Question

describe an environmental factor that could influence natural selection and decrease genetic diversity. pick a specific example to illustrate your point.

Explanation:

One environmental factor is habitat destruction. For example, deforestation reduces the living space for many species. Trees provide food, shelter, and breeding grounds. When forests are cut down, species that depend on them may face intense competition. Only those that can adapt (e.g., some birds may shift to smaller remaining trees or nearby habitats if possible) will survive. Over time, this can lead to a loss of genetic diversity as many specialized genetic traits (e.g., those related to specific tree - dwelling behaviors or adaptations to forest microclimates) are lost.

Answer:

Habitat destruction (e.g., deforestation) can influence natural selection and decrease genetic diversity.
