Natural Selection

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

An adaptation is a characteristic or trait that helps an organism survive in its environment.

The first step in protein synthesis is the conversion of DNA to RNA.

FALSE: Animals do not choose how they adapt; adaptations occur through natural selection.

Fish is NOT an adaptation; it is a type of organism.

Genetic drift is a mechanism of evolution that refers to random changes in the frequency of alleles in a population.

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

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

Fitness refers to an organism's ability to survive and reproduce in its environment.

Variation is crucial for natural selection as it provides the raw material for evolution; without variation, all individuals would be identical.
