The difference between phyletic gradualism and punctuated equilibrium is that

A) phyletic gradualism is specific to eukaryotes and punctuated equilibrium is specific to prokaryotes.
B) punctuated equilibrium states that speciation can occur in a relatively short period of time, while phyletic gradualism states that speciation occurs gradually over vast periods of time.
C) phyletic gradualism states that speciation can occur over a relatively short time period, while punctuated equilibrium states that speciation requires vast periods of time.
D) the fossil record only supports phyletic gradualism.
E) the fossil record only supports punctuated equilibrium.

Phyletic Gradualism

Phyletic gradualism is an evolutionary model proposing that species evolve through gradual changes of traits over long periods of time.

Punctuated Equilibrium

A theory in evolutionary biology that suggests species evolve rapidly during short periods of time followed by long periods of stasis.

Speciation

Speciation is the evolutionary process by which populations evolve to become distinct species, typically by being geographically isolated from one another and experiencing different environmental pressures.

  • Differentiate various theories of evolution, including punctuated equilibrium and phyletic gradualism.

Final Answer :
B
Explanation :
Phyletic gradualism and punctuated equilibrium are both theories about the pace of evolution. Phyletic gradualism posits that evolution occurs slowly and steadily over long periods of time, while punctuated equilibrium suggests that evolutionary change happens quickly in short bursts, followed by long periods of stasis. Therefore, the correct answer is B, as it accurately reflects the difference between the two theories.
