Adaptation in Biological Definition

Experimental evolution

... of the large number of generation required for adaptation to occur, evolution experiments are typically ... that he had clearly found evidence for Darwinian adaptation in his incubator, and that the organisms had ... experimental evolution in Escherichia coli . I. adaptation and divergence during 2,000 generations. ...

Culture

... and can be taught and learned, making it a potentially rapid form of adaptation to change in physical conditions. Anthropologists view culture as not ... biological evolution but as a supplement to it, as the main means of human adaptation to the world. This view of culture as a symbolic system with adaptive ...

Natural selection

... a common ancestor). Additionally, some scientists have theorized that an adaptation which serves to make the organism more adaptable in the future will also ... it is more likely to play an important role in cases where selection for adaptation is continuous. For example, the Red Queen hypothesis suggests that sex ...

Adaptive radiation

... They are : General adaptation. A species that develops a radically new ability can reach new parts of its environment. An example of general adaptation is bird flight. Environmental change. A species that can, in contrast to the other species in the ecosystem, successfully survive in a radically ...

Alternative splicing

... they are based on hitherto functional amino acid subchains. This may allow for a higher probability for a functional new protein. Therefore the adaptation to new environments can be much faster - with fewer generations - than in prokaryotes. This might have been one very important step for multicellular ...

Archaea

... composed mainly of glycerol- ester lipids , whereas archaea have membranes composed of glycerol- ether lipids. These differences may be an adaptation on the part of Archaea to hyperthermophily . Archaeans also have flagella that are notably different in composition and development from the ...

Biodiversity

... people. For others, a broader and more economically defensible definition is that measures should allow to ensure continued possibilities both for adaptation and future use by people, assuring environmental sustainability . As a consequence, biologists argued that this measure is likely to be associated ...

DNA

... the other strand. As a result, the genomes of these viruses are unusually compact for the number of genes they contain, which biologists view as an adaptation . As viewed by topologists Topologists like to note that the juxtaposition of the 3' end of one DNA strand beside the 5' end of the other ...

Drosophila

... 3.2 Reproduction 3.3 Predators 4 External links 5 References Name The term "Drosophila" is a modern scientific Latin adaptation from Greek δρόσος, drsos , " dew ", + φίλος, phlos , "loving" + Latin feminine suffix -a ....

Evolution

... might result in what is known as punctuated equilibrium , the modern interpretation of classic evolutionary theory. Most biologists believe that adaptation occurs through the accumulation of many mutations of small effect. However, macromutation is an alternative process for adaption which involves a ...

Eye

Flagellum

... or not one believes that these prokaryotes constitute a fundamental domain of life (e.g., Woese ), or a just a highly-derived bacterium with heavy adaptation to extremophily , particularly thermophily (e.g., Cavalier-Smith )). The archaeal flagellum is superficially similar to the bacterial (or ...

Genetics

... evolutionary forces: natural selection , genetic drift , mutation and migration . It is the theory that attempts to explain such phenomena as adaptation and speciation . The related subfield of quantitative genetics, which builds on population genetics, aims to predict the response to selection ...

Parthenogenesis

... rapid population growth is important or in stable environments, over the long term sexual reproduction offers a net advantage by allowing more rapid adaptation to changing environments. Asexual lineages can increase their numbers rapidly because (since individuals are always female) everyone can produce ...

Population genetics

... also takes account of population subdivision and population structure in space. As such, it is the theory that attempts to explain such phenomena as adaptation and speciation . Population genetics was a vital ingredient in the modern evolutionary synthesis , its primary founders were Sewall Wright , J. ...

Red Queen

... sex is highly inefficient. One possible explanation for the fact that nearly all vertebrates are sexual is that sex increases the rate at which adaptation can occur. This is for two reasons. First, if an advantageous mutation occurs in an asexual line, it is impossible for that mutation to spread ...

Vestibular system

... from the vestibular system also project to the Cerebellum (where they are used to keep the VOR working, a task usually referred to as Learning or adaptation ) and to different areas in the cortex. The projections to the cortex are spread out over different areas, and their implications are currently not ...
