If your instinct tells you that that it's all Politics with a capital P behind much of biological science, then your instincts are correct. Just as Phil Jones and Michael Mann have corrupted "climate science" (whatever the heck that means) by their own greed, vanity, and ideology, so too do biological scientists seek self-aggrandizement over humble scientific inquiry.
Just remember the word "species" is quite malleable, especially by those on the Left. My personal opinion is that the word is being corrupted for political gain. After all, if we can split the western flycatcher into 2 suboscine species that are virtually identical -- the Cordilleran and the pacific-slope -- then in a roundabout way, we've "proven" the exigency and expedition of evolution in action, haven't we?
They took the word "gay," and corrupted it. They're trying to take the word "marriage" and corrupt it. Tomorrow, it will be the word "species."
Yes, appalling.
And just what is the political object behind all this?
