How do adaptations arise?

Adaptation – the adaptation of the body to any condition of life. The body is a smart creature, so to speak, if a stressful situation arises or something needs to be developed, it does it. If a person does not have enough food, he turns on an energy-saving mode and breaks down fats or sugar in the body into carbohydrates, if the animal needs claws for its existence, they will. So the mole has legs that allow it to dig. The rabbit turns white at the onset of winter for camouflage. If you take a plant, it will turn towards the light and it is possible that its cells (tissues) can deform, the same principle is used to obtain the forms of watermelons, which are closed in a box and its cells are deformed.
