Neanderthals had bigger brains than modern humans

@ChipmunkErnie that used to be the definition of species. Interbreed and have fertile offspring. Now it goes by having distinct genetic pools, even with the occasional interbreeding.

@Cyclist Scientists just can't leave well-enough alone. LOL But I did find this, so it seems to depend on who's using the term... "A species (pl.species) is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. It can be defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined."
