Evolutionary scientists are trying to find evidence that dinosaurs were warm-blooded creatures in order to place them closer to birds on their evolutionary diagrams. According to Dr. Tom Holtz, “Birds are dinosaurs! And because birds live today, dinosaurs never did become extinct.” Does science back this story? Most of the evidence for dinosaurs possessing a bird-like metabolism is misrepresented.To read the rest, click on "Dinosaurs Designed Cold-Blooded".
If dinosaurs were birds, they should’ve been endothermic (warm-blooded) like birds today. Endothermic simply means that an animal generates its own internal body heat using its metabolism, independent of its surroundings. Ectothermic (cold-blooded) means that an animal needs an external source of heat, like sunlight, to warm its body, like snakes and lizards do.
Unfortunately, determining whether or not an extinct animal is endothermic or ectothermic is difficult and requires a study of soft-tissue anatomy. Because only small amounts of soft tissue are preserved in dinosaur fossils, we still don’t know for sure if dinosaurs were warm or cold-blooded.
Many evolutionists insist that dinosaurs evolved into birds. They have to use bad data to change cold-blooded dinosaurs into warm-blooded, because birds are warm-blooded. This is science?
