Diet of early man varied in harmony with the seasons: NewsTarget.com

Tucson, Ariz. – According to new research published in the journal Science, early humans changed their eating habits from month to month, depending on the season, which refutes a previously held belief that early Man died out because it could not adapt its diet to changing climates.

A chemical analysis of the teeth of an early human believed to be 1.8 million years old revealed that the ancient hominid adapted its feeding habits on a monthly basis, which indicates it lived a nomadic lifestyle.

The teeth were found in a skull that was discovered at Swartkrans in South Africa. The shape and buildup of the teeth initially led researchers to believe that the hominid became extinct because its diet was too specialized to adapt to climate change. However, a chemical analysis of the teeth revealed that the species lived on fruit, nuts, grasses, sedges (grasses with solid stems), seeds, herbs, tubers, tree leaves and roots. The researchers believe the hominid may have consumed animal meat, but could not determine if it hunted or scavenged meat.

The team of scientists from the University of Utah also said in its report that the teeth reflected dietary changes based on annual rainfall.
