Question

What are the advantages of Evolution?

Answer 1

Hint: The history of life forms and their growth is studied under the term called evolution. Evolution is a concept where all life forms are categorized according to their days on earth, determining how old they are. Different animals have different ages. As we discussed the evolution and evolutionary concepts, each animal holds a specific age or period from which they have been born or came into life.

Complete answer:
Mammals and birds of hotter areas undergo aestivation in summer; aestivation is another term used for hibernation. As it referred to the hiding of animals in order to survive the adverse effects of climate. During summers mammals and birds are hidden with all the necessary requirements to some suitable place and remain there until the climate changes.
Evolution has several advantages despite always counting the disadvantages-produces of variation. Variation is the change occurring in an individual which is inherited from the parent generation. It can be a survival advantage where chromosomes change, likely to decrease the effect of syndrome or any other defect.
A disease or any change in environment also can affect the person. Human evolution in nature possesses a cognitive relationship. Nature has capabilities to acquire and understand the human body. In return the human body changes its diet and adapts according to nature to survive. Human body’s also show defenses if the variation turns out to be harmful.
Natural selection shows traits which are transmitted through generations and it can lead to speciation and the new species which evolve during this period show different characteristics from the older individuals or groups. They have adapted to new habitats and can also show advantage in thermoregulation and developmental changes.

Note:
Species of larger size are found in colder environments and species of smaller size are found in warmer regions – organisms at higher altitudes should be larger and thicker than those closer to the equator to have a better conservation of heat. This is called Bergmann's rule. As land animals have limbs to walk, they are required to maintain body-weight. And aquatic creatures have gliding and swimming characteristics.
