Question

select the correct answer from each drop - down menu. a particular species of salamander was observed in california. some groups of salamanders moved to the east, and a few others moved to the west. over time, the two evolved and were no longer able to mate. this incompatibility was caused by drop - down menu options: mechanically isolated, behaviorally isolated, temporally isolated allopatric speciation drop - down menu. the salamanders developed different reproductive behaviors, and the species were reset button and the drop - down menu as above.

Explanation:

The problem is about salamander speciation. Allopatric speciation occurs when populations are geographically separated. Here, salamanders moved to different regions (east and west), leading to reproductive isolation. The reproductive incompatibility due to different reproductive behaviors is behavioral isolation. So the first blank (type of speciation) is allopatric speciation (already in the dropdown maybe, but the second blank for isolation type: since it's about reproductive behaviors, it's behaviorally isolated. Wait, the dropdown options for isolation: "behaviorally isolated" matches because the isolation is due to different reproductive behaviors. The speciation type here is allopatric (geographic separation causing speciation). So for the isolation part, the correct option is behaviorally isolated.

Answer:

behaviorally isolated
