Question

Which of the following must occur for speciation to happen?

Answer 1

The process of speciation takes place within a population when species in a population are reproductively isolated. Speciation is a process that involves the formation of new species in a region.

Further Explanation:

Speciation occurs when one species becomes two or more separate species. Such species are not interbred with each other. Reproductive isolation plays an essential role in the process of speciation.

The different species are found in the different environments and are separated from each other due to geographical and physiological barriers or variations due to different genetic characters.

Different genetic characteristics are due to mutation, reproductive isolation, recombination, genetic drift and natural selection. Whereas, reproductive isolation involves the process of prevention of interbreeding between the members of two separate species. By this way it plays a significant role in maintaining the characters of species and also leads to origin of new species.

Answer 2

Biodiversity depends on a species' ability to reproduce itself. If a species cannot reproduce then it will die out. This depends on the climatic conditions of the region. If there is a natural disaster for example, it will affect a species' ability to reproduce. This reduces the number of diverse species on earth. Biodiversity is the recognised variety of different types of life found on the earth. It also measures the variety of number and variety of plants, animals and other organisms found in different ecosystems.
