/news/wp-json/wp/v2/posts/150683/u201cEven though both fossils are separated by hundreds of thousands of years, they reveal unexpected combinations of traits that suggest early human evolution was shaped by regional evolution, migrations and interactions,/news/wp-json/wp/v2/posts/150683/u201d Freidline says. /news/wp-json/wp/v2/posts/150683/u201cAfrica wasn/news/wp-json/wp/v2/posts/150683/u2019t just the birthplace of early humans, but a place where multiple populations coexisted and evolved in different ways./news/wp-json/wp/v2/posts/150683/u201d/news/wp-json/wp/v2/posts/150683/n
Advanced Imaging Reveals Hidden Details/news/wp-json/wp/v2/posts/150683/n Unlocking the new findings required more than fossils alone. Both studies relied on advanced technologies such as micro-CT scanning, digital reconstruction and comparative anatomical analysis, including geometric morphometrics, to extract new information from fossil fragments./news/wp-json/wp/v2/posts/150683/n
/news/wp-json/wp/v2/posts/150683/u201cFor the DAN5 fossil, the facial bones were fragmented, so we used CT data to virtually reconstruct the face, fitting the pieces together like a 3D puzzle,/news/wp-json/wp/v2/posts/150683/u201d Freidline says. /news/wp-json/wp/v2/posts/150683/u201cOnce reconstructed, I applied geometric morphometrics to capture subtle shape differences to compare fossils across time and geography without size bias./news/wp-json/wp/v2/posts/150683/u201d/news/wp-json/wp/v2/posts/150683/n
In Morocco, magnetostratigraphic dating provided one of the most secure timelines for any African Pleistocene hominin assemblage, while virtual reconstruction techniques allowed scientists to visualize fossils that couldn/news/wp-json/wp/v2/posts/150683/u2019t be physically reassembled./news/wp-json/wp/v2/posts/150683/n

/news/wp-json/wp/v2/posts/150683/u201cTraditional methods to analyze fossils rely heavily on linear measurements, like length and width, which are useful but limited,/news/wp-json/wp/v2/posts/150683/u201d she says. /news/wp-json/wp/v2/posts/150683/u201cGeometric morphometrics allow us to isolate shape independently of size, which is crucial when comparing fossils of different sizes./news/wp-json/wp/v2/posts/150683/u201d/news/wp-json/wp/v2/posts/150683/n
Freidline says this method has become the standard in paleoanthropology over the years, but it remains a specialized skill set requiring advanced software and programming. She brings this expertise to both her research and teaching at UCF./news/wp-json/wp/v2/posts/150683/n
Where Discovery Leads Next/news/wp-json/wp/v2/posts/150683/n Looking ahead, researchers hope to compare the Ethiopian and Moroccan fossils with other early human remains from Africa and Europe to better understand how ancient populations were related and how traits were passed on over time./news/wp-json/wp/v2/posts/150683/n
