A couple months ago I lamented that so much of what I learned as a child about dinosaurs was incorrect.
A new theory suggests that smaller, feathered dinosaurs developed wings to help them stay on top of prey about their size when grabbing it with raptor-like claws. Much safer grappling from on top where your prey's teeth and claws cannot reach!
The theory itself is too new to deserve much comment, but the article is a great example of how dinosaur knowledge has changed since my childhood, when the Archaeopteryx was the only feathered dinosaur talked about.
