The concept of dividing people into populations or The concept of dividing people into populations or groups based on various sets of characteristics and groups based on various sets of characteristics and beliefs about common ancestry.beliefs about common ancestry.

For many years men have classified the people from different regions by race.

Human racial categories are Human racial categories are based on external features based on external features that we are programmed to that we are programmed to recognize, such as:recognize, such as:

Geographical Importance

Regions and Adaptation

Regions

The human species derives from Africa nearly two million-years-ago.

As Earth went from Pangaea to the form it is today, populations had to migrate to new locations.

The new location the population inhabited forced their bodies to adapt to the new climates they were exposed to.

AdaptationAdaptation

• Variation and physical features result Variation and physical features result mostly from environmental adaptation.mostly from environmental adaptation.

• Variations due to climatic adaptation affect Variations due to climatic adaptation affect exposed parts of the body rather than exposed parts of the body rather than internal structures.internal structures.

• Due to the way climatic adaptations affect our Due to the way climatic adaptations affect our skin color and body shape, populations evolving skin color and body shape, populations evolving from the same type of climates tend to appear from the same type of climates tend to appear similar, while those evolving in different climates similar, while those evolving in different climates tend to vary from one another, such as: tend to vary from one another, such as: 1. Humans that live near the equator tend to

have more darker skin (more melanin) to protect against ultraviolent radiation.

2. Humans that live in much colder environments tend to have a bigger body mass to maintain temperature to prevent damage to internal organs.

Four basic factors that influence genetic change

Mutation - allow an individual to adapt to changing environmental circumstances.

Natural selection - A trait that provides individuals with greater fitness over generations

Random drift - an individual inherits one allele from the mother and one from the father, yet, only one will be passed down to a child. Random genetic drift gene refers to the change in a population’s frequencies resulting from this change factor.

Gene flow and migration - the exchange of genes between populations. Gene flow often occurs as a result of migration

Classification of RaceNow it is very difficult to classify race and determine who belong in which race since many countries have different backgrounds. But most humans would classify humans as:

White African American or black Hispanic Asian American Indian or Alaskan Native Hawaiian or Pacific Islander

White/Caucasian  A person having origins in any of the original peoples of Europe, North Africa, or the Middle East.

Black or African American

A person having origins in any of the black racial groups of Africa (non-Hispanic).

Hispanic/Latino A person who traces his or her origin or descent to Mexico, Puerto Rico, Cuba, Central and South American, and other Spanish cultures, regardless of race.

Definition of Different Races

Asian A person having origins in any of the original peoples of the Far East, Southeast Asia, the Indian Subcontinent. This area includes, for example, Cambodia, China, India, Japan, Korea, Malaysia, Pakistan, the Philippines, Thailand, and Vietnam.

American Indian or Alaskan Native 

A person having origins (ancestry) in any of the original peoples of North and South America (including Central America), and who maintains cultural identification through tribal affiliation or community recognition.

Pacific Islander A person having origins in any of the original peoples of Hawaii, Guam, Samoa, or other Pacific Islands.

Conclusion

• Geographical location and genetics is what differentiates people from one another.

• Race does not exist, it is just the term that we use to classify people from different regions.

•As stated by Dr. J. Craig Venter, head of the Celera Genomics Corporation in Rockville, Md. “Race is a social concept, not a scientific one.”
