Preservation of species diversity, Biology

Q. Preservation of species diversity?

Genetic diversity is, thus, important for the preservation of species diversity, and hence biological diversity. A knowledge of the variability of genes also allows us to understand how closely individuals or species are related to each other. Genetic diversity between species becomes greater with increasing distance in the relationship of species. Consequently more distantly related species will represent a higher range of genetic diversity than closely related species. Genetic variability responsible for these different traits, interacts with local environmental conditions to determine the extent to which populations can adopt to environmental changes. Isolated population such as those on ocean: islands or in small patches of habitats cut off from the surrounding environment tend to have less genetic variation, hence more susceptible to extinction.
