Vor 5 Tagen · evolution, theory in biology postulating that the various types of plants, animals, and other living things on Earth have their origin in other preexisting types and that the distinguishable differences are due to modifications in successive generations.
Vor 5 Tagen · Our contrast of recent and long-term gene flow shows that regions of low recent hybridisation are indeed enriched for long-term barriers which maintain divergence between these hybridising sister species. This paves the way for future analysis of the evolution of reproductive isolation along the speciation continuum. Author summary Efforts to ...
Vor 4 Tagen · Genetic drift is a mechanism of evolution characterized by random fluctuations in the frequency of a particular version of a gene (allele) in a population. Though it primarily affects small, isolated populations, the effects of genetic drift can be strong, sometimes causing traits to become overwhelmingly frequent or to disappear ...
Vor 5 Tagen · Evolution is the process of heritable change in populations of organisms over multiple generations. Evolutionary biology is the study of this process, which can occur through mechanisms...
Vor 3 Tagen · Social and environmental transmission spread different sets of gut microbes in wild mice. Long-term high-resolution data on social relationships, space use and microhabitat in a wild population of...
Vor 3 Tagen · Microbial mats of coexisting bacteria and archaea were the dominant form of life in the early Archean eon, and many of the major steps in early evolution are thought to have taken place in this environment.
Vor 3 Tagen · In addition, a null correlation between geographic and genetic distances among populations (R2 = 0.007; p = 0.02) was detected by the Mantel test, indicating no significant isolation by distance. These findings are novel and have a great impact to begin planning conservation strategies for A. deceptrix considering that it is an endemic species, threatened by anthropogenic activity and has ...
