How the environment influences human biology

Epigenetics is the vast study of the modifications that occur in gene expressions. There are many causes of gene expression modifications. Scientists have discovered many ways in which genetic structures and endogenous human development are affected. One of the most concerning factors is the environment and the surroundings in which an individual lives. Disease resistance, daily routines, diet, stress, chemicals, and the atmosphere could be included afterward. The main aim of the paper is to discuss how the environment influences human biology.

The organism located in the environment directly affects the development and nourishment of the human and indirectly affects the body’s genes. There are not only external factors that could cause gene modification but also internal factors. In a discussion of the discoveries made and under progress, it is concluded that the environment has a great role in human biology. There are a number of reports and discussions being made that have finalized that the external environment affects the genes and the way the body deals with the disease.

It is observed that light and temperature are the most common factors which influence human biology. Their bodies’ color changes, as well as the body’s metabolism, also work differently, and epigenetics also discusses these things in a similar way.

According to the current studies, the change in DNA is evolutionary, and it takes a century or even more to change. Human biology could be changed in contrast accordingly. According to the analysis, most of the structural changes will result in very slight changes in gene activity. Switching the genes will also result in dramatic effects. Sometimes, the effects are shown and sometimes hidden. There are many reactions of the genes, and the most concern is that the triggering chemical changes would definitely result in the activation of the function of the gene, or maybe the active genes could become silent.

The changes in the environmental, developmental, and social circumstances also result in the changing of a number of RNA functional regulations. Stress is an external factor that is caused by the environment around us. It affects human biology in many ways, but in epigenetics, it affects the brain and life expectancy. A study has shown that individuals who possess more stress have a higher expectancy of living less than comparatively the people who don’t have stress or feel very less about it.

Some slight changes occur in individuals, like a disease or a disability, and the expectation of transferring is relatively higher than that of the diseases that are transferred through contact. It can be explained that the parents who have hemophilia, their children will more likely have the same disease but in a complex form in which they would require continuous blood changes or their life expectancy would be decreased to a few days.

In a nutshell, it can be explained that the environment changes human biology, and the effects can be both beneficial and adverse. There are a number of different ways that are considered the most active in changing human biology, and the most prominent are drugs, chemicals, air, pollution, temperature, adults, stress, weather, and even injuries. So, the final finding of many types of research is that there are many responses of the genes in which the utmost alarm is that the activating chemical changes would definitely result in the initiation of the function of the gene, or the active genes might become silent. The changes in the process of the human gene are lifetime and mostly unconcerned by the individual itself.
