New fossil finds from the Jebel Irhoud archaeological site in Morocco do more than push back the origins of our species by , years. They also reveal what was on the menu for our oldest-known Homo sapiens ancestors , 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 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 s for its human fossils and for its Middle Stone Age artifacts, but the geological age of those fossils was uncertain. The remains comprise skulls, teeth, and long bones of at least 5 individuals. Thermoluminescence dating of heated flints yielded an age of approximately , years ago — , 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 , to , years old.

In contrast, separated fats are staples for contemporary humans. Sure enough, most prosimians are and likely were carnivores. Studies suggest that indigenous groups get into trouble when they abandon their traditional diets and active lifestyles for Western living. Written by an academic. Stringer, Christopher B.

Survival depends on the animals that they milk, butcher, and barter. Dietary fiber was first thought to reduce colon cancer susceptibility, and then it was found to have no such effect. Aside from casual interest, there is a reason to appreciate the nutrition that fueled nearly all of human evolution. Although cupcakes and crumpets were still a long way off during the Middle Stone Age, new evidence suggests that at least some humans of that time period were eating starchy, cereal-based snacks as early as , years ago. Our teeth, jaws, and faces have gotten smaller, and our DNA has changed since the invention of agriculture. In the United States, alcohol provides from 3 to 5 percent of the average adult’s daily caloric intake. There are many ways to think about food. Nutritionists follow Stone Age practice when they argue that it is better to obtain micronutrients from real foods rather than from capsules. When people were required to settle more or less permanently in a given area, grain consumption became a viable option because other types of plant and animal food became increasingly difficult to obtain. If you have just eaten a twinkie, the process essentially ends there. Well worth reading.
