It is hypothesized that reptiles were the immediate evolutionary ancestors of birds.
The larynx of birds is well developed and usable for vocalization, while the larynx of reptiles is simple and not used as a vocal organ.
a. the observation supports the hypothesis
b. the observation opposes the hypothesis
There was also a choice c, which was the observation has no bearing on the hypothesis, but it was not the answer, so I just crossed it out.
Thanks
