Speciation is the evolution of new species from existing species and that is what has happened here. If a species was split up due to some sort of natural disaster, each party would evolve on their own because of the isolation. They will adapt to the new environment and eventually develop a new gene pool - this is when a new species has developed.

Isolation of groups can lead to speciation when it results in reproductive barriers that prevent gene flow between populations. This can occur through geographic isolation (allopatric speciation), ecological isolation (sympatric speciation), or behavioral isolation. Over time, genetic divergence can accumulate, leading to the formation of new species.

∙ 12y agoThere are two types of isolation- reproductive isolation and geographical isolation. The isolation that you are talking about is called geographical isolation e.g. if members of the same species get stranded on two different islands. At first as these organisms are all members of the same species, they will have one single gene pool. The climate on the two islands is very different and so the individuals on each island will need to adapt to the climate on that island so there will be a change in the alleles. Then say somehow the two islands the come together and the individuals of the two species are reunited but even though they are reunited, they can't breed with each other because they now have two separate gene pools due to change in alleles, they have evolved into two different species because they had to adapt to different conditions. Speciation is the evolution of new species from existing species and that is what has happened here.

What would most likely increase the rate of speciation in a population?
Factors such as geographic isolation, environmental changes, genetic mutations, and selective pressures can increase the rate of speciation by driving populations to evolve separate traits or behaviors that lead to reproductive isolation.
How does geographic isolation lead to speciation and adaptive radiation?
Geographic isolation restricts gene flow between populations, leading to genetic divergence over time. This can result in the development of reproductive barriers, ultimately leading to speciation. When a new habitat becomes available to colonize, such as through geographic isolation, it can lead to adaptive radiation as different species evolve to exploit available resources in that new environment.
Two populations that are sperated by a mountain range can no longer interbreed to produce fertile offspring this is an example of?
This is an example of geographic isolation, where a physical barrier like a mountain range separates populations, preventing gene flow and leading to reproductive isolation. Over time, this can result in the populations evolving independently and potentially becoming distinct species.
How can populations become reproductively isolated?
Populations can become reproductively isolated through mechanisms such as geographic isolation (resulting in allopatric speciation), behavioral differences (resulting in prezygotic isolation), or genetic changes that lead to incompatibility between individuals (resulting in postzygotic isolation). These barriers prevent gene flow between populations, leading to their divergence and ultimately speciation.
Can occur when part of a population of a species becomes separated from the remainder they may over time evolve different characteristics from the parent population?
This is known as allopatric speciation. It occurs when a physical barrier separates a population, leading to genetic isolation and ultimately the development of different traits. Over time, this can result in the formation of a new species.
Speciation that results from geographical isolation that leads to reproductive isolation?
Allopactric ( other country ) speciation.
What is necessary for speciation to occur?
Isolation Is necessary for speciation to occur.
Complete reproduction isolation is evidence that what has occurred?
speciation
How is speciation and reproductive isolation related?
Reproductive isolation is a type of speciation. Reproductive isolation is when a species divides forming two subspecies, due to different mating periods.
Allopatric speciation requires?
geographic isolation.
Polyploid speciation is perhaps the fastest form of speciation because it results in immediate?
reproductive isolation
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.
Sympatric speciation specifically excludes?
Geographic Isolation
Which increase speciation?
Geographic isolation Low geneflow.
How are spec spec creation and reproductive isolation related?
How are speciation and reproductive isolation relator
What are the two main types of isolation?
That would be geographic isolation and reproductive isolation. Both could lead to speciation.
What is the is the first step in allopatric speciation?
physical isolation of two populations
