what are the four major categories for evidence of evolution?

The field is divided into four main areas of inquiry: modern human societies (Socio-cultural Anthropology), past human societies (Archaeology), human communication (Linguistic Anthropology), and human and primate biology (Biological Anthropology).

Evidence for evolution is provided by homologous structures. These are structures shared by related organisms that were inherited from a common ancestor. Other evidence is provided by analogous structures. These are structures that unrelated organisms share because they evolved for the same function.

Evolution over time can follow several different patterns. Factors such as environment and predation pressures can have different effects on the ways in which species exposed to them evolve. shows the three main types of evolution: divergent, convergent, and parallel evolution.

The four major branches of science are, Mathematics and logic, biological science, physical science and social science.

There are now four major fields of anthropology: biological anthropology, cultural anthropology, linguistic anthropology, and archaeology. Each focuses on a different set of research interests and generally uses different research techniques.

['Structural Adaptations. These involve the physical features of an organism that help them to survive in the environment including the different types of terrestrial habitat. ... ', 'Behavioural Adaptations. ... ', 'Physiological Adaptations.']

Fossils provide the direct evidences of organic evolution. Fossils may be entire organisms buried in sediment or snow, small part of ancient organisms or impression of extinct organisms, ancient leaf or stem.

In general, we classify diversity into 4 major Diversity Types Dimensions. The four diversity type dimensions are Internal (race, gender etc), External (education, family status, social status), Organizational (position, organization styles), and World View (political views.)

Embryology, the study of the development of the anatomy of an organism to its adult form, provides evidence for evolution as embryo formation in widely-divergent groups of organisms tends to be conserved. ... Another form of evidence of evolution is the convergence of form in organisms that share similar environments.

Trends in evolution. An evolutionary trend can be either directional change within a single lineage or parallel change across lineages, in other words, several lineages undergoing the same sort of change. However, not just any change counts as a trend.
