Similarities in the vertebrae, pelvis, hind limb, and pectoral arch show that birds may very likely have descended from dinosaurs. Many fossils have been discovered with a "wishbone" and evidence of feathers, showing a link between dinosaurs and birds (even though these dinosaurs most likely could not fly). The best example of a bird-dinosaur hybrid was found in China, incredibly preserved with it's last meal still in it's stomach, and feathers still intact!

How might this theory potentially change a lot of the perceptions of dinosaurs and/or birds?
