Evolution isa)Progressive development of raceb)History of racec)History and development of a race along with variationsd)Development of raceCorrect answer is 'C'. Can you explain this answer?

Question

Answer

The term evolution was coined by Herbert Spencer, an English philosopher which means unrolling or unfolding of nature that brings about an orderly change from one form or condition to another resulting in descendants becoming different from ancestors. Thus, it is history and development of race along with variations.

Answer

Evolution is defined as history and developmet of race with variations. The term 'evolution in Biology means gradual changes. It is an excellent working hypothesis to approach the problems of diversity of organisms.

Answer

c)
History and development of a race along with variations

Answer

Evolution refers to the process of change in living organisms over time, resulting in the development of new species. It involves the gradual modification of traits in populations, driven by the mechanisms of variation, heredity, and natural selection. In the context of human evolution, it specifically refers to the changes that have occurred in the human species over millions of years.

The correct answer to the given question is 'C' - History and development of a race along with variations. Let's break down the explanation for this answer:

History and Development of a Race:
- Evolution encompasses the history and development of a race, which refers to a group of individuals with shared characteristics, such as physical features, genetic traits, and cultural attributes.
- Over time, populations of humans have undergone changes in their genetic makeup, resulting in the development of distinct races or ethnic groups.
- These changes occur due to various factors, including genetic mutations, genetic drift, migration, and natural selection.

Variations within a Race:
- Within each race, there are variations in traits and characteristics among individuals.
- These variations can be attributed to genetic diversity within the population, as well as the influence of environmental factors.
- For example, individuals within the same race may differ in terms of skin color, hair texture, facial features, and susceptibility to certain diseases.

Significance of Evolution and Variations:
- The study of human evolution and variations provides insights into our shared ancestry, as well as the unique features that distinguish different races.
- Understanding the genetic and phenotypic variations among races helps in unraveling the complex history of human populations, their migrations, and adaptations to different environments.
- It also enables researchers to study the impact of natural selection on the survival and reproductive success of different traits within populations.

In summary, evolution encompasses the history and development of races, including the variations in traits and characteristics within each race. The study of human evolution and variations is crucial for understanding our species' past, present, and future.
