A recent study shows that insects may be forming nearly half of the daily diet of millions of years early people. Previously, it was thought that early humans were feeding on large mammals with flesh or with nuts and leaves.
However, academics from Herio-Watt University and Wayne State University have shown that insects may be a basic food source for humans, making nearly 50% of their predecessor's diet approximately 1.8 million years ago.
The discovery was made incidentally as a result of tests on strange-looking mud taken during excavations in Olduvai Gorge, Tanzania.
While the mud was being tested in Heriot-Watt laboratories, it was confirmed that the sediments actually belonged to an ancient termite deposit
After the carbon footprints in the fossil dunes on the excavation site were compared to the carbon footprints in the possible food source, the academics made this groundbreaking discovery.
