Types of Evolution

Front

What is evolution?

Back

Evolution is the process by which different kinds of living organisms develop and diversify from earlier forms during the history of the earth.

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 the significance of the Galapagos finches in evolutionary studies?

Back

The Galapagos finches are a classic example of adaptive radiation, where different species evolved from a common ancestor to exploit different ecological niches.

Front

What is punctuated equilibrium?

Back

Punctuated equilibrium is a theory in evolutionary biology that proposes that species evolution is marked by isolated episodes of rapid speciation between long periods of little or no change.

Front

What is gradualism?

Back

Gradualism is the theory that evolution occurs slowly and steadily over long periods of time.

Front

What is coevolution?

Back

Coevolution is the process where two or more species influence each other's evolutionary path, often seen in predator-prey relationships.

Front

What is speciation?

Back

Speciation is the evolutionary process by which populations evolve to become distinct species.

Front

What is extinction?

Back

Extinction is the end of an organism or a group of organisms, typically due to environmental changes or loss of habitat.

Front

What does it mean for organisms to have similar DNA sequences?

Back

Organisms with similar DNA sequences are likely to be closely related and share a common ancestor.

Front

What is adaptive radiation?

Back

Adaptive radiation is the process by which organisms diversify rapidly into a wide variety of forms to adapt to different environments.
