ANATOMY

Detailed explanation-1: -There are four major variants of speciation: allopatric, peripatric, parapatric, and sympatric. Speciation is how a new kind of plant or animal species is created. Speciation occurs when a group within a species separates from other members of its species and develops its own unique characteristics.

Detailed explanation-2: -Speciation is a macroevolution-ary event as well, because species are the basic unit for measuring large-scale changes in life’s diversity over long spans of time. This dual interpretation of speciation makes sense because once gene flow is sufficiently re-stricted, new species can evolve independently of others.

Detailed explanation-3: -A species is a group of organisms with similar characteristics and can interbreed to give fertile offspring. Speciation is an evolutionary process of the formation of new and distinct species. The species evolve by genetic modification.

Detailed explanation-4: -Which statement about speciation is true? Genetic changes preventing reproduction between formerly interbreeding populations can lead to speciation.
