The Evolutionary Factors: Why People Are Different

The Evolutionary Factors: Why People Are Different

Authorities say that man comes from common ancestral stock. Diversifications result from repeated and unrepeated changes and processes in the development of the ethic group for essential unity without uniformity.

Creation from the Bible documents from the chapters of Genesis showing us how tribes and groups have developed into bigger territories and nations.

All men belong to the same genus “Homo” and the same species “sapiens.”

From the book, “Man His First Two Million Years,” by Ashley Montagu, “Natural selection, mutation, and isolations are factors, among others, that explain how man differ from each other.”

Charles Darwin says, “As many more individuals of each species are born than can possibly survive; and as, consequently, there is a frequently recurring struggle for existences, it follows that any being, if it vary however slightly in any manner profitable to itself, under the complex and sometimes varying conditions of life, will have a better chance of surviving, and thus be naturally selected.”

Today, natural selection is as adaptive fitness.

Different environments call for different adaptive traits, and the different traits which human beings exhibit are due principally to the fact that man has had to adapt himself to whatever environments he found himself in.

As to mutation, it is any transmissible change in the structure of a hereditary particle or gene, the giant nucleic molecule whose bio-chemical components constitute the biological bases of heredity. Mutations are the raw materials of the evolutionary process.

It is believed that at least one mutations occurs in every human being sometime between conception and death.

For example: Sometimes kinky hair appears in a white family as mutation.

Mutations having adaptive value would rapidly become established in the small populations which were characteristic of early man.

Isolation means separation in any form.

The earth is a large place and upon its surface men have lived in small groups, until this time and are isolated from one another for long periods of time. The isolation is brought about by natural factors such as distance, mountain ranges, rivers, forests, and seas.

This fact makes isolation a factor inseparable from the phenomenon of genetic drift.

How about the pristine forests, and the people around who live there. Such factors will greatly affect how mothers raise their offspring, like the food she feeds them; and how in their adaptive natural selection mutations come, away from the pollution of big factories and industrial wastes.
