Scientists have found that the existing populations of a certain species of amphibian are small in number, lacking in genetic diversity, and separated from each other by wide areas of dry land. Which of the
following human actions is most likely to improve the long-term survival of the amphibians?
?
A
Cloning the largest individuals to counteract the effects of aggressive predation
Reducing the population size by one-fifth to decrease competition for limited resources
©
Constructing a dam and irrigation system to control flooding
D
Building ponds in the areas of dry land to promote interbreeding between the separated populations

Genetic diversity is the raw matter for evolution. Any action concerned to increase the genetic diversity of natural populations will invariably help to increase the adaptive fitness of such populations.

  • Genetic diversity can be defined as the gene pool or amount of genetic information of natural populations and species.

  • Natural selection act by selecting those individuals genetically better adapted, which are capable of surviving and reproducing (i.e., the adaptive fitness) in a given environment.

  • It is well known that interbreeding between natural populations can increase genetic diversity, thereby increasing the likelihood of facing environmental changes (thus increasing the likelihood of survival and reproduction).

  • In consequence, the human actions that are most likely to improve the long-term survival of the amphibians will be building ponds in the areas of dry land to promote interbreeding between the separated populations (Option D).
