pleistocene inhabitants of Europe, and their skeletal remains were among the first fossil humans that scientists recognized as representatives of an ancient human group. The name, “Neandertal” comes from the Neander valley in Germany, where a single partial skeleton was found in 1856. This name originally was spelled “Neanderthal” in written German of the late nineteenth century, and that spelling continues to be a correct alternative used in many scientific and popular publications. Lucky preservation and the great activity level of European archaeologists and pa- leontologists have left a substantial fossil record of the Neandertals, more so than in any other region of the world. The Neandertals persisted until after 30,000 years ago in Western Europe. Fossils with anatomical similarities to the European Neandertals have also been found in West and Central Asia, and are often called Neandertals themselves.

    It can be difficult or impossible to divide Neandertals from other people based on small fossil fragments. Instead of one single feature, usually a constellation of different features contribute to the identification of Neandertal fossils. Because there are so many Neandertal fossils, anthropologists have identified many different features that help to set them apart:

    At this station are some casts Neandertal skulls, in comparison with modern humans. Work at identifying the following features:

    • occipital bun
    • supraorbital torus
    • barrel-shaped vault
    • midfacial prognathism
    • high nasal angle

Neandertals

For years, I've worked on their bones. Now I'm working on their genes. Read more about the science studying these ancient people.

Denisova

From a finger bone of an ancient human came the record of a completely unexpected population. My lab is working on the science of the Denisova genome.

Acceleration

The advent of agriculture caused natural selection to speed up greatly in humans. We're uncovering some of the ways that populations have rapidly changed during the last 10,000 years.

Malapa

Just outside Johannesburg, the Malapa site is producing some of the most exciting finds in human evolution. This site is the headquarters of the Malapa Soft Tissue Project.
