Natural Selection and Evolution

Front

What is natural selection?

Back

Natural selection is the process by which organisms that are better adapted to their environment tend to survive and reproduce more successfully than others.

Front

What role do mutations play in evolution?

Back

Mutations introduce genetic variation, which is essential for a population to evolve.

Front

Where are genes found in a cell?

Back

Genes are located on chromosomes.

Front

Why is genetic variation important for a population?

Back

Genetic variation allows populations to adapt to changing environments and increases the chances of survival.

Front

What is the outcome of competition in natural selection?

Back

Competition helps determine which variations are more successful, allowing those organisms to survive and reproduce.

Front

Can mutations be inherited?

Back

Yes, mutations can be passed down to offspring if they occur in the germ cells.

Front

What is the difference between natural selection and artificial selection?

Back

Natural selection occurs naturally based on environmental pressures, while artificial selection is the process by which humans breed organisms for specific traits.

Front

What is adaptation?

Back

Adaptation is a trait that helps an organism survive and reproduce in its environment.

Front

What is the significance of the phrase 'survival of the fittest'?

Back

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

Front

What is extinction?

Back

Extinction is the end of an organism or a group of organisms, often due to inability to adapt to changing environments.
