animals have more rights than any other kingdom of living organisms.

chordates more rights than any other phylum of animal.

mammals have more rights than any other class of chordates.

primates have more rights than any other order of mammals.

hominidae have more rights than any other family of primates.

homo sapiens have more rights than any other species of hominidae.

that's where science draws the lines between organisms, and where rights would fall if solely based on how humanlike an organism is. bees are animals, but they are invertabrates. amoebae are not animals, they are members of the protist kingdom. the further you get from my species, the less value I assign to your existence.

but in my opinion, that's a fairly sociopathic and amoral system for establishing the worth of a lifeform.
