Genetic evolution: Evolution is natural gradual process of development in accordance with the needs of natural world. As environment in the nature transforms, it demands only species to survive that can fit. In other sense is modification process to survive in the natural world is genetic evolution. Environmental process by occurrence changes condition for species, evolution process acts accordingly for existence. Reacts and modifies shapes to fit in the environment. Environment initiates species to react for its fittingness. All genuses do not survive due to incompatibility; on the other hand which is strong to endure can survive or modify selves to fit with. Nature wants something new and evolution given it.
History & social evolution: Evolutionary process of cultures and religions enhance its population to rise and go along. This process of evolution passes from individuals to entire society to make strong society. Those societies which are not strong either subside or merge with the strong one. This way the civilization prolongs till reaches to its highest point and starts decomposing as the rule of universe is extreme of positive gives birth to negative and extreme of negative gives birth to positive. Means its extreme starts rotting and begin to collapse. Can be a cause by either natural (overheating earth, earth quack, famine etc
or human created disaster, deforestation converting to desert, polluting nature to disturb ecosystem, extreme practices. Its extreme practices to maintain its civilization gives birth to new form of revolution to start new liberal community thus the old one becomes history of civilization and new one is the evolutionary form. Present civilization will also have the same consequence; present affect of this civilization is extreme poverty, rotten attitude of religions, and extremism etc; are changing the environment when reaches to extreme will begin revolution to evolve. Behavioral evolution: Evolution from ape to human resulted by experiments to survive in competition with natural law. Behavioral evolution is a process of reaction to occurrence that finds ways to advance to live with. Genetic character of two legged species are more intelligent among all species, for example, among four legged cat species are sharper, is due to inbuilt genetic character. Human creatures reacted faster than other species that developed them to form societies. Variation of behavior of members in the group developed intelligence for protection, resistance and etc;
Evolution is a process of fight with circumstancesEvolution progresses is when striving for survival during crisis. Water shortage in Saudi Arabia evolved a process to refine sea water to drinking standard this is a process of evolution that reacted to crisis to develop alternate.
Individual behavior evolution: Each individual has its own behavior and practices in accordance with the negative positive factors in self. Environment around accelerates behavior to evolve; One become Hitler and one Gandhi both went through aggression may be of different condition. There is reason behind such occurrences as the percentage of negative positive factors reacts to the environment. With having negative factor could catch negative portion of environment and behave negative on the other hand even in negative environment some people behave positive because positive factors reacted to negative environment around and evolved to refuse to go along with. Environment is booster to behavior.
We are all spirits (ATMA) use body to perform and give back to earth, gather energy from environment to give back for future generation.
