Answer:
- Interruption in the genetic flow between separated groups
- The emergence of new mutations in each of the groups, and their accumulation in time. Slow and gradual differentiation between populations.
- Genetic divergence by natural selection and reproductive isolation
- Prezigotic isolation mechanisms
Explanation:
Allopatric speciation consists of the geographic separation of a continuous genetic background that can give place to two or more new geographically isolated populations. These separations might be due to migration, extinction of geographically intermediate populations, or geological events. In this speciation, some barriers impede genetic interchange, or genetic flux, as the two new groups that are separated can not get together and mate anymore. These barriers might be geographical or ecological.
The process of allopatric speciation involves different steps that affect organisms:
- The emergence of the barrier.
- Interruption in the genetic interchange
- The occurrence of new mutations and their accumulation in time in each population. Slow and gradual differentiation.
- Genetic divergence by natural selection and reproductive isolation makes it impossible for the two groups to mate even if the barrier disappears.
- Prezigotic isolation mechanisms will be favored by selection if occurs a secondary contact between the new species in formation.

Hurricanes, also called tropical cyclones form in seven distinct basins around the world. Some hurricane formation basins are much more active than others. Some tropical cyclone basins also have conditions in which tropical cyclones may occur over longer periods during the year. Most tropical cyclones form from a disturbance in the monsoon trough. The north Atlantic basin is considerably different, as the majority of hurricanes form from easterly waves originating from Africa. Hurricanes and typhoons only can form over large basins of warm water such as an ocean or gulf. This is due to the fact that they need a large amount of energy which is supplied by the heat from the warm ocean waters evaporating into the atmosphere. Hurricanes also occur at least several degrees away from the equator. This is because the Coriolis force is too weak at the equator to generate spin for the hurricane to develop.
