New research provides the first direct evidence that Australopithecus, an important early human ancestor that displayed a mix of ape-like and human-like traits, consumed very little or no meat ...
This finding provides both the clearest evidence of meat eating by early human ancestors and the association of earliest stone tools with the butchering of animals for meat and marrow. [8] This co-occurrence of stone tools is clearly linked with the butchering of animals and earliest identifiable appearances of Homo habilis. [9]
In the 21st century, the sequencing of the human genome and DNA analysis of the remains of early humans have found evidence that humans evolved rapidly in response to changing diet. This evidence undermines a core premise of the paleolithic diet – that human digestion has remained essentially unchanged over time. [5]
The thickening of enamel in australopiths may have been a response to eating more ground-bound foods such as tubers, nuts, and cereal grains with gritty dirt and other small particulates which would wear away enamel. Gracile australopiths had larger incisors, which indicates tearing food was important, perhaps eating scavenged meat.
The advent of agriculture roughly 11,500 years ago in the Middle East was a milestone for humankind - a revolution in diet and lifestyle that moved beyond the way hunter-gatherers had existed ...
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.
Wrangham also argues that cooking and control of fire generally affected species development by providing warmth and helping to fend off predators, which helped human ancestors adapt to a ground-based lifestyle. Wrangham points out that humans are highly evolved for eating cooked food and cannot maintain reproductive fitness with raw food. [3]
The debate over whether or not eating meat really did “make us human” just became more complicated.
