Natural Selection

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 Directional Selection?

Back

Directional selection is a type of natural selection that favors one extreme phenotype over the other phenotypes.

Front

What is Genetic Variability?

Back

Genetic variability refers to the diversity in gene frequencies within a population, often caused by random mutations.

Front

What is a common misconception about evolution?

Back

A common misconception is that individuals can evolve within their lifetime; in reality, evolution occurs at the population level.

Front

What does 'Survival of the Fittest' mean?

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 Biological Fitness?

Back

Biological fitness is defined as the ability of an organism to survive and reproduce in its environment.

Front

What is Stabilizing Selection?

Back

Stabilizing selection is a type of natural selection that favors average phenotypes and reduces variation.

Front

What is Disruptive Selection?

Back

Disruptive selection is a type of natural selection that favors extreme phenotypes over average phenotypes.

Front

What role do Random Mutations play in evolution?

Back

Random mutations introduce new genetic variations, which can be acted upon by natural selection.

Front

How does Environmental Change affect Natural Selection?

Back

Environmental changes can alter the selective pressures on a population, leading to changes in which traits are favored.
