Me fast , you (: scientists find evidence that the genes involved in tooth development exist in chickens, even though chickens do not normally develop teeth. the formation of teeth in chickens can be controlled by introducing a virus into chicken embryos that "turned on" their tooth-developing gene. they find that the beaks of the virus-modified chicken embryos contain cone-shaped teeth similar to embryonic crocodile teeth. which of the following best describes the conclusion that can be drawn from this experiment? a as bird evolution continues, birds like chickens will develop teeth like dinosaurs and reptiles. b the growth of teeth in chickens supports the hypothesis of a common ancestor between birds and reptiles. c the chickens with teeth are more closely related to crocodiles than they are to regular toothless chickens. d with enough genetic engineering, chicken embryos can develop into reptiles like crocodiles.
