The Theory of Natural Selection Explained

The video tutorial explains Darwin's theory of evolution through natural selection, where organisms best adapted to their environment survive and pass on favorable traits. It contrasts this with artificial selection, where humans intentionally breed for desired traits. The video concludes by inviting viewers to explore the components of natural selection further.

What is the main idea behind Darwin's concept of natural selection?

• Survival of the fittest individuals who adapt best to their environment.

• Random survival of individuals regardless of their traits.

• Survival of individuals who are the most intelligent.

• Survival of individuals who are the largest in size.

Which factor primarily influences the selection of traits in natural selection?

• Random chance

• Genetic engineering

• Environmental conditions

• Human intervention

In the context of natural selection, what does 'best adapted' mean?

• Being the most aggressive

• Possessing traits that enhance survival in a specific environment

• Being the largest in size

• Having the most offspring

How does artificial selection differ from natural selection?

• Artificial selection is driven by environmental factors.

• Artificial selection involves human choice in breeding for specific traits.

• Artificial selection is a random process.

• Artificial selection occurs naturally without human intervention.

What is an example of a trait that might be selected for in artificial selection?

• Camouflage in insects

• Sharp teeth in sharks

• Milk production in cows

• Speed in cheetahs
