Effects of Biology on Human Behavior

Introduction

There are several established for centuries and have become traditional for the theoretical science of motivational explanations of human behavior. They can be described as follows: biological and social, innate (genetic) and acquired (resulting from learning), the conscious and the unconscious (Burke, 2011). For each of these areas there are certain theories of motivation. These theories are many, about the same as there are different theories of personality. The biological explanation of the behavior comes from the fact that man is a living creature, body, structure and functioning of which is not fundamentally different from the structure and functioning of many other organisms, the higher animals (Medicinenet.com, 2004). The essence of the explanation lies in the fact that the major sources of human behavior and animal declared to be identical and as such are considered sources of biological needs. It is also argued that the same in humans and animals are the mechanisms of behavior which are regarded as physiological.

Discussion

Life is a degree of complexity different from inorganic matter; one must understand the stage of life as a combination of chemical elements that allow the sensitivity, reproduction and exchange of matter with the environment. It results naturally and safely predictable restructuring process molecular physicochemical held a thousand million years after formation of the Earth. Indeed, the earliest forms of life are linked to environmental and atmospheric conditions on planet Earth. These conditions are nothing special and are likely to have been repeated elsewhere in the universe (Medicinenet.com, 2004). When, through successive molecular synthesis, appeared the first life probably was quickly replicated throughout the planet. The first organisms, which should be extremely simple, were becoming progressively more complex to form the first cells with nuclei.

At first, every single cell performs certain vital functions. After multi-cellular organisms appeared in which each cell or group of cells began to specialize in a specific function. With the passage of time and through the evolutionary process has reached more complex life forms, such as flowering plants or mammals (Medicinenet.com, 2004). As they were emerging forms of living matter, atmospheric conditions on Earth were modified because of the activity of these organisms. This applies to the appearance of atmospheric oxygen generated by the activity of primitive single-celled organisms. An important effect of the presence of oxygen in the atmosphere was the appearance of an ozone layer at high altitudes, which protects the Earth from ultraviolet radiation from the Sun.

Living organisms are complex systems that have the ability to reproduce. The characters and properties of an organism to another by passing the information contained in DNA (deoxyribonucleic acid) in the nucleus of germ cells. The DNA of all living organisms are composed of long chains of macromolecules called nucleotides, which are four different types, which shows that all living things have the same origin. The information contained the DNA, named, genetic code, is determined by the order of the ...
