Sociobiology is a field of biology that aims to explain social behavior in terms of evolution.It draws from disciplines including psychology, ethology, anthropology, evolution, zoology, archaeology, and population genetics.
Neo-evolutionism discards many ideas of classical social evolutionism, namely that of social progress, so dominant in previous sociology evolution-related theories. [68] Then neo-evolutionism discards the determinism argument and introduces probability, arguing that accidents and free will greatly affect the process of social evolution. [68]
The biological basis of personality is a collection of brain systems and mechanisms that underlie human personality. Human neurobiology, especially as it relates to complex traits and behaviors, is not well understood, but research into the neuroanatomical and functional underpinnings of personality are an active field of research.
The lifespan perspectives of personality are based on the plasticity principle, the principle that personality traits are open systems that can be influenced by the environment at any age. [5] Large-scale longitudinal studies have demonstrated that the most active period of personality development appears to be between the ages of 20–40. [ 5 ]

The march of progress is the canonical representation of evolution – the one picture immediately grasped and viscerally understood by all. ... The straitjacket of linear advance goes beyond iconography to the definition of evolution: the word itself becomes a synonym for progress. ...
In biology, evolution is the process of change in all forms of life over generations, and evolutionary biology is the study of how evolution occurs. Biological populations evolve through genetic changes that correspond to changes in the organisms ' observable traits .
The theory of evolution by natural selection has also been adopted as a foundation for various ethical and social systems, such as social Darwinism, an idea that preceded the publication of The Origin of Species, popular in the 19th century, which holds that "the survival of the fittest" (a phrase coined in 1851 by Herbert Spencer, [1] 8 years before Darwin published his theory of evolution ...
