Scientists have grown dinosaur-like snouts on chicken embryos, revealing how the bird beak may have evolved.
Birds are thought to have evolved from dinosaurs, but have very different jaws. Bird-like dinosaurs such as the velociraptor have two bones at the tip of their upper jaws. In birds, those bones are fused to form a beak.
By blocking two proteins that are activated when chicken embryos grow their beaks, U.S. researchers caused their jaws to "revert" to a velociraptor-like snout. The changes were observed in chick embryos that developed until they were close to hatching.
To their surprise, the birds' palates, on the roof of their mouths, also became dinosaur-like.

Refute that!

"No! God poofed dinosaurs and birds into existence separately! The bible says so!"
