GSH Patterns of Evolution

Front

What is gradualism in evolution?

Back

Gradualism is the hypothesis that evolution of a species occurs gradually over time as a slow and constant process.

Front

What is punctuated equilibrium?

Back

Punctuated equilibrium is the hypothesis that evolution of a species occurs in periods of rapid change separated by periods of little or no change.

Front

What is adaptive radiation?

Back

Adaptive radiation is the evolution of an ancestral species into an array of species that occupy different niches.

Front

What is convergent evolution?

Back

Convergent evolution occurs when organisms share physical similarities because they live in similar environments, despite not having a common ancestor.

Front

What is the best definition of evolution?

Back

Evolution is defined as the change of species over time.

Front

What is microevolution?

Back

Microevolution refers to small-scale evolutionary changes within a species, often due to environmental pressures.

Front

What is speciation?

Back

Speciation is the process by which one species evolves into two or more distinct species.

Front

What are homologous structures?

Back

Homologous structures are anatomical features in different species that share a common ancestry, even if their functions differ.

Front

What is coevolution?

Back

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

Front

What is the significance of genetic variation in evolution?

Back

Genetic variation is crucial for evolution as it provides the raw material for natural selection to act upon.
