According to Israeli-led researchers, humans began to cook food hundreds of thousands of years earlier than we thought. Evidence to support this was found in the 780,000-year-old remains of a huge carp-like fish that was discovered in northern Israel. Before this, the earliest evidence of cooking dated back to 170,000 B.C. Many crystals were found in the enamel of the fish’s teeth. When studied, researchers found that they hadn’t been exposed to direct fire but rather cooked at a low temperature.
