The Earth has a history of sharp climactic shifts.
Each results in extinctions, a reduction in overall biomass and increased pressures to adapt to the altered environment. The crises resolve to periods where biomass increases, opportunities in novel and open niches become available, and new species have an opportunity to expand their populations in the more friendly environment ---- ur welcome
What else can I help you with?
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.
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.
Process in which isolated populations of the same species become new species is called?
In Sympathetic Speciation, a species evolves into a new species without any barriers that separate the populations.In Allopatric Speciation, a population divided by a barrier, each population evolves separately, and eventually two populations cannot successfully interbreed.
