Question

-What concept is illustrated by the figure above?
A) gradualism 
B) hybridization 
C) punctualism 
D) polyploidy

Accepted Answer

Punctualism, also known as punctuated equilibrium, is a concept in evolutionary biology that suggests species remain relatively stable for long periods, punctuated by short, rapid changes. This concept contrasts with gradualism, which proposes slow, steady change over time. The question mentions a figure (not visible here), but based on the options provided and the description, punctualism is the concept that involves rapid changes after periods of stability, fitting the scenario typically illustrated to contrast with gradual evolutionary changes.
