Aristotle believed that organisms could differ from the species-norm with regard only to (a) "accidental" characteristics like size and hair color, and (b) "deficiencies," which They think that natural kinds, including biological taxa, are united by similarity within the species-population, and this is what needs to be explained by homeostatic mechanisms. According to the HPC account, homeostatic mechanisms themselves are similarities that unite a species. Supporters of the HPC theory agree that species and other biological HPC approach is that the mechanisms that cause the homeostatic clustering of similarities need not be intrinsic features of a kind's members. that share a cluster of homeostatic similarities, species are natural kinds.	./cache/work_snx7i34yqrg6hkgs3772knfzru.pdf	./txt/work_snx7i34yqrg6hkgs3772knfzru.txt
