Actually, it was done by Linné in 1766: Homo sapiens with two species, homo diurnus (day man) and homo nocturnus (night man).
Oh wait . . . i might have misundestood. Are you saying you can't get laid because you can't sing?
And unfortunately, there is no mutant human species whose females dig obese males.
So I had to look it up .... the narrator goes to the Linnaean Society ...
Regarding your reference to Neanderthal DNA, you might find the following of interest.
Quote:Many people alive today possess some Neanderthal ancestry, according to a landmark scientific study.
The finding has surprised many experts, as previous genetic evidence suggested the Neanderthals made little or no contribution to our inheritance.
The result comes from analysis of the Neanderthal genome - the "instruction manual" describing how these ancient humans were put together.
Between 1% and 4% of the Eurasian human genome seems to come from Neanderthals.
But the study confirms living humans overwhelmingly trace their ancestry to a small population of Africans who later spread out across the world.
You lost yourself when you argued that Homosapiens mated with Neanderthals creating Homosapiens.
Can humans be divided ito subspecies?
In 1933, three strange dolphins beached off the Irish coast; they appeared to be hybrids between Risso's and bottlenose dolphins. This mating was later repeated in captivity, producing a hybrid calf. In captivity, a bottlenose and a rough-toothed dolphin produced hybrid offspring. A common-bottlenose hybrid lives at SeaWorld California. Other dolphin hybrids live in captivity around the world or have been reported in the wild, such as a bottlenose-Atlantic spotted hybrid. The best known hybrid is the wolphin, a false killer whale-bottlenose dolphin hybrid. The wolphin is a fertile hybrid. Two wolphins currently live at the Sea Life Park in Hawaii; the first was born in 1985 from a male false killer whale and a female bottlenose. Wolphins have also been observed in the wild
So why are humans exempt from this system?
How does one account for the current theory that there was mixing between Neanderthal and Homosapiens?
