The fact that Encephalization Quotients (EQs) of organisms have generally increased with time provides evidence for
A) cross-breeding between organisms
B) artificial selection
C) genetic mutations
D) convergent evolution toward increasing intelligence

Question

Quizplus · Accepted Answer

Encephalization Quotients (EQs) refer to the relative size of an animal's brain to their body size. The fact that EQs have generally increased with time suggests that there has been a trend towards increasing intelligence in some animal lineages, which is an example of convergent evolution. This increase in intelligence is not likely due to cross-breeding between organisms, artificial selection or genetic mutations alone, but rather a result of evolutionary processes favoring more intelligent individuals within a particular species over time.
