More accurately: Mathematica has built in and/or automatic access to object data like animals, geographic info, and statistical figures of various things. You can then use these objects in other functions to answer questions like "How similar() is this to a ${goat}" (actual syntax very different) without having to manually code the glue for similar to understand things like animal objects yourself. That the symbolic nature of the program carries past the pure mathematics is one of the most useful things about it.
