Agriculture likely began during the Neolithic Era before roughly 9000 BCE when polished stone tools were developed and the last ice age ended.
The first agriculture appears to have developed at the closing of the last Pleistocene glacial period, or Ice Age (about 11,700 years ago).
Since its first tentative steps during the Neolithic era, agriculture has been a major driving force behind human culture for about 10,000 years.How long have humans been on earth?
But fragments of 300,000-year-old skulls, jaws, teeth and other fossils found at Jebel Irhoud, a rich site also home to advanced stone tools, are the oldest Homo sapiens remains yet found.
Homo sapiens, who are the modern form of humans evolved 300,000 years ago from Homo erectus. Human civilizations started forming around 6,000 years ago.What did humans eat before agriculture was invented?
By about two and a half million years ago, early humans started to occasionally eat meat. By about 2 million years ago, this happened more regularly. By probably about a million and a half years ago, humans started to get the better parts of animals. They shifted from just scavenging the leftovers to maybe getting earlier access to carcasses.
A Stone Age diet “is the one and only diet that ideally fits our genetic makeup,” writes Loren Cordain, an evolutionary nutritionist at Colorado State University [...] After studying the diets of living hunter-gatherers and concluding that 73 percent of these societies derived more than half their calories from meat, Cordain came up with his own Paleo prescription: Eat plenty of lean meat and fish but not dairy products, beans, or cereal grainsWhat fueled the brain before agriculture?
The growth of the human brain is evolutionarily outstanding, because the brain is a costly organ. The Homo sapiens brain uses 20% of the body's oxygen at rest despite making up only 2% of the body's weight.
