Geographic isolation Low geneflow.
Speciation is the process by which new species evolve from existing species. It is necessary for creating and maintaining biodiversity in ecosystems. Without speciation, organisms would not be able to adapt to changing environments and ultimately survive.
Speciation can occur over variable timeframes depending on factors like genetic isolation, selective pressures, and population size. It can range from thousands to millions of years, with some rapid speciation events documented in certain circumstances.
the formation of species
Sympatric speciation refers to the formation of two or more descendant species from a single ancestral species all occupying the same geographic location. Often cited examples of sympatric speciation are found in insects that become dependent on different host plants in the same area.
Speciation is the process by which new species arise. Speciation can be driven by reproductive isolation, which involves barriers that prevent individuals of different populations from interbreeding and producing viable offspring. The formation of these reproductive barriers is a crucial step in speciation as it leads to genetic divergence and ultimately the formation of distinct species.
Because trees died.
put the two groups in different enivorment apex
Factors such as geographic isolation, environmental changes, genetic mutations, and selective pressures can increase the rate of speciation by driving populations to evolve separate traits or behaviors that lead to reproductive isolation.

Allopatric speciation.

Isolation Is necessary for speciation to occur.
Actually it is.
