<span>b The growth of teeth in chickens supports the hypothesis of a common ancestor between birds and reptiles. This is a generally accepted hypothesis, and i'd go with this answer.

Carbon is very important because Trees take it (Co2) in in order for oxygen to be produced.
All plants for the most part take in Co2 so that they can produce oxygen,
