Evolution and Natural Selection Flashcard

Front

What is the ultimate source of genetic variation?

Back

Mutation is the ultimate source of genetic variation, introducing new alleles into a population.

Front

Who developed the Linnaean System of Classification?

Back

Carl Linnaeus developed the Linnaean System of Classification, which organizes living organisms into hierarchical categories.

Front

What is a consequence of low biodiversity?

Back

Increased vulnerability to diseases and pests is a consequence of low biodiversity, as fewer species can lead to ecosystem instability.

Front

What is an example of an adaptation?

Back

A polar bear's white fur is an adaptation that helps it blend into its snowy environment.

Front

What is speciation?

Back

Speciation is the process by which new species are created, often through evolutionary changes.

Front

What is natural selection?

Back

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

Front

What is genetic drift?

Back

Genetic drift is a mechanism of evolution that refers to random changes in allele frequencies in a population.

Front

What is gene flow?

Back

Gene flow is the transfer of genetic material between populations, which can increase genetic diversity.

Front

What is biodiversity?

Back

Biodiversity refers to the variety of life in a particular habitat or ecosystem, including the number of species.

Front

What is an ecosystem service?

Back

Ecosystem services are the benefits that humans receive from ecosystems, such as clean water, pollination, and climate regulation.
