Speciation refers to an evolutionary process of organisms by which over the period of time members of one population evolve to become new species. There are two types of speciations
- Sympatric speciation
- Allopatric speciation
Sympatric speciation is the theory that states that over the period of time some individuals of a population changed due to different stressors such as shelter, food sources, competition while other members of the population remained the same. The group that changed emerged as a new species of population.
Allopatric speciation takes place when members of the population are geographically separated and each member in different geographical conditions evolved into a new species.
