Question

FILL IN THE BLANK

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 (A. allopatric speciation, B. convergent evolution, C. coevolution) . The salamanders developed different reproductive behaviors, and the species were (A. mechanically isolate, B. behaviorally isolated, C. temporally isolated) .

Answer 1

Okay question 1. B or C I'd ask NICOLEGOLFLOVER

Answer 2

Answer : The correct answer is -

1) A. allopatric speciation.

2)B. behaviorally isolated.

Allopatric speciation can be described as formation of new species when a biological population belonging to one species becomes geographically isolated and no gene flow occurs between the two during the course of evolution.

As per the given information in the question, a group of salamander population moved to east and another to west, which later evolved into two different population as they were unable to mate.

Thue, it represents allopatric speciation.

As the salamanders developed different reproductive behaviors, therefore it indicates behavior isolation, suggesting that they will perform different mating rituals.
