Mayr take me home ping.

Liberals are a diffent species.

Some people claim that there are currently more than one species of humans on planet Earth. Any serious research regarding this assertion is of course forbidden due to claims of racism and political correctness. Even if the argument for separate species is debatable it’s hard to argue that several subspecies don’t exist.

[Capt. Tom]

For biologists, like Mayr, species are entities composed of individuals that, in the wild, reproduce among themselves but not with other species.

But palaeontologists use other definitions of species and these have allowed them to classify fossils that cannot be otherwise categorised on the basis of Mayr's biological species concept.

Tom here: The Australian black tip shark (Carcharhinus tilstoni) and the common black tip shark (C. limbatus) have overlapping distributions along the northern and eastern Australian coastline. These shark species have been known to interbreed. -tom

As I sit here watching my daughter’s pug play with my Boston bull, I wonder just how clear our idea of species is? Herto man, Neanderthal, Rodesinsis, and others are found over wide areas going back to the earliest Homo Sapiens some 206 k years ago in China no less. The oldest date for Homo Sapiens I’m aware of for Africa is 160 k to 190 k for White’s Awash discoveries.

There are lots of egos involved in human origins research. There are also complications by folks who don’t believe all “people” are human. Am I a Homo Sapiens Sapiens or some lesser creature. It all depends on who is making the definitions.

Recent dna testing of an alleged yeti finger turned up as ‘human’; what else would one expect? What is human? Homo Sapiens Sapiens only? Isn’t there evidence of Homo blank blank from the recent past? Didn’t Linneus include Homo Sylvestris in his classification system? Carl was onto something.

H. sapiens I don’t know about, but I think p. paniscus deserves its own genus.
