The control of fire by early humans was a critical technology enabling the evolution of humans. Fire provided a source of warmth and lighting, protection from predators (especially at night), a way to create more advanced hunting tools, and a method for cooking food. These cultural advances allowed human geographic dispersal, cultural ...
Human cannibalism is the act or practice of humans eating the flesh or internal organs of other human beings. A person who practices cannibalism is called a cannibal. The meaning of "cannibalism" has been extended into zoology to describe animals consuming parts of individuals of the same species as food.
Drawing on hundreds of studies in relation to the kuru disease which is only known to spread through cannibalism, researchers concluded that the 127V gene, which is known for resisting kuru-like diseases, indicates widespread cannibalism among early humans. If modern humans and Neanderthals, who co-existed at that time, both practised ...
An index that can be used as a measure is the Efficiency of conversion of ingested food to body substance: for example, only 10% of ingested food is converted to body substance by beef cattle, versus 19–31% by silkworms and 44% by German cockroaches.

There's a reason U.S. health officials recommend eating chicken when it's fully cooked. Unlike red meats like meat or lamb, poultry often harbors harmful bacteria like salmonella.
H. erectus is the first known species to develop control of fire, by about 1.5 Ma. H. erectus later migrates throughout Eurasia, reaching Southeast Asia by 0.7 Ma. It is described in a number of subspecies. [38] Early humans were social and initially scavenged, before becoming active hunters.
To put that 60% in perspective, chimpanzees, our closest living evolutionary relative, share 96% of the same genes with humans. Related: Look at these human-like chickens wearing sweaters:
