A rep for Charles Kelley was not immediately available for comment. Truth or rumor, when news that the singer was splitting hit the internet Sunday (October 18), Twitter immediately exploded with pithy commentary.
Best Answer: Blame it on the comet that struck earth. All animals larger then 10kg died of. Just leaving behind small mammals, small reptiles and tiny beaked flying dinosaurs (birds). All the cool giant dinosaurs died out and you just left with tiny birds which evolve to various bird species including the chicken.
Feduccia believes that birds were very widespread by that date, occupying a variety of habitats. He believes most of them died out with the dinosaurs, about 65 million years ago. The ancestors of all today's birds evolved later, he says, between 65 and 53 million years ago, independently of the dinosaurs. This is the big bang theory of birds.
