This question refers to the same populations of mosquito fish as the previous question. Based on the evidence given in your textbook, can you state that the mosquitofish have speciated into different species, or not?

Build a canal linking the two ponds that permits free movement of mosquitofish, but not of predators.

Explanation:

On the Bahamian island of Andros, mosquitofish populations live in various, now-isolated, freshwater ponds that were once united. Currently, some predator-rich ponds have mosquitofish that can swim in short, fast bursts; other predator-poor ponds have mosquitofish that can swim continuously for a long time. When placed together in the same body of water, the two kinds of female mosquitofish exhibit exclusive breeding preferences.
