Explain why scientists believe the Abert’s and Kaibab squirrels are examples of speciation.
Scientists believe the Abert’s and Kaibab squirrels are examples of speciation because they were geographically isolated by the formation of the Grand Canyon. The Abert’s squirrel lives on the South Rim, while the Kaibab squirrel is isolated on the North Rim. Erosion separated the forests, preventing the two populations from interbreeding, which allowed them to develop distinct physical characteristics over time.

Identify the mechanism for isolation described using the drop-down menus. The red-legged frog breeds in ephemeral ponds from January through March. Its relative, the bullfrog, breeds in permanent ponds from late March through May.
Explain the process of evolution through isolation that results in speciation.
How can speciation of plants benefit humans?
Speciation of plants can benefit humans by increasing biodiversity, which allows for the discovery of new plant species. These new species may provide important resources, such as new food sources or unique chemical compounds that can be used to develop new medicines.
In Death Valley, California, there are several ponds that are formed in various areas of the desert. Each pond contains its own species of fish unique to the pond it lives in.
