The cerebral rubicon is a disused concept in paleoanthropology that proposed a minimum cranial capacity as the decisive threshold for assigning hominins to the genus Homo. The idea was introduced in the early 20th century by Scottish anthropologist Sir Arthur Keith, who argued that a brain volume of at least 750 cubic centimeters marked the point separating early humans from non-human primates and earlier australopithecine ancestors.
