If you know a fact about humans, then mammals are not important. Humans like stories. Doesn’t matter if mammals in general don’t.
If you don’t know a fact about humans, but somehow you know the fact about mammals, you can use it as evidence (although not as a proof). For example, in a culture with a strong religious taboo against human autopsy they could dissect various mammals, and make probabilistic statements about human anatomy.
Today, a more typical situation is two groups of people, each declaring that they know for a fact that humans are / are not X. In such situation, if you have no way to verify the fact directly, I guess you could use the information about mammals to make a probabilistic estimate about which group is correct.
Also, from a perspective of a scientist, if all mammals are X, then the fact that humans are also X is… not completely guaranteed, but not really surprising. On the other hand, if all other mammals are X but humans don’t… that is definitely possible, but it makes me really curious why. What is the difference, and what was the possible reason evolution made it so?
