The most-accepted hypothesis today is that evolved from and first appeared in East Africa between 2.0 and 1.8 mya. If those are not the exact species that the human line descended through during those times, our actual ancestors were close cousins. The early adults had brains of about 850 ccs, and some later specimens reached 1,100 ccs, or triple the mass of a chimpanzee’s brain. Today’s human brain only averages about 1,200 ccs (). , as with other members of the line, had a brain that was another third larger than , and probably was responsible for its relatively sophisticated material culture. But important as its growing brain was, other anatomical changes were more telling. was fully adapted for living on the ground and walking great distances. For the first quarter-million years of existence, it lived in the Oldowan culture, which used tools and weapons that were little more than rocks with sharpened edges, and probably some shaped sticks. They evolved in a highly dangerous environment and all of their ancestors slept in trees. How could they have slept on the ground? In a word: fire.

The second is not available to the general public, but the first argues that "a significant portion of the effort of early cultivators globally was probably directed to the production of psychoactive substances, including the use of cereals, poppies, coca, sugar cane, tobacco, and cannabis," and that "a major component of the Neolithic transition was a pharmacological transition" using psychoactive substances.

Aquatic ape hypothesis - Wikipedia

A biological assessment of what has been called the puzzle of agriculture might phrase it in simple ethological terms: why was this behaviour (agriculture) reinforced (and hence selected for) if it was not offering adaptive rewards surpassing those accruing to hunter-gathering or foraging economies?

This paradox is responsible for a profusion of models of the origin of agriculture.

The Controllers: A New Hypothesis of Alien Abduction

That had thick teeth that meant that it had abandoned the arboreal ape diet and brings up perhaps the single biggest question of the early human line: “When our ancestors became bipeds?” One piece of evidence for bipedalism is where the ; if it is underneath the skull, it suggests an upright posture and, hence, bipedalism. There is had a skull hole that meant bipedalism. Skull and vertebrae evidence, changes in the shoulders, arms, and hands of apes from onward, as well as the pelvis, legs, knees, ankles, and feet, are used whenever relevant ape fossils are found to determine what kind of posture they had, all the way from swinging from branches to walking upright. The great range of motion of the human arm has that arboreal heritage to thank.

Orangutans are the most arboreal great ape, and in Africa the great apes had definitely left the trees as their daytime residence, although they slept in trees to avoid predators. Gorillas can primarily subsist on leafy vegetation, although the staple of the , which is the most prevalent gorilla species, . . Gorillas usually have a smaller daily range than chimpanzees have and live in the heart of rainforests; what became chimpanzees were probably pushed to the margins by their larger cousins and live more along a rainforest’s woodland fringes. They have to range relatively far to find their staple: . Since their diet is more diverse and they can survive in more varied environments, the chimpanzees’ range is than that of . Like the largest quadrupedal herbivores, gorillas ingest a great deal of low-calorie vegetation each day and are that extract energy from cellulose, which humans cannot do. Chimpanzees are also hindgut fermenters. As with all organisms, the ecological situation of great apes influenced their evolution, including social organization and behaviors. This has been increasingly studied since the 19th century and has provided valuable insights into humanity, some of which follow.

The study of intelligence is a young science, and the relationship of brain size (both absolute and relative) and structure to what is called intelligence is currently subject to a great deal of research and controversy, and even the is hotly debated. The appeared with mammals, and is the key structural aspect of brain evolution that led to human intelligence. The attempts to determine which , and those suspected of being the most intelligent have passed the test, including all great apes, cetaceans, elephants, and even a bird. Humans do not pass the mirror test until about 18 months of age. There is great debate between those embracing "rich" versus "lean" interpretations of behavior and intelligence observations among animals, in which seemingly complex thinking can be an illusion.
