Question

Using your knowledge from the textbook and lecture, discuss why race is a discredited idea in biology. Use examples to make your points.

a. Lack of genetic basis; More genetic diversity within racial groups than between them
b. Social construct; Arbitrary classification based on superficial physical traits
c. Continuous variation; Gradual transitions in traits across populations
d. Interconnected ancestry; No clear-cut boundaries between racial categories

Answer 1

Race is discredited in biology due to the greater genetic diversity within racial groups than between them, its basis as a social construct rather than a biological reality, and the continuous variation and complex distribution of human traits. Organizations and research have since moved away from racial categorization to focus on ancestry, recognizing that race does not have a biological foundation.

Step-by-step explanation:

Discrediting the Biological Concept of Race

In biology, the concept of race has been discredited due to the lack of genetic basis supporting it. It has been demonstrated that there is more genetic variation within supposed racial groups than between them. This fact undermines the biological validity of racial categories and highlights that physical traits such as skin color, hair texture, and eye color do not align with the genetic diversity present within human populations.

Race has also been recognized as a social construct, an arbitrary classification that relies on superficial traits. This is evident when considering how different societies classify race based on different characteristics, which are not consistent across cultures and time. Furthermore, the continuous variation of human traits across populations shows that there are no clear-cut biological categories that correspond to race.

The idea of interconnected ancestry instead of race is gaining ground, where the focus is placed on an individual's ancestry rather than on arbitrary racial distinctions. Historical perspectives show that the concept of race has evolved and often been used to justify discrimination or pseudoscience, such as claims about race-related intelligence differences.

Biological anthropologists affirm that racial categories are not accurately identifiable biologically because all human traits exhibit continuous variation and are distributed in complex patterns globally. The social construction of race has become the predominant understanding, with many social science organizations explicitly rejecting biological explanations of race.
