How do organisms 'win' at natural selection?

Back

Organisms 'win' at natural selection by surviving and reproducing, passing on their advantageous traits to the next generation.

Front

What is genetic drift?

Back

Genetic drift is a mechanism of evolution that refers to random changes in the frequency of alleles in a population, often having a more significant effect in small populations.

Front

What is natural selection?

Back

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

Front

What is an adaptation?

Back

An adaptation is a trait that helps an organism survive in its environment, such as camouflage or specialized feeding habits.

Front

What role does variation play in natural selection?

Back

Variation provides the raw material for natural selection; individuals with beneficial variations are more likely to survive and reproduce.

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 the significance of Darwin's theory of natural selection?

Back

Darwin's theory explains how species evolve over time through the survival of individuals with favorable traits.

Front

What is the term for a change in a species over time?

Back

Evolution.

Front

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

Back

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