Has 'one species' idea been put to bed?

Quote:Hobbits on Flores, Denisovans in Siberia, Neanderthals across Eurasia and our very own ancestors.
Given this array of human diversity in the Late Pleistocene, we might well be forgiven for thinking that Ernst Mayr's contention that "in spite of much geographical variation, never more than one species of man existed on Earth at any one time" had finally been put to bed.

Oh you know min, there are always adherance to outdated ideas.
This is the intertubes, after all.
If today you can take a thing like evolution and make it a crime to teach in the public schools, tomorrow you can make it a crime to teach it in the private schools and next year you can make it a crime to teach it to the hustings or in the church. At the next session you may ban books and the newspapers...
Ignorance and fanaticism are ever busy and need feeding. Always feeding and gloating for more. Today it is the public school teachers; tomorrow the private. The next day the preachers and the lecturers, the magazines, the books, the newspapers. After a while, Your Honor, it is the setting of man against man and creed against creed until with flying banners and beating drums we are marching backward to the glorious ages of the sixteenth centry when bigots lighted fagots to burn the men who dared to bring any intelligence and enlightenment and culture to the human mind. ~Clarence Darrow, at the Scopes Monkey Trial, 1925
Politics is supposed to be the second-oldest profession. I have come to realize that it bears a very close resemblance to the first. ~Ronald Reagan

So you admit those other hominid were separate species incapable forming genuine breeding populations with homo sapiens?

Interbreeding does muddy the waters a bit. Us white folks have a significant portion of our DNA is Neaderthall, after all. There's no telling how much more mixing interbred DNA has made it this far.
It just goes to show that we'll screw around with it if the parts fit well enough.

Indeed, it is possible for different, but some closely related sexual species to interbreed in a limited way and produce fertile offspring, thus carry genes from one species to another.
The issue of whether two similar sexual population belongs to the same species thus can not in all cases be ascertained with a single acid test of fertility in offspring.

Didn’t Aleia post something along these lines recently?
Looks around a little….
Yes she did. http://atheistforums.org/thread-10308.html

Could any/all of the diverse groups interbreed?(as apparently did homo neanderthalis and homo sapiens sapiens) If so,they were the same species,if we don't know,we can't make any assertions.

One is the name, always in search of fame. 
All is vanity! Species is traditionally delineated by the ability to breed. One is the state of now, one is common decent; between the two, the naming of shit will get sorted... eventually.

Apparently the Denisovans could interbreed as well.
