My question is this: should I leave the grow light on 24 hours a day, even during daylight hours, or should I turn it off during the day? They do get sunlight during the day, but certainly not as much as if they were on my main living floor (but that won't work logistically, so the basement it is).
Neanderthals (or Neandertals) are our closest extinct human relatives. There is some debate as to whether they were a distinct species of the Homo genus (Homo neanderthalensis) or a subspecies of Homo sapiens.
Neanderthals were shorter than modern man, with longer skulls, jutting brows and chins, and had large torsos with short limbs. They were not adapted for running and hunting in the same way as Cro-Magnon.
