geographic isolation - involves mountains, rivers, lakes, seas, oceans, dense forests, or other obstacles that bar crossing
Another name for geographic isolation is allopatric isolation. This refers to a type of isolation where populations become reproductively isolated due to physical barriers preventing gene flow between them.
Islands, mountains, deserts, and bodies of water such as oceans or seas can all be landforms that contribute to isolation by creating physical barriers that limit interaction and movement between populations.
there are six types which are below: 1. geographical isolation 2. ecological (habitat) isolation 3. behavioral (ethological) isolation 4. temporal isolation 5. structural (mechanical) isolation 6. gamete mortality (gamete isolation)
physical change
The evolution of the Kaibab squirrel was likely influenced by geographical isolation, specifically caused by the formation of the Grand Canyon. This isolation led to a unique gene pool and adaptations in the Kaibab squirrel population, contributing to their distinct physical characteristics and behaviors.

Three types of isolation involve mating; habitat isolation, mechanical isolation, or sexual isolation.
Another name for geographic isolation is allopatric isolation. This refers to a type of isolation where populations become reproductively isolated due to physical barriers preventing gene flow between them.

Mechanical isolation is a type of reproductive isolation that occurs due to physical barriers preventing mating between members of two different species. This can include differences in size, shape, or other physical characteristics that make mating physically impossible or unlikely. Mechanical isolation helps maintain species boundaries and promotes genetic diversity by preventing interbreeding between species.
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.

Physical Control
Physical Controls
Geographic isolation is when a population is separated by a river/canyon or some impassable terrain. Habitat isolation is when members of a population live in a different type of habitat, say some live in the forest at the bottom of the mountain, while others live further up the mountain. These would then become different populations and evolve to perhaps form two different species.
