Explanation:

Scientists uncover genetic similarities among species that use sound to navigate ... past studies have relied primarily on researchers' intuition to identify possible genetic players based on prior knowledge of their function .

humans can cause extinction of a species through overharvesting, pollution, habitat destruction, introduction of invasive species (such as new predators and food competitors), overhunting, and other influences. explosive, unsustainable human population growth is an essential cause of the extinction crisis.
