Many species of animals make alarm calls, which warn others in their group that a predator is approaching. Alarm calls also attract the atten- tion of the predator, making it more likely that the individual making the call will be eaten. Why might natural selection favor the evolution of alarm calls in a species? How might you test that hypothesis?

Expert Solution

Step 1

Producing an alarm call is a specialised animal behaviour which is intended for safety from the predators. The animals which produce alarm calls, always remain at a risk as these remain at a front foot and much closer to the predator so that they are always exposed to a threat in comparison to other members of the species which lay at a distance from the threat.
