Evidence for animal culture is often based on studies of feeding behaviors, [8] vocalizations, [4] predator avoidance, [9] mate selection, [10] and migratory routes. [11] An important area of study for animal culture is vocal learning, the ability to make new sounds through imitation. [4] Most species cannot learn to imitate sounds.
Cultural evolution is an evolutionary theory of social change. It follows from the definition of culture as "information capable of affecting individuals' behavior that they acquire from other members of their species through teaching, imitation and other forms of social transmission". [1] Cultural evolution is the change of this information ...
Many aspects of an animal or plant can be correctly called adaptations, though there are always some features whose function remains in doubt. By using the term adaptation for the evolutionary process , and adaptive trait for the bodily part or function (the product), one may distinguish the two different senses of the word.
It became clear that the diversity of animal morphology was not the result of different sets of proteins regulating the development of different animals, but from changes in the deployment of a small set of proteins common to all animals. [168] These proteins became known as the "developmental-genetic toolkit."
Dual inheritance theory (DIT), also known as gene–culture coevolution or biocultural evolution, [1] was developed in the 1960s through early 1980s to explain how human behavior is a product of two different and interacting evolutionary processes: genetic evolution and cultural evolution.
He postulated that different cultures form separate methods that meet different needs, but when two cultures were in contact they developed similar adaptations, solving similar problems. Rejecting Spencer's theory of parallel cultural evolution, Childe found that interactions between cultures contributed to the convergence of similar aspects ...
Adaptationism is an approach to studying the evolution of form and function. It attempts to frame the existence and persistence of traits, assuming that each of them arose independently and improved the reproductive success of the organism's ancestors.
Humans determine which animal or plant will reproduce and which of the offspring will survive; thus, they determine which genes will be passed on to future generations. The process of artificial selection has had a significant impact on the evolution of domestic animals. For example, people have produced different types of dogs by controlled ...
