For over a century, scientists have searched fossil records for clues to how early human ancestors evolved, migrated and separated across Africa and beyond. Today, researchers such as Sarah Freidline, an assistant professor in the UCF Department of Anthropology, are revisiting those clues with new insights and advanced imaging techniques./news/wp-json/wp/v2/posts/150683/n

In two recent studies, Freidline and her collaborators analyzed evidence from fossil sites in eastern and northwestern Africa, revealing surprising findings of early human evolution dating back nearly 1.5 million years. While both studies focus on describing fossil remains and understanding their place in human evolutionary history, Freidline, a co-author of the studies, says each addresses different questions and regions./news/wp-json/wp/v2/posts/150683/n

Originally described in 2020, the new study expands earlier work on the braincase by examining the fossil/news/wp-json/wp/v2/posts/150683/u2019sfacial bones and teeth, which had not previously been fully analyzed. Using advanced imaging techniques, the research team digitally reassembled fragments of the face and teeth to reconstruct the most complete Early Pleistocene human cranium from the Horn of Africa./news/wp-json/wp/v2/posts/150683/n
