In biology, the question of the individual is related to the definition of an organism, which is an important question in biology and the philosophy of biology, despite there having been little work devoted explicitly to this question. [3] An individual organism is not the only kind of individual that is considered as a "unit of selection". [3]
A colonial organism such as a siphonophore is a being which functions as an individual but is composed of communicating individuals. [8] A superorganism is a colony, such as of ants , consisting of many individuals working together as a single functional or social unit .
This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
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 composed of at least one cell that processes hereditary information encoded in genes , which can be transmitted ...
The idea of biology-based personality research is relatively new, but growing in interest and number of publications. [7] In August 2004, there was a conference specifically on the topic, called The Biological Basis of Personality and Individual Differences. [8]
The hierarchy of biological classification's eight major taxonomic ranks. A genus contains one or more species. Minor intermediate ranks are not shown. A species (pl.: species) is a population of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. [1]
An example of random variation in Drosophila flies is the number of ommatidia, which may vary (randomly) between left and right eyes in a single individual as much as they do between different genotypes overall, or between clones raised in different environments. [citation needed]
An example of direct competition. Intraspecific competition is an interaction in population ecology , whereby members of the same species compete for limited resources. This leads to a reduction in fitness for both individuals, but the more fit individual survives and is able to reproduce. [ 1 ]
