London, Dec 18 (ANI): The practice of eating cereal in the morning dates back more than 100,000 years, say scientists.

Tools and plant remains from a cave in Mozambique represent the earliest evidence of human reliance on grains for sustenance, according to Julio Mercader, the University of Calgary researcher who uncovered the artifacts, reports The Daily Express.

According to the expert, our ancestors were grinding wild grass grains at the start of the last ice age - 90,000 years earlier than had been thought, when early hunter-gatherers were believed to have relied on fruits, roots and nuts.

The limestone cave at Ngalue in north-west Mozambique, was used by Stone Age foragers for 60,000 years.

Dr Mercader said: “This is proof of an expanded and sophisticated diet much earlier than we believed.” (ANI)
