Research by John Hawks

I work on fossil and genetic evidence for human origins with collaborators all around the world.

Research by John Hawks

In my research, I find ways to bring together people and diverse methods to build a stronger understanding of the origins that we share as humans.

Over the last few years, I have spent a lot of time on projects in the Rising Star cave system of South Africa, where our team discovered the fossils of Homo naledi. With many collaborators, I am working to understand this species, its behavior, and its relationships with today's people. I have studied skeletal evidence of hominins as varied as Sahelanthropus tchadensis and Neandertals.

I also work with human and ancient DNA to test hypotheses about ancient populations and their adaptations. My work has included some of the earliest examinations of natural selection using genome-wide evidence in living humans, and analyses of introgression from Neandertals and other archaic humans.

Sharing research with the communities where I work and the global public is important to my professional life. I am committed to promoting more open and ethical practices in anthropology and genetics. You will find these areas of focus in my scientific publications and my public writing.

Research highlight: The frontal sinuses of fossil hominins

A look inside the skulls of hominins reveals the extensive variation in the form of the internal structures known as the frontal sinuses.

Research highlight: Vertebral wedging in Homo naledi

In a new paper led by Scott Williams, we look at the way that the Homo naledi lower vertebral column compares to humans and other extinct hominins.

Research highlight: The limbs of Homo naledi

In a new paper, Sarah Traynor, David Green and I show that the sizes of the arm bones of Homo naledi are more or less like today's humans, despite their many morphological adaptations to climbing.
