Quizplus · Accepted Answer

Terry Deacon's research has shown that brain size in early hominin species was the result of brains scaled to different body sizes in hominin species, rather than a linear progression favoring greater intelligence or sexual dimorphism. Brain size increased over time until the appearance of modern humans, with some species exhibiting decreases in brain size during certain periods.
