New study shakes the roots of the dinosaur family tree
More than a century of theory about the evolutionary history of dinosaurs has been turned on its head following the publication of new research. The work suggests that the family groupings need to be rearranged, redefined and renamed and also that dinosaurs may have originated in the northern hemisphere rather than the southern, as current thinking goes.

Yup, and to a rocket surgeon like me. I have always been a little leery about the way we pompously group and classify things like we have this all powerful knowledge, only to find out we were wrong years or decades later. This is why I approach everything that is supposedly proven science with a big dollop of skepticism. Heck, we missed this one by so much that we can't even classify a certain dinosaur as a dinosaur.
