An archipelago is basically a group of islands. Speciation according to the Biological Species Concept by Ernest Mayr, is -- populations whose members can interbreed and produce viable, fertile offspring. For example, the Galapagos finches studied by Charles Darwin. Some live on different parts of the archipelago and so have different features, adapting to their environment. These different feature obviously get passed down and are more frequent in future populations because those finches with this specific adaptation lived and reproduced better. So since there are different islands, there are different finch speciation and so the geographic isolation promotes speciation.

What process often begins by a portion of a population becoming physically or geographically isolated speciation or selective breeding or genetic change or resistiance?

Speciation often begins with a portion of a population becoming physically or geographically isolated. This isolation can promote genetic changes over time, leading to the development of new species. Selective breeding and resistance can also play a role in shaping the genetic diversity of a population but are not direct drivers of speciation through isolation.


Is necessary for the process of speciation?

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.


What best describes how long it usually takes for speciation to occur?

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.


What is speciation ?

the formation of species


Speciation that begins as members of a population occupy different ecological zones within the same geographical area is?

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.

What factors have contributed to the adaptive radiation of the thousands of endemic species of the Hawaiian Archipelago?

The adaptive radiation of endemic species in the Hawaiian Archipelago has been driven by several key factors. First, the islands' isolation provides a unique environment with limited competition and predators, allowing species to evolve independently. Second, the diverse habitats created by varied climates, elevations, and geological features promote niche differentiation. Lastly, the presence of various ecological opportunities, such as adaptive traits that allow species to exploit different resources, has facilitated rapid speciation and diversification.
