Hmm.. I must be misreading something between the two of you then.
Although he did refer to Denisovans, Neanderthals, and Modern Humans as the same generic species.. there was room enough to leave open the door that
they were different sub-species. I don't know if I agree that the Denisovans were close enough to be the same or not, but I'm not an expert in that
What I have looked for, however, is the fact that Homo Sapien Sapien and Homo Sapien Neanderthalis could potentially be the same species, albeit
different subspecies as theorized. Also.. Denisovans definitely had the potential to interbreed not only with neanderthal, but also with modern
humans... therefore, a stronger argument that they may indeed be a subspecies could be made. Again, I'm not a geneticist to tell anyone what to
'classify' something as. All I did was look around for research and found that the three branches of humanity could and did interbreed. In generic
terms, that would mean they're the same species if they're creating - for the most part - viable offspring.
We three groups were all enough alike that some of our ancestors could interbreed and produce fertile offspring. But the differences in the
genomes of Denisovans, Neanderthals, and modern humans are also revealing the genetic traits that set us apart from them—the traits that made us
In biology, a species is one of the basic units of biological classification and a taxonomic rank. A species is often defined as a group of
organisms capable of interbreeding and producing fertile offspring. While in many cases this definition is adequate, the difficulty of defining
species is known as the species problem
But as far as you, Harte, having a definition of species in mind, apparently even the scientific community can't fully agree on a single definition
to the word that will encompass all of the bio-diversity neatly into a nice little DNA package. There are too many factors to consider, including
sub-species.. and apparently in plants they break it down further than that on occassion.
Very interesting thread here.
