Patterns of Evolution vocabulary

What is macro evolution?

• large changes overtime that occur between species

• small changes overtime that occur within a species

• large changes overtime that occur within a species

• small changes overtime that occur between species

What is background extinction?

• long periods of little or no change are interrupted by periods of rapid change

• process by which two species evolve in response to change in each other over time

• extinction that affects huge numbers of species over a relatively short time

• extinction caused by the slow process of natural selection

What is speciation?

• The development of new species from a pre-existing species

• Two species evolve to become more similar over time

• The idea that evolution occurs slowly and gradually

• None of the above

What is gradualism?

• Idea that long period of little or no change are interrupted by short periods of rapid change

• The idea that evolution occurs slowly and gradually

• Single species evolve into diverse species that live in different ways

• Process in which unrelated species come to look alike because they evolved similar adaptations

What is punctuated equilibrium?

• The change in allele frequencies of a population due to chance

• The development of new species from pre-existing species

• Long periods of little or no change interrupted by short periods of rapid change

• The idea that evolution occurs slowly and gradually

What is coevolution?

• Process by which two species evolve in response to changes in each other over time

• Process in which single species evolve into diverse species that live in different ways

• The development of new species from pre-existing species

• Large changes that occur over time between different species

What is convergent evolution?

• Process in which unrelated species come to look alike because they evolved similar adaptations

• Process by which two species evolve in response to changes in each other

• Occurs when the rate of speciation is grater than the rate of extinction

• Long periods of little or no change are interrupted by short periods of rapid change

What is adaptive radiation?

• Process by which two species evolve in response to changes in each other

• Process in which unrelated species come to look alike because they evolved similar adaptations

• Process in which a single species evolves into diverse species that live in different ways

• None of the above
