To determine: The reason that the evolution of alarm calls that are produced by many species of animals are favored by natural selection.

Introduction: The process of natural selection suggests that nature will favor the survival of the fittest among the species of a population. Individuals, who adapt in a way that they are able to face the external environmental conditions and can reproduce to ensure continuity of life on the Earth, will be selected by nature. Many species of animals adapt in various ways in order to get protection from their predators.

Expert Solution

Explanation of Solution

Many species of animals make alarm calls by which they can warn other members in their group about the predators. These organisms also attract the attention of approaching predators, making it more likely that the particular organism making the alarm call will be eaten. These alarm calls is favored by the natural selection because they permit the survival of organisms even in the presence of predators.

Alarm calls or signals promote the survival of organisms by allowing the receivers of alarms to escape from the source of the danger zone. Hence, such alarm calls are favored by the process of natural selection.

Expert Solution

Explanation of Solution

The hypothesis of evolution by natural selection was given by Charles Darwin. This hypothesis suggests that nature will preserve each and every useful variation. Any kind of biological variation either behavioral or physical will be stored by natural selection.

In this case, the hypothesis of natural selection can be tested by observing the evolution of different species of animals producing such defensive signals. These signals favor their survival and hence are conserved by nature.

Students have asked these similar questions

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?

This spectacular animal is a Lesser Bird of Paradise, Paradisea minor, from the highlands of Papua New Guinea. In the context of various evolutionary phenomena, why is this bird confined to New Guinea and two nearby islands? Why would you not expect to find it in the mountains of Borneo? This spectacular tail presumably attracts predators; why hasn't natural selection acted to reduce it or camouflage it?

According to Lamarck’s theory of evolution, organisms change during their lifetime to survive then pass these changes to their offspring. What supports the hypothesis of Lamarck? a. Webbed toes of ducks to quickly move through the water, retractile claws of carnivorous mammals to catch the prey, millipede producing awful smell for self-defense and evolution of short-necked to long-necked giraffe b. Evolution of short-necked to long-necked giraffe, webbed toes of ducks to quickly move through the water, disappearance of limbs in snakes and retractile claws of carnivorous mammals to catch the prey c. Rattlesnake producing venom against predators, jellyfish bioluminescence for intraspecific communication chameleons camouflage to hide from predators and millipede producing awful smell for self-defense d. Disappearance of limbs in snakes, chameleons camouflage to hide from predators, evolution of short-necked to long-necked giraffe and rattlesnake…
