The concept of evolution
Evolution affects all life forms on the planet and is characterized by genes' ability to change their structure during the adaptation processes to the living environment. When some changes in the environment occur, they instantly cause some changes in the DNA. So, if environment conditions are not lethal for living organisms, then the genes start changing their structure progressively, while being affected by environmental factors and in that way organisms develop new features, which help them to survive in the new environment more effectively. The speed at which those genetic changes occur depends on the benevolence of environment conditions. The more favorable those conditions are, the faster adaptation goes. The brain is adapted to accumulate information aspects in cerebral cortex, where they are converted to memory aspects because during the existence and evolution of humans and other life forms their living environment was constantly changing and that forced the organisms to change too in order to adapt to the new conditions because every new environment contains different elements. Some of them are doing positive effects to organisms or act as a direct energy source and others are harmful (cause disturbances in using the direct energy source or cause destruction of it).
