...which reminds me of science in the medieval era where because Aristotle said something, it was assumed to be true (e.g. women have fewer teeth than men).

Although the Problemata (which contains speculations about the teeth of humans and other animals) was indeed part of the Corpus Aristotelicum, it is very doubtful that Aristotle actually wrote it. In fact, many copies of it list the author as Pseudo-Aristotle.
