Scientists allegedly found remains from a previously unknown branch of the human family in a dark South African cave. In the daylight of Central New England I regularly glimpse offshoot homo sapiens while walking through the city.
The South African scientists call their find homo naledi. I call mine schlomo sapiens.
These occasionally sub-linguistic, often morbidly obese schlomo sapiens — schlomo: Urban Dictionary for lazy person and not Hebrew dictionary for Solomon — represent about as long an evolutionary step from homo sapiens as homo sapiens do from homo naledi. The direction of that step remains up for science to determine.
