Why does polyploidy not cause speciation or even be associated with speciation?
Actually it is.
Speciation without geographic isolation is called what?
Sympatric Speciation develops within the range of the parent population. This type of speciation does not include geographical isolation, and can occur rapidly if a genetic change results in a barrier between the mutants and the parent population.
Speciation occurs during the evolutionary development or phylogeny of a species. In situations can speciation occur?
Speciation can occur through various mechanisms, including allopatric speciation, where populations become geographically isolated and evolve independently, and sympatric speciation, where new species arise within the same geographic area, often due to behavioral or ecological differences. Other forms include parapatric speciation, where populations are adjacent but still diverge due to environmental gradients, and peripatric speciation, a form of allopatric speciation involving a small population at the edge of a larger one. These processes can be driven by factors such as natural selection, genetic drift, and reproductive isolation.
What are the two phases of speciation?
The two phases of speciation are allopatric speciation and sympatric speciation. Allopatric speciation occurs when populations are geographically isolated, leading to genetic divergence due to natural selection, mutation, and genetic drift. In contrast, sympatric speciation happens within the same geographic area, often through mechanisms such as polyploidy in plants or behavioral changes in animals that reduce gene flow. Both processes ultimately result in the formation of new species.
How is symatric speciation similar to allpatric speciation?
Both sympatric and allopatric speciation involve the formation of new species through the genetic isolation of populations. In both cases, reproductive barriers develop that prevent gene flow between populations, leading to divergence and eventually the formation of separate species. The key difference between the two is that sympatric speciation occurs within the same geographic area, while allopatric speciation involves speciation due to geographic isolation.
How do species survive evolve and create speciation?
Species survive, evolve, and create speciation by finding a niche. This means that they find an area where they are able to benefit from food, shelter, and protection from predators.
Speciation caused by change in the course of a river is an example pf divergent speciation?
Allopatric speciation.
The effectiveness of geographical barriers in promoting speciation is related to the?
The effectiveness of geographical barriers in promoting speciation is related to the extent of isolation they create between populations, which limits gene flow. Greater isolation increases the likelihood of genetic divergence between populations and the potential for speciation to occur. Other factors, such as the size of the populations and the duration of isolation, can also influence the effectiveness of geographical barriers in promoting speciation.
Types of Speciation?

What is speciation ?
the formation of species
Complete reproduction isolation is evidence that what has occurred?
speciation
What is necessary for speciation to occur?
Isolation Is necessary for speciation to occur.
Why does polyploidy not cause speciation or even be associated with speciation?
Actually it is.
What is speciation create?
Speciation is the evolutionary process by which populations evolve to become distinct species. It occurs when genetic differences accumulate over time, often due to factors such as geographic isolation, environmental changes, or reproductive barriers. This process can lead to the divergence of populations, resulting in the formation of new species that can no longer interbreed. Overall, speciation contributes to the biodiversity of life on Earth.
