"Sociobiology is now part of the core research and curriculum of virtually all biology departments, and it is a foundation of the work of almost all field biologists. " Sociobiological research on nonhuman organisms has increased dramatically and continuously in the world's top scientific journals such as Nature and Science.
The proposal implied (if it were correct) a shared phylogeny of tunicates and vertebrates, and that heterochrony was a principal mechanism of evolutionary change. [6] Modern evolutionary developmental biology (evo-devo) studies the molecular genetics of development.
Each behavioural change theory or model focuses on different factors in attempting to explain behaviour change. Of the many that exist, the most prevalent are learning theories, social cognitive theory, theories of reasoned action and planned behaviour, transtheoretical model of behavior change, the health action process approach, and the BJ Fogg model of behavior change.
Biological Theory is a peer-reviewed scientific journal covering the fields of evolution and cognition, including cognitive psychology, epistemology, philosophy of science, philosophy of biology, evolutionary biology, and developmental biology.
Genetic heterogeneity occurs through the production of single or similar phenotypes through different genetic mechanisms. There are two types of genetic heterogeneity: allelic heterogeneity, which occurs when a similar phenotype is produced by different alleles within the same gene; and locus heterogeneity, which occurs when a similar phenotype is produced by mutations at different loci.
A heterogeneous taxon, a taxon that contains a great variety of individuals or sub-taxa; usually this implies that the taxon is an artificial grouping; Genetic heterogeneity, multiple origins causing the same disorder in different individuals. Allelic heterogeneity, different mutations at the same locus causing the same disorder.
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.
However, for those who are not familiar with the theoretical psychology surrounding a theory, the abundant amount of information contributing to a theory can be overwhelming. [17] In addition, theories can be extremely resistant to change. As theories compete, and different evidence emerges, prior theories can be extremely difficult to change.
