In ancient times, most of the people have lived their life in fear, dangerously. These people are known as a hominid, which usually lived on the African great land mass. They took their first step along the footway of human evolution and discovered that a stone can be used as a tool or a weapon.

Almost every human at that time faces extreme danger and their life is the struggle for survival which affects their limits of endurance. Their determination to perform seems to be impossible but their feats are like a thread which runs through the pattern of every human destiny and helps them to explain the efforts that were made by various communities in the various parts of the world to adapt to extremely rigorous environmental conditions.

If talking about primitive hunters, who have to think about their prey with their stone axe weapons, and some of the people went the highest peak to make their body physically or mentally fit to travel the space in the past twenty century. The sacrifices of the human beings have always shown their capabilities to adopt all the challenges whether it is the natural environment and to their self-imposed.

Man always has the original and clear ideas which make them look forward and their non-changing behavior makes them master him and their environment make them strong enough to accept any type of deadly challenges.

Their situation defines that they have built themselves to continue doing something which is very painful or difficult to handle for a long period without complaining to anyone. They also adopt the conditions to live life on and under the sea areas in the deserts and tropical regions.

In order to survive like the life, they have lived is fully not acceptable to live with those conditions in which we can’t even happy to live or work. They usually enjoy doing those serious activities without any fear of their lives, while tackling different animals in the polar cold as well hot deserts. These animals are the danger of their lives, they don’t know how to make rid of them and save their life. For that, they have to make standing stock to make their defense from the animals.

Adaptations are physical or behavioral features which help animals and plants survive in their environment. Behavioral adaptations involve changes in the way something acts. Animals (including humans) have control over what they do. An individual conscientiously alters its behavior to adjust to changing environmental conditions. As an example, humans exhibit behavioral adaptations when responding to a hot day in the desert. Physical adaptations involve actual physical or chemical attributes which help a plant or animal survive in its particular environment.

Examples include webbed feet to help such animals as a duck or a frog swim, tiny leaves and a waxy coating to help a plant conserve water, a strong, recurved beak to aid a hawk in ripping meat.

Humans generally make behavioral adaptations in response to heat. Animals as well, often alter their behavior to adjust to intense heat situations. They may seek out shade, drink more water, or become inactive. Besides changing behavior to adapt to a situation, many animals and plant have physical features which allow them to adapt to environmental conditions. Humans living in the desert can and have learned a lot about desert survival from studying the ways native plants and animals have adapted to desert living.

The manner in which they solve their problems was far from perfect. However, if the person or animal concerned survives, and the causal agent of adaptation continues to be active, they usually use several things to live their life such as Feeding, Moving, Protection, Conserving Water, Keeping Water and Keeling Cool. These are the main things that are important for them to live their life and make them good enough to tackle any situation.
