If there's one thing evolutionary scientists are "good" at, it's dreaming up theories. Evolutionary theories are a dime a dozen, and a great deal of them can't be tested, which means they don't even qualify as science. Theories that can't be tested are just worthless stories, which suits evolutionary science just fine, because it's a bs-artist's paradise.
Take Stephen Jay Gould, for example: His books were lapped up by the evo-masses, but his ideas didn't advance science one bit. His famous theory - Punctuated Equilbrium - surprise, surprise - can't be tested. Gould was your typical evolutionary "scientist" ... a purveyor of worthless pseudo-scientific stories.
Evolutionary science is the most overrated, useless branch of science in history ... but that doesn't matter, because it's raison d'être is not to advance science, but to advance atheism.
