Theory of Evolution and Natural Selection

Front

What is the Theory of Evolution?

Back

The Theory of Evolution explains how species change over time through processes like natural selection and genetic variation.

Front

What is natural selection?

Back

Natural selection is the process where organisms with traits better suited to their environment are more likely to survive and reproduce.

Front

What are adaptations?

Back

Adaptations are traits that help an organism survive and thrive in its environment.

What is an example of an adaptation in Arctic Hares?

Back

The white fur of Arctic Hares is an adaptation that helps them blend in with their snowy environment, making it harder for predators to see them.

Front

What are inherited traits?

Back

Inherited traits are characteristics passed down from parents to offspring through genes.

Front

What are acquired traits?

Back

Acquired traits are characteristics that an organism develops over its lifetime due to environmental influences, not genetic inheritance.

Front

How do environments influence evolution?

Back

Environments provide different challenges and resources, leading to the development of specific traits in organisms that help them survive.

Front

What does 'survival of the fittest' mean?

Back

'Survival of the fittest' refers to the idea that individuals best adapted to their environment are more likely to survive and reproduce.

Front

What role does variation play in evolution?

Back

Variation among individuals in a population is essential for natural selection, as it provides the raw material for evolution.

What is the significance of Darwin's finches?

Back

Darwin's finches are a classic example of adaptive radiation, where different species evolved from a common ancestor to exploit different food sources.
