Suppose the Phylogenetic Species Concept (PSC) were preferred over other species concepts, such as the Biological Species Concept (BSC). What would be the implications for: (d) conservation practices under such legal frameworks as the U.S. Endangered Species Act {Ans: The choice of species concept affects conservation biology. Distinct populations that belong to the same species under the BSC can belong to different species under the PSC. Each of these populations could potentially be classified as an endangered species. Also, hybridization between populations has different ramifications, depending on which species concept is used. Because individuals that belong to divergent populations are not considered part of the same species under the PSC, conservation efforts that involve introducing individuals from different populations are less likely to be utilized. The U.S. Endangered Species Act actually provides for protection of "distinct populations," so in many cases it is used to protect organisms that might be considered "sub-species" under the BSC, but would be classified as separate species under the Endangered Species Act.}secondary contact {Ans: In allopatric speciation, isolating mechanisms evolve in geographically separated populations. They play a role in restricting gene flow only if the populations come back together, an event called secondary
