Study: Dinosaurs "Shrank" Regularly To Become Birds

An anonymous reader writes A new study suggests that large dinosaurs shrunk to small birds to survive over a period of around 50 million years. Aside from a few large species, most modern birds are predominantly tiny and look nothing at all like their prehistoric meat-eating ancestors. The evolutionary process that governed this transformation has not been well understood, but now researchers from the University of Adelaide in Australia have put together a detailed family tree mapping the evolution of therapod dinosaurs to the agile flying birds we see today. Their results indicated that meat-eating dinosaurs underwent several distinct periods of miniaturization over the last 50 million years which took them down from an average weight of 163kg to just 0.8kg before finally becoming modern birds.

  1. Pro-Evolutionists have devolved by mtthwbrnd · · Score: -1, Troll

    Reading through the comments and following the debate, it is clear that evolution may be an incorrect theory - but it is absolutely certain that pro-evolutionists, those who believe in the Theory Of Evolution, have definitely devolved into a state where they can no longer be conversed with in a sensible way by any member of the human species.
