Does convergent evolution result in speciation?
All evolution that results in increasing genetic divergence between subpopulations may result in speciation. That includes convergent evolution: convergence occurs at the phenotypical level, not at the genetic level.

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.
Which type of evolution requires speciation?
Speciation is the evolutionary process by which new biological species arise.
What are conditions of speciation?
Speciation is when one species evolves into two or more species. There are two mechanisms by which speciation can occur. The first is allopatric speciation. This is where a species is split into two populations by a geographical barrier for an immense period of time. This barrier can be an ocean, a mountain range, a canyon, or anything else that would keep two populations from interbreeding. The second mechanism is called sympatric speciation. This occurs when a new species arises within the parent population. This type of speciation can occur for many reasons. Sometimes a group of the population will search for food in other habitats and they have to adapt to the new challenges. Another possibility is if some of the females start to choose mates based on certain characteristics and others do not. The sexual selection will lead to new characteristics, and a new species in a relative short period of time. The last condition for this mechanism is large genetic variation. Sometimes meiosis, or mitosis does not occur properly and this leads to extra chromosomes in an organism. When this happens, the organism can only reproduce with others that have the same number of chromosomes. This leads to a new species within the parent population.
What is the type of evolution by which organisms evolve differences when they are isolated in different environments?
This type of evolution is known as allopatric speciation, where populations of a species become isolated geographically and evolve independently due to different environmental pressures. Over time, these populations may become distinct species with unique traits and adaptations.

Which type of speciation occurred among galapagos islands finches?
allopatric speciation
Two populations that are separated by a mountain range can no longer interbreed to produce fertile offspring this is an example of what speciation?
This is an example of geographic isolation, a type of allopatric speciation where physical barriers prevent gene flow between populations, leading to the accumulation of genetic differences and eventually reproductive isolation.
What type of speciation occurs when new species arise as a result of geographic isolation?
When a certain species is divided up into two or more separate populations (geographically, for example) they continue to evolve (via natural selection) and over time the two (or more) populations will be so different from each other that they will not be able to reproduce, and will fit the criteria of different species.
