Document Summary
Lesula newest primate species, striking human resembles. Evolution: the change in the inherited characteristics of biological populations over successive generations meaning that changes occur gradually, over times. Genetic mutation and shift- this happens quickly and seen within one generation. Darwin dreampond here we can see that changing certain traits can insure the survival of a species, and this usually occur within a generation. Traits can be explained by the type of food that they consume, and thus diet produce gradual changes in a specie. Thomas henry huxley: evidence as to man"s place in nature (1863) - this was controversial as seen as heresy, was before darwin. Brain development: temporal lobes (language) prefrontal cortex (decision making and planning) account for most of the brain. Large prefrontal cortex have originated from animals and makes language and decision making possible. Language is necessary because we are social creatures.
