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.
Quantitative genetics – study of phenotypes that vary continuously (in characters such as height or mass)—as opposed to discretely identifiable phenotypes and gene-products (such as eye-colour, or the presence of a particular biochemical). Marine biology – study of ocean ecosystems, plants, animals, and other living beings.
In biology, phylogenetics (/ ˌ f aɪ l oʊ dʒ ə ˈ n ɛ t ɪ k s,-l ə-/) [1] [2] [3] is the study of the evolutionary history of life using genetics, which is known as phylogenetic inference. It establishes the relationship between organisms with the empirical data and observed heritable traits of DNA sequences, protein amino acid sequences ...
Biology is the scientific study of life. [ 1 ] [ 2 ] [ 3 ] It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field. [ 1 ] [ 2 ] [ 3 ] For instance, all organisms are made up of at least one cell that processes hereditary information encoded in genes , which can be transmitted ...
The following outline is provided as an overview of and topical guide to neuroscience: Neuroscience is the scientific study of the structure and function of the nervous system. [1] [2] It encompasses the branch of biology [3] that deals with the anatomy, biochemistry, molecular biology, and physiology of neurons and neural circuits.
The Society for Molecular Biology and Evolution was founded in 1982. Molecular phylogenetics Multiple sequence ... In a proof-of-concept study, ...
Ecological evolutionary developmental biology [c] integrates research from developmental biology and ecology to examine their relationship with evolutionary theory. [78] Researchers study concepts and mechanisms such as developmental plasticity , epigenetic inheritance , genetic assimilation , niche construction and symbiosis .
Within the study of human societies, sociobiology is closely allied to evolutionary anthropology, human behavioral ecology, evolutionary psychology, [1] and sociology. [2] [3] Sociobiology investigates social behaviors such as mating patterns, territorial fights, pack hunting, and the hive society of social insects.
