For example, there are birds which were considered to be seperate species which are in fact regional variants. Different, yet the same. They can interbreed.
Would this eventually lead to a new species? Under the right conditions probably.
You put your credentials in your sig. You should know that the influenva virus has variants, but it is still the influenza virus. My friends at Cold Spring Harbor, and the NIH haven't called me and said that there is a new "species" of virus.
You can beat up on the creationists if you like, but the whole OP's tongue in cheek slam isn't really a basis for valid criticism.
Nowhere did Meuge state anything about evolution entailing speciation, only that evolution is a change in gene frequencies in a population from one population to the next.
You might want to check with 'your friends at CSH', because they've been well aware of species concepts issues for at least the last forty years. There is no such thing as a species, there are only pragmatic, yet artificially imposed descriptions of groups of organisms with varying levels of basis in reality contingent upon the questions being asked by biologists working in different specialties (about two dozen last time I checked). For example, Meuge's definition of a species (as an immunologist dealing with microbes) is probably much different than my own (as a paleoanthropologist). Hence, he cautions against paying attention to 'micro- & macroevolutionary' arguments. They're the same thing... Evolution, either by means of natural selection, or genetic drift, or simply non-adaptive (neutral) mutation. Don't dis the OP when you yourself don't really know whatchoo talkin' 'bout.

If evolution is a true fact, then what do you care what the ignorant rubes think?
Aside from a deeply-held belief that knowledge is preferable to ignorance, the more pressing concern is that ignorant rubes can incubate & transmit disease and I dislike being sick.
Instead of outright refusing to issue flu vaccines to those who deny evolution (which while amusing to those frustrated by Medieval America, isn't exactly ethical), I propose we instead offer vaccines which hopefully work against constantly evolving virii, or cranial trepanation to release the demons responsible for debilitating illness.
Which would you choose, glenn1?
