What is the seventh key concept?
The number of individuals with each trait in a population.
What is distribution?
The number of individuals with each trait in a population can change over time.
What is the second key concept?

What is the ninth key concept?
A specific characteristic of an individual organism.
What is trait?
Over many generations, individuals with adaptive traits become more common in a population, while individuals with non-adaptive traits become less common.
What is the third key concept?
The process by which the distribution of traits in a population changes over many generations.
What is natural selection?
Mutations are changes to genes that can lead to changes to protein molecules, which can result in changes to traits.
What is the tenth key concept?
A group of individuals born and living at about the same time.
What is generation?
The traits that exist in a population determine which traits can become more common over many generations.
What is the fourth key concept?
A trait that makes it less likely that an individual will survive in a specific environment.
What is non-adaptive trait?
Individuals inherit their genes from their parents. Genes, and therefore traits, in a population are passed down from generation to generation.
What is the eighth key concept?
A graph that uses a bar to show how characteristics or values are distributed.
What is histogram?
Whether or not a trait is adaptive depends on the environment.
What is the fifth key concpet?
A trait that makes it more likely that an individual will survive in a specific environment.
What is adaptive trait?
A new trait will only become more common in a population if it is adaptive.
What is the last key concept?
