The evidence of early Homo sapiens diet stems from multiple lines of evidence, and there is a relative abundance of information due to both a larger relative population footprint and more recent evidence. A key contribution to early human diet likely was the introduction of fire to hominins toolkit.
Early human nutrition was largely determined by the availability and palatability (tastiness) of foods. [2] Humans evolved as omnivorous hunter-gatherers, though our diet has varied significantly depending on location and climate. Historically, the diet in the tropics tended to depend more heavily on plant foods, while diet at higher latitudes ...
The incorporation of meat into the diet was a milestone for the human evolutionary lineage, a potential catalyst for advances such as increased brain size. New research provides the first direct ...
With its high caloric density and content of important nutrients, meat thus became a staple in the diet of early humans. [54] By increasing digestibility, cooking allowed hominids to maximize the energy gained from consuming foods. Studies show that caloric intake from cooking starches improves 12-35% and 45-78% for protein.
Catching Fire: How Cooking Made Us Human is a 2009 book by British primatologist Richard Wrangham, published by Profile Books in England, and Basic Books in the US. It argues the hypothesis that cooking food was an essential element in the physiological evolution of human beings. It was shortlisted for the 2010 Samuel Johnson Prize.
Possible early ancestors of catarrhines include Aegyptopithecus and Saadanius. 35-20 Ma Proconsul. Catarrhini splits into 2 superfamilies, Old World monkeys (Cercopithecoidea) and apes . Human trichromatic color vision had its genetic origins in this period. Catarrhines lost the vomeronasal organ (or possibly reduced it to vestigial status).
A trove of snake fossils dating to about 6,000 years ago were found in the Zuojiang River Basin.
Human nutrition deals with the provision of essential nutrients in food that are necessary to support human life and good health. [1] Poor nutrition is a chronic problem often linked to poverty, food security , or a poor understanding of nutritional requirements. [ 2 ]
