WebPolyploids are considered a new species because the occurrence of a whole genome duplication imposes post-zygotic barriers, which enable reproductive isolation between parent populations and hybrid offspring. Polyploids can arise through single step mutations or through triploid bridges. WebMay 20, 2024 · Today, it is known to be just one of several mechanisms by which life evolves. For example, a phenomenon known as genetic drift can also cause species to evolve. In genetic drift, some organisms —purely by chance—produce more offspring than would be expected.
WebA species is a group of organisms that can reproduce with one another to produce fertile offspring and is reproductively isolated from other organisms. Speciation can be driven by evolution, which ... WebA species is a group of organisms able to interbreed and produce fertile offspring.

WebApr 11, 2024 · “@Anthrofuentes @FondOfBeetles @SwipeWright There are species where typical forces of sexual selection are reversed, where selection is stronger for females for example, but this does not mean that the biological meaning of the sexes is reversed. There are still the males that produce the sperm and the females the eggs.” WebBiologists sometimes define two types of evolution based on scale: Macroevolution, which refers to large-scale changes that occur over extended time periods, such as the formation of new species and groups. …
WebEvolution is a biological process. It is how living things change over time and how new species develop.
