After many changes evolve in a group of animals, individuals of that group can no longer mate with the rest of the species that remain unchanged. That is the definition of species: individuals that are able to breed among themselves but are not able to breed with other species.
When a group of individuals is separated from the rest of their species for a long time, the individuals can evolve different traits. The longer the group is isolated from the rest of the species, the more likely it will evolve into a new species. One example of this has been seen in fish species in the lakes of Switzerland, Great Britain, and Scandinavia. Almost every lake has different forms, believed to have evolved from one species.

∙ 13y agoThe term for this is allopatric speciation, where a population splits into two geographically isolated populations The isolated populations undergo genotypic and/or phenotypic divergence overtime. Examples of this are: the groups become subjected to dissimilar selective pressures, they undergo their own genetic drift, and different mutations arise in the two populations. When the populations come back into contact, they have evolved such that they are reproductively isolated and are no longer capable of exchanging genes.

What can result from long term isolation?
Long term isolation can cause new species to form if the isolation has been over a very long time.
The formation of a new species can result from what?
Mutation, isolation and natural selection. Google allopatric speciation.
What explains how a new species will originate once a group of individuals can no longer interbreed with other individuals?
reproductive isolation.Reproductive isolation
What is The theory that most new species form when small populations became isolated?
The idea that new species form when isolated from the parent group is called genetic drift. The isolation can be as small as a few miles to thousands of miles.
Why can isolation cause differences in species and possibly to a new species?
i dont know ask your teacher!!
How might the isolation of a group result in a new species?
a new species might form when a group of individuals remains sparated from the rest of its species long enough to accumulate different traits
What can result from long term isolation?
Long term isolation can cause new species to form if the isolation has been over a very long time.
What is one way species form?
Geographic isolation is a way in which a new species can form. Isolation over a long enough period of time can result in a species evolving to have different traits.
What is the biological term when new species form as a result of geogical isolation?
Alopatric speciation.
What are three ways isolation occur?
1. When new species form.2. When a group is separated from the rest of its species.3. When members of the isolated group can no longer mate with the rest of species.
The formation of new species Can result from what?
Mutation, isolation and natural selection. Google allopatric speciation.
The formation of a new species can result from what?
Mutation, isolation and natural selection. Google allopatric speciation.
What explains how a new species will originate once a group of individuals can no longer interbreed with other individuals?
reproductive isolation.Reproductive isolation
How do isolation and natural selection result in new species?
Isolation prevents mating between the populations and in time different mutations will accumulate in each population so much that they will no longer be able to mate. The inability to interbreed is one of the definitions of different species.
How is reproductive isolation related to the formation of new species?
Speciation would not be possible without reproductive isolation. We define species today as a group of organisms capable of reproducing fertile offspring. If there was no reproductive isolation, it means that the organisms are constantly interbreeding, mixing their genes, thus unable to become two mutually reproductively exclusive groups, or different species.
How can the isolation lead to the formation of new species?
Once a group becomes isolated, members of the isolated group mutate to adapt to their new environment. For birds, this may mean new colors, food preferences and so on, which make it entirely different from the original. Once a group becomes isolated, members of the isolated group can no longer mate with the rest of the species.
What is The theory that most new species form when small populations became isolated?
The idea that new species form when isolated from the parent group is called genetic drift. The isolation can be as small as a few miles to thousands of miles.
