[47] [48] Brain expansion (enlargement) between 0.8 and 0.2 Ma may have occurred due to the extinction of most African megafauna (which made humans feed from smaller prey and plants, which required greater intelligence due to greater speed of the former and uncertainty about whether the latter were poisonous or not), extreme climate variability ...
Human intelligence is the intellectual capability of humans, which is marked by complex cognitive feats and high levels of motivation and self-awareness.Using their intelligence, humans are able to learn, form concepts, understand, and apply logic and reason.
Human intelligence is the intellectual power of humans, which is marked by complex cognitive feats and high levels of motivation and self-awareness. [ 23 ] [ 24 ] Intelligence enables humans to remember descriptions of things and use those descriptions in future behaviors.
Genes involved in the neuro-development and in neuron physiology are extremely conserved between mammalian species (94% of genes expressed in common between humans and chimpanzees, 75% between humans and mice), compared to other organs. Therefore, few genes account for species differences in the human brain development and function. [15]
Moreover, the cerebral cortex of the human brain – which plays a key role in memory, attention, awareness and thought – contains twice as many cells in humans as the same region in chimpanzees. [4] Secondly, the recent evolution of chimpanzees and humans has been in completely different environments, with different survival needs.
The human consciousness is structured in hierarchical order and organized in "holon" chains or "great chain of being", which are based on the level of spiritual and psychological development. [ 117 ] Oliver Kress published a model that connected Piaget's theory of development and Abraham Maslow 's concept of self-actualization . [ 118 ]
Real-world experience is necessary to and for the development of a person's intellect, because, in resolving the problems of life, a person can intellectually comprehend a social circumstance (a time and a place) and so adjust their social behavior in order to act appropriately in the society of other people.
