Evolution Exam

Front

What is gradualism in the context of evolution?

Back

Gradualism is the theory that evolution occurs slowly and steadily over a long period of time, with small, incremental changes.

Front

What is punctuated equilibrium?

Back

Punctuated equilibrium is the theory that evolution occurs in rapid bursts of change followed by long periods of stability or stasis.

Front

How does natural selection influence the size of modern scorpions compared to their ancestors?

Back

Natural selection has led to changes in scorpions, resulting in them being much smaller than their extinct ancestors.

Front

What evolutionary pattern did Charles Darwin support?

Back

Charles Darwin supported the pattern of gradualism, believing that evolution occurs through small changes over long periods.

Front

Which species has the fewest amino acid differences compared to humans?

Back

Chimpanzees have the fewest amino acid differences compared to humans.

Front

What is the significance of amino acid differences in evolutionary biology?

Back

Amino acid differences can indicate the degree of genetic similarity and evolutionary relationship between species.

Front

What is the role of beneficial adaptations in evolution?

Back

Beneficial adaptations are traits that enhance an organism's ability to survive and reproduce in its environment, contributing to evolutionary success.

Front

How many species of lizards in the provided graph have beneficial adaptations?

Back

According to the graph, 2 species of lizards have beneficial adaptations.

Front

What is the concept of speciation?

Back

Speciation is the process by which new species arise from existing species, often due to evolutionary changes.

Front

What evidence supports the theory of evolution?

Back

Evidence for evolution includes fossil records, genetic similarities, and observable changes in species over time.
