Well, every species nutrition tends to be quite unique, but it is still quite open is it actually good for us to drink milk. Anyways, we're not the only ones to enslave other species, or other races. Perfect example: ants! And if we think machines are something that has at least one moving part, some animals in addition to humans are already very close (in evolutionary meaning, so it's going to take a lot of time from our perspective) to actually use very primitive machines. Most of animals tend to use in some form materials what they have around.
