Niglets mature faster than human babies, and become strong and coordinated much earlier. Niglet sheboons reach sexual maturity a full year earlier than humans. They 'seem' equally as social and emotionally intelligent until they hit the preteen years, which is when their intellect stops maturing, while human intellect continues to mature into the early 20's. Sheboon's gestation period is a full week shorter than humans'. Nigger life expectancy adjusting for external factors is also 7-10 years shorter. Niggers put less energy into their offspring, have more niglets, and live shorter lives. They also have more and larger stink glands vs. humans which secrete different chemicals making them stinkier. They have an underdeveloped prefrontal cortex, which explains their childlike behavior, propensity for violence, and impulsivity. Their bones are more dense, which is why niggers can't swim. Purebred niggers have 68 IQ's on average, 2 standard deviations below humans, which is severe mental retardation by human standards. They have nasty, gross hair, smaller brains, disparate skeletal structures, and what could be described as chimp-like behavior. We are different species.
