Caption: Composite reconstruction of the earliest known Homo sapiens fossils from Jebel Irhoud (Morocco) based on micro computed tomographic scans of multiple original fossils. Dated to 300 thousand years ago these early Homo sapiens already have a modern-looking face that falls within the variation of humans living today. However, the archaic-looking virtual imprint of the braincase (blue) indicates that brain shape, and possibly brain function, evolved within the Homo sapiens lineage.

Moroccan fossils show human ancestors’ diet of game
June 7, 2017
Summary: New fossil finds from Morocco do more than push back the origins of our species by 100,000 years. They also reveal what was on the menu for our oldest-known Homo sapiens ancestors 300,000 years ago: Plenty of gazelle.
New fossil finds from the Jebel Irhoud archaeological site in Morocco do more than push back the origins of our species by 100,000 years. They also reveal what was on the menu for our oldest-known Homo sapiens ancestors 300,000 years ago:
Plenty of gazelle meat, with the occasional wildebeest, zebra and other game and perhaps the seasonal ostrich egg, says Teresa Steele, a paleoanthropologist at the University of California, Davis, who analyzed animal fossils at Jebel Irhoud.
Steele, who studies how food sources and environmental change influenced human evolution and migration, was part of the international research team that began excavating at the site in 2004. She is the co-author of one of two papers featured on the cover of the June 8 issue of Nature: “Human origins: Moroccan remains push back date for the emergence of Homo sapiens.”
Jebel Irhoud has been well known since the 1960s for its human fossils and for its Middle Stone Age artifacts, but the geological age of those fossils was uncertain.
The new excavation project — led by Jean-Jacques Hublin of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, and Abdelouahed Ben-Ncer of the National Institute for Archaeology and Heritage (INSAP) in Rabat, Morocco — uncovered 16 new Homo sapiens fossils along with stone tools and animal bones. The remains comprise skulls, teeth, and long bones of at least 5 individuals.
Thermoluminescence dating of heated flints yielded an age of approximately 300,000 years ago — 100,000 years earlier than the previously oldest Homo sapiens fossils.
Analysis of the animal fossils provided additional evidence to support the date. Dating of rodent remains suggested they were 337,000 to 374,000 years old.
Gazelle Bones Common
Steele sifted through hundreds of fossil bones and shells, identifying 472 of them to species as well as recording cut marks and breaks indicating which ones had been food for humans.
Most of the animal bones came from gazelles. Among the other remains, Steele also identified hartebeests, wildebeests, zebras, buffalos, porcupines, hares, tortoises, freshwater molluscs, snakes and ostrich egg shells.
Small game was a small percentage of the remains. “It really seemed like people were fond of hunting,” she said.
Cuts and breaks on long bones indicate that humans broke them open, likely to eat the marrow, she said. Leopard, hyena and other predators’ fossils were among the finds, but Steele found little evidence that the nonhuman predators had gnawed on the gazelle and other prey.
Steele said the findings support the idea that Middle Stone Age began just over 300,000 years ago, and that important changes in modern human biology and behaviour were taking place across most of Africa then.
“In my view, what it does is to continue to make it more feasible that North Africa had a role to play in the evolution of modern humans.”

A scientific consortium has found that human ancestors were scattered across Africa, and largely kept apart by a combination of diverse habitats and shifting environmental boundaries, such as forests and deserts. Millennia of separation gave rise to a staggering diversity of human forms, whose mixing ultimately shaped our species: here.
