ground concepts of natural selection, gene inheritance and anomalies, and adaptation will be important in trying to understand some of the decisions human beings have made. The paper will also assess how the contemporary society has responded to health and adaptation challenges in the bio environment from the perspective of nature and genetics. Human adaptation to natural environment is under constant challenge, prompting a continuous process of biological evolution.
Human being’s capability for adaptation shaped his life on a number of ways. Man evolved to an upright posture, enlarged of brain, ability to make and use tools, emergence of sophisticated mental and social behavior. Human beings later developed technology to change his environment and improve their health. Therefore, nature seems to be having great influence on human survival decisions (BBC 1).
Natural selection as one of the biological factors for human survival was based on the fact that the environment selected the most adaptable organisms to pass on their genetic materials. Natural selection means that organisms that were best adapted survived the harsh conditions of the environment whereas those that were poorly adapted died. Organisms that survived were able to interbreed and therefore, pass on their good genetic traits to their young ones.
As organisms that had survived interbred, the crossing over genetic materials ensured genetic variation and genetic inheritance. Resulting organisms were those ones that constantly evolved and adapted to the environment. This does not mean that environmentally acquired traits were inherited, but that the environment naturally selected organism that were best adapted.
It is said that human evolution took the same process of natural selection where those with good traits survived the harsh environment while those that were poorly adapted died and did not pass their traits to offspring. Inheritance, adaptation and natural selection still matter in the
