1A recent study found what could be the earliest known evidence of ancient cooking: the leftovers of a fish dinner from 780,000 years ago.
2Cooking helped change our ancestors.
3It helped fuel our evolution and gave us bigger brains.
4Later, cooking would become central to the eating celebrations that brought communities together.
5The new study, published in Nature Ecology and Evolution, is based on material from Gesher Benot Ya'aqov in Israel - a watery place near an ancient lake.
6Ancient objects from the area suggest it was home to a community of Homo erectus, a kind of early human that walked upright, explained study lead writer Irit Zohar of Tel Aviv University.
7Naama Goren-Inbar of the Hebrew University of Jerusalem led the research digs.
8She said researchers found fish remains, especially teeth.
9Many of the teeth were from two different kinds of fish known as carp.
10The remains were found near places where researchers also found signs of fire.
11Testing showed the teeth had been exposed to temperatures that were hot, but not super-hot.
12This suggests the fish were cooked low and slow, rather than being put right onto a fire, Zohar explained.
13With all the evidence together, researchers concluded that these ancient human relatives had used fire for cooking some 780,000 years ago.
14That is much earlier than the next oldest evidence for cooking, about 170,000 years ago, which showed Stone Age humans ate cooked roots in South Africa.
15The researchers - like many other experts - believe cooking started long before this, though physical evidence has been hard to find.
16"I am sure that in the near future an earlier case will be reported," study writer Israel Hershkovitz of Tel Aviv University said in an email.
17That is in part because using fire for cooking was an important step in human evolution.
18Cooking food makes it easier for the body to digest and get nutrients, explained David Braun of George Washington University.
19Braun was not involved with the study.
20When early humans figured out how to cook, they were able to get more energy, which they could use to fuel bigger brains.
21Based on how human ancestors' brains and bodies developed, scientists estimate that cooking skills appeared nearly 2 million years ago.
22"If we're out there eating raw items, it is very difficult to make it as a large-bodied primate," Braun said.
23Those first cooked meals were far different from today's food.
24And in the many, many years in between, humans started not just eating for fuel, but for community.
25In a 2010 study, led by Natalie Munro of the University of Connecticut, researchers described the earliest evidence of a feast.
26The feast was a specially prepared meal that brought people together for an event 12,000 years ago in a cave in Israel.
27The cave, which served as a burial place, included the remains of one special woman who seemed to be a religious leader for her community, Munro said.
28This "first feast" came at an important turning point in human history, right as hunter-gatherers were starting to settle into more permanent living situations, Munro said.
29Gathering for special meals may have been a way to build community and reduce tensions now that people lived closer to each other, she said.
30Munro said she believes ancient feasts served a lot of the same social uses that modern gatherings serve:
31People exchange information, make connections, or try to improve their position.
32"This is something that's just quintessentially human," Munro said.
33"And to see the first evidence of it is exciting."
