Birds from Dinosaurs? Dinosaurs from Birds?

My thanks to kayshapero for the link to this article which upends the last 20 years of conventional wisdom on dinosaur evolution. No, it is not absolutely certain that dinosaurs evolved into birds.

This part of my problem with a number of small scientific fields, like paleontology. They ossify. Yes, we'll appreciate the irony of that. But seriously, when tenure decisions get made by a few people and the same people with the same prejudices also run the peer review journals, it becomes increasingly hard to challenge conventional wisdom. Worse, the temptation to overgeneralize from a handful of samples becomes overwhelming, creating further lock in for the conventional wisdom.
