The species concept debate has devolved from an empirical discussion into a philosophical one. But this is fundamentally an empirical question. These data support the notion that species can be both units of evolution and products of evolution.

After going through all this literature, we realized someone just needed to compile and analyze it all.

These discussions should have been settled earlier, but no one bothered to summarize the relevant literature, perhaps because it is so vast.

Our parties and Presidential candidates must find ways to differ without being destructive, to debate without demonizing, to put our national interest ahead of special interests, to take the long view rather than the most politically expedient short-term view, to rise above partisan politics to put America first.

The dividing question in the debate is not do we do something, but whatever we do, do we do it alone?

I don't debate with liars.
