Darwin's General Summary and Conclusions of the Descent of Man and Selection in Relation to Sex

Darwin's summary and conclusions on human declines and sex-related choices Among the "summaries and conclusions" on human decline and gender selection, Charles Darwin says that people are not creative work for individual behavior I insist. Instead, he believes that humans have evolved from lower existence to today's existence. When Darwin asked for evidence to support his claim, he focused on the "whole organic world" [i] using the evolution of flora and fauna to explain his view.

Darwin did not want to comment on the nature of man in the origin of the species, but later announced human-related works such as "Decline of Man" and "Selection Regarding Sex" (1871). In the first place, "Expressions of human and animal emotions" (1872). In these works, Darwin generally focuses on the anatomical features and the evidence they provide in supporting the theory of continuity evolution of species; despite that, he is the basis of repetition I called "mentality" as a feature and explanation.

Charles Darwin is often regarded as the first scientist to pay serious attention to the study of the emotions of animals. In his study of species origin (1859), his decline and sex-related choices (1871), and human and animal emotional expression (1872), Darwin has continuity between people I believed it. The emotional (and cognitive) life of sex animals; not a big gap, there is a transitional phase between species, and the difference between many animals is rather rather than the difference in species

Animal's emotions: Exploring passionate nature: Current interdisciplinary research provides compelling evidence that many animals are experiencing emotions such as happiness, fear, love, despair, sorrow I will.

The two books after him were written about the emotion and psychology of animals, the decline of mankind in 1871, the choice of gender in 1872 and the emotional expression of humans and animals. Darwin's research stimulated William James's approach to psycho-functionalism. Darwin's theory of evolution, adaptation theory, and natural selection theory provide insight as to how the brain works. The paper by WD Hamilton (1964) on comprehensive adaptation and reciprocity and Robert Trivers (1972) on parents' investment contribute to the evolutionary thinking development in psychology and other social sciences. In 1975, Edward O. Wilson collaborated with Lorenz and Timbergen in his book "Social Biology: New Synthesis" to combine evolution theory with animal and social behavior studies.
