The definition Biological evolution, simply put, is descent with inherited modification. This definition encompasses everything from small-scale evolution (for example, changes in the frequency of different gene versions in a population from one generation to the next) to large-scale evolution (for example, the descent of different species from a shared ancestor over …

Evolution definition, any process of formation or growth; development: the evolution of a language; the evolution of the airplane. See more.

Divergent evolution or divergent selection is the accumulation of differences between closely related populations within a species, leading to speciation.Divergent evolution is typically exhibited when two populations become separated by a geographic barrier (such as in allopatric or peripatric speciation) and experience different selective pressures that drive adaptations to …

crustacean, any member of the subphylum Crustacea (phylum Arthropoda), a group of invertebrate animals consisting of some 45,000 species distributed worldwide. Crabs, lobsters, shrimps, and wood lice are among the best-known crustaceans, but the group also includes an enormous variety of other forms without popular names. Crustaceans are generally aquatic …

Organic Evolution Definition “Changes in the genetic makeup of species in a population as a result of responding to environmental changes is organic evolution” ... developmental biology, etc. The theory highlighted the main points as per Brian Richmond, which are – “All life on earth is connected and related to each other” and ...

Evolution and diversity result from the interactions between organisms and their environments and the consequences of these interactions over long periods of time. Organisms continually adapt to their environments, and the diversity of environments that exists promotes a diversity of organisms adapted to them. In recent years, new techniques and approaches have opened …

Molecular evolution is the process of change in the sequence composition of cellular molecules such as DNA, RNA, and proteins across generations. The field of molecular evolution uses principles of evolutionary biology and population genetics to explain patterns in these changes. Major topics in molecular evolution concern the rates and impacts of single nucleotide …
