What makes a human? What makes a person?
A human is a specific organism within the species of homosapien. A person, on the contrary, is an individual.
A human can be described as anything seemingly being that with our body.

If you were to find a dead body, you would say: "Somebody killed this person". You may also say something like, "This was a person".
You wouldn't however, say "This was a human". Are they not a person anymore?
In my opinion, a person constitutes something of the conciseness rather than the entirety of a body. A human, being that of the body itself. Humans change. A person doesn't.
A person can change their personality, physical appearance, etc., but they cannot change their species. A person is an individual inside the human species.
But would that not mean that a rabbit is a person inside their own species? Or are they less than us? This raises the question; what is different between a person in the human species, and a person in the species, of, say, a cat.
Well. Quite a lot of things. Assume we're speaking about an individual cat
