The new species is one of the things that characterizes specialization in new areas such as the recently formed island. The climate is the other.
This process is called speciation. It occurs when isolated populations evolve independently, accumulating different genetic changes, ultimately leading to the formation of new species that are unable to interbreed.
Speciation without geographic isolation is called sympatric speciation. This type of speciation occurs when new species evolve from a common ancestor in the same geographic area. It is often driven by other factors such as ecological or reproductive isolation.
Divergence
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.
The new species is one of the things that characterizes specialization in new areas such as the recently formed island. The climate is the other.
Speciation in new areas, like recently formed islands, is often driven by geographic isolation and genetic drift. Small founder populations can lead to rapid divergence in gene pools, creating new species adapted to the unique island environment. Natural selection and genetic mutations also play a role in speciation on new islands.
Rapid speciation occurs as populations adapt to the environment. (Novanet)
They both are mechanisms by which new species arise
Speciation
instantaneous speciation
Speciation is the evolutionary process by which new biological species arise.
The development of a new species through evolution is called speciation.
Speciation
This concept is called allopactric speciation.
Allopatric and sympatric speciation are both methods by which new species arise. However, allopatric speciation is when species interbreed. Sympatric speciation is when several new species arise from a common ancestor.
