  1. Sympatric Speciation
    • According to 2 sources
    Sympatric Speciation- The type of speciation when there are no physical barriers to prevent any members of a species from mating with one another. All members are in close proximity to one another in this type of speciation. This type of speciation is common in herbivore insects when a new plant is introduced into a geographical range of species.
    Sympatric Speciation: This type of speciation occurs between populations occupying the same geographic range. This type of speciation is common in herbivore insects when a new plant is introduced into a geographic range of species. Parapatric Speciation: It separates adjacent populations.

    How do herbivores speciate?
    When herbivore insects begin feeding and mating on a new plant or when a new plant is introduced within the species’ geographical range, this mechanism of speciation is prevalent. vii. The gene flow between species that specialise in a particular plant is then decreased, potentially leading to the emergence of new species. viii.

    What are some examples of when speciation might occur?
    Speciation occurs when a group within a species separates from other members of its species and develops its own unique characteristics. The demands of a different environment or the characteristics of the members of the new group will differentiate the new species from their ancestors. An example of speciation is the Galápagos finch.

    What is the initial phase in the process of speciation?
    The initial phase in the process of speciation is the isolation of a subpopulation of a species, which can occur physically (allotropic speciation) or genetically (sympatric speciation). Once the population is divided, a subpopulation of a species develops as a result of a slow accumulation of tiny genetic changes.
