Many theories can never be proven.
Here are a few examples:
-- The moon orbits the Earth.
-- Gravity pulls all masses toward each other.
-- The Earth orbits the sun.
-- Everything is made of atoms and molecules.
-- Atoms are made of protons, neutrons, and electrons.
-- Electrons moving through a wire make electric current.
-- The center of the Earth is molten iron and nickel.
-- The source of the sun's energy is nuclear fusion in its core.
-- Almost all galaxies are moving away from us.
-- The universe is expanding.
None of these statements can be proven. That's why they're not called
Facts or Laws.
It also tells you that some pretty powerful stuff has been done with concepts
that can't be proven. If you want to make an idea look foolish, that doesn't
happen when you say "it's only a theory".
Answer:
Adaption is a gradual process of change or modifications of animal body either physically, structurally or behavioral changes in order to thrive and adjust better in the changing environment for survival.
Explanation:
Adaptation could takes by exhibiting a sort of mimicry to the habitat in which the animal thrive. Also it could takes place by the process of structural changes that blends them well with the environment. Classical Example is the adaptation by Polar bear. In the coolest arctic region, polar bear possesses long white furs with big sized paws and long hair. This help them to blend with white snowy color of environment and the big sized paws prevents them from slipping in ice and also could dig in the ice to take shelter is hostile weather like snowstorm. They have thick layers of fat beneath the skin that keeps them warm. Also they are capable of swimming , in spite of a big body to facilitate their feeding on fishes on arctic sea.
