This quote by Robert T. Bakker suggests that birds progressed from a little raptor-like theropod. This implies that birds are come down from a group of two-legged, meat-eating dinosaurs. This is supported by the fossil record, which shows that birds developed from theropods throughout the Jurassic duration. Theropods were a diverse group of dinosaurs that consisted of the famous Tyrannosaurus rex. They were defined by their bipedal position, sharp claws, and large heads.
The idea that birds developed from theropods was first proposed by Thomas Henry Huxley in the late 1800s. Since then, researchers have been able to reveal more evidence to support this hypothesis. For example, the fossil record shows that birds have lots of features in common with theropods, such as plumes, hollow bones, and a wishbone. Additionally, hereditary studies have exposed that birds and theropods share much of the same genes.
In general, this quote by Robert T. Bakker recommends that birds evolved from a small raptor-like theropod. This hypothesis is supported by the fossil record and hereditary research studies, which have exposed lots of similarities in between birds and theropods.
"I think I was first awakened to musical exploration by Dizzy Gillespie and Bird. It was through their work that I began to learn about musical structures and the more theoretical aspects of music"
"There are joys which long to be ours. God sends ten thousands truths, which come about us like birds seeking inlet; but we are shut up to them, and so they bring us nothing, but sit and sing awhile upon the roof, and then fly away"
"The white men in the East are like birds. They are hatching out their eggs every year, and there is not room enough in the East, and they must go elsewhere; and they come out West, as you have seen them coming for the last few years"
