Egyptian fossil ape challenges east Africa origins theory

A newly discovered fossil ape from northern Egypt, named Masripithecus moghraensis, dates to 17-18 million years ago and may be closely related to the ancestors of modern apes. Researchers argue this finding shifts the focus from East Africa to northern Africa for early ape evolution. The species provides key insights into hominoid diversity during a period of continental connections.

Researchers have identified a new fossil ape species, Masripithecus moghraensis, unearthed in the Wadi Moghra region of northern Egypt. Dated to around 17-18 million years ago, the specimen offers fresh evidence on the origins of modern apes, including humans. Shorouq Al-Ashqar and colleagues describe it as a stem hominoid closely linked to the lineage leading to all living apes, according to their analysis published in Science this year (DOI: 10.1126/science.adz4102). Using a Bayesian tip-dating method, which integrates anatomical traits with fossil ages, the team positioned Masripithecus near the base of crown-hominoid evolution. Early apes, or stem hominoids, emerged in Afro-Arabia over 25 million years ago during the Oligocene. By the Miocene, around 14-16 million years ago, some spread into Eurasia as land connections formed. However, fossil gaps, especially in Africa's vast unexplored areas, have left the precise origins of modern apes unclear. This discovery highlights ape diversity when Afro-Arabia linked to Eurasia, suggesting modern apes may have arisen in northern Afro-Arabia, the Levant, or the eastern Mediterranean. David Alba and Júlia Arias-Martorell noted in a related perspective: “[The] findings […] confirm that paleontologists might have been looking for crown-hominoid ancestors in the wrong place.” The find challenges the traditional emphasis on East African sites, urging broader searches across northern Africa and adjacent regions.

Researchers have found fossil teeth in Ethiopia indicating that early Homo and an unknown Australopithecus species shared the landscape between 2.6 and 2.8 million years ago. The discovery adds to evidence that human evolution involved multiple overlapping lineages rather than a single straight path.

Ethiopia's Authority for Research and Conservation of Cultural Heritage announced discovery of Homo sapiens fossils from 100,000 years ago in the Middle Awash area of the Afar region. The study, led by Dr. Yonas Beyene with scientists from 24 countries, fills key gaps in Africa's human origins timeline.

Scientists have identified a new species of land-dwelling crocodylomorph from 215 million years ago in Gloucester, UK. Named Galahadosuchus jonesi, the reptile had a slender, greyhound-like build for fast movement on land. The discovery honors a schoolteacher who inspired the lead researcher.

A crushed dinosaur fossil, long forgotten in a drawer, has been reconstructed by a Virginia Tech undergraduate, unveiling a new species of early carnivorous dinosaur. The specimen, named Ptychotherates bucculentus, belonged to the Herrerasauria group and lived near the end of the Triassic period. Its discovery suggests this ancient dinosaur lineage persisted until the end-Triassic extinction.
