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 mechanically isolated, behaviorally isolated, temporally isolated
the salamanders developed different reproductive behaviors, and the species were allopatric speciation (the second drop - down menu content is partially shown as allopatric speciation in the ocr, and there is a reset button and a dropdown with the three options as described).

Explanation:

• Behaviorally isolated: The text mentions that salamanders developed different reproductive behaviors. Behavioral isolation occurs when differences in behavior (such as mating rituals) prevent species from interbreeding.
• Allopatric speciation: Allopatric speciation is a mode of speciation where populations of a species become geographically isolated. In this case, some groups of salamanders moved to the east and others to the west, leading to geographical separation. Over time, this separation (along with the development of different reproductive behaviors) led to the formation of new species that could no longer mate.

Answer:

Behaviorally isolated, Allopatric speciation
