Natural Selection

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 produce more offspring.

Front

What role do mutations play in evolution?

Back

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

Front

Which organisms are most likely to survive in a changing environment?

Back

The best adapted organisms are most likely to survive.

Front

Do organisms consciously decide to evolve?

Back

No, organisms do not decide to evolve; they change due to natural selection.

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence of an organism.

Front

What is a population in biological terms?

Back

A population is a group of individuals of the same species living in a specific area.

Front

What is genetic variation?

Back

Genetic variation refers to the differences in DNA among individuals within a population.

Front

How does natural selection lead to evolution?

Back

Natural selection leads to evolution by favoring traits that enhance survival and reproduction, gradually changing the population over generations.

Front

What is adaptation?

Back

Adaptation is a trait that increases an organism's chances of survival and reproduction in a specific environment.

Front

What is the difference between genotype and phenotype?

Back

Genotype is the genetic makeup of an organism, while phenotype is the observable physical characteristics.
