New research suggests that [usage / using] fire to cook food started 600,000 years before previously [thinking / thought] . Archeologists from the Tel Aviv University's Steinhardt Museum of Natural History in Israel [assert / covert] that our early [ancestors / ancestry] cooked fish with fire 770,000 years ago. The archaeologists [claim / clam] that these prehistoric humans, who lived [longingly / alongside] the banks of the Jordan River in what is present-day northern Israel, used fire to cook the "huge fish" they [net / caught] in a nearby lake. They say their [finding / founding] is the earliest recorded evidence of food being cooked. Until this new discovery, scientists believed the first "[definitive / definitely] evidence" of cooking was by Neanderthals and early [Homo / Human] sapiens, around 170,000 years ago.
Lead researcher Irit Zohar spent 16 years analyzing ancient fish bones and the [enamel / fluoride] found on fish teeth. Her analysis showed that the grilled or [braked / baked] fish had been eaten 770 millennia ago. She told the AFP news agency that: "It was like facing a [puzzlement / puzzle] , with more and more information until we could make a story about human [evolution / elocution] ." She added that her biggest conundrum was to [concertina / ascertain] whether or not the fish had been eaten [gnaw / raw] and then their bones thrown into the fire, or [wherewithal / whether] it had been cooked first. She said: "The whole question about [exposition / exposure] to fire is whether it is about getting [riddance / rid] of remains or a desire to cook." She said the fish were two-metre-long carp, that would have been particularly [succinct / succulent] when cooked.
