Question

Quizplus · Accepted Answer

Most basic biological functions, such as respiration, circulation, and digestion, are indeed quite similar across mammals due to their shared evolutionary ancestry. The greatest differences between species, such as laboratory mice and humans, are observed in complex brain functions that govern thoughts, emotions, and personality, which are significantly influenced by the size and structure of the brain, as well as its neural circuitry.
