Evolution and Natural Selection

Front

What is evolution?

Back

Evolution is the process by which different kinds of living organisms develop and change over time through genetic variation and natural selection.

Front

What is natural selection?

Back

Natural selection is the process where organisms better adapted to their environment tend to survive and produce more offspring.

Front

What is an adaptation?

Back

An adaptation is an inherited trait that enhances an organism's ability to survive and reproduce in its environment.

Front

What are heritable traits?

Back

Heritable traits are characteristics that can be passed from parents to their offspring through genes.

Front

Who proposed the theory of evolution by natural selection?

Back

Charles Darwin proposed the theory of evolution by natural selection.

Front

What is the significance of the peppered moth in studying evolution?

Back

The peppered moth is significant because its color variation demonstrates natural selection in response to environmental changes.

Front

What role do mutations play in evolution?

Back

Mutations are changes in DNA that can create new traits, which may be beneficial, harmful, or neutral, contributing to evolution.

Front

What is the difference between adaptation and acclimatization?

Back

Adaptation is a genetic change over generations, while acclimatization is a short-term physiological adjustment to environmental changes.

Front

What is the concept of 'survival of the fittest'?

Back

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

Front

What is selective pressure?

Back

Selective pressure is an environmental factor that influences which individuals survive and reproduce, driving natural selection.
