1 is wrong. Please try again.

"Human" means

This is what we have in mind in the biology lab when we distinguish between a "mouse fetus" and a "human fetus."

But the term is also used in other senses.

4 is correct!

"Human" means

    { 1 } - "born or unborn member of the species Homo sapiens."
    { 2 } - "born member of the species Homo sapiens."
    { 3 } - "animal who reasons."
    { 4 } - The term is ambiguous and can mean any of these.

A fetus is "human" in sense 1, but not in senses 2 or 3. So whether a fetus is "human" depends on which sense we use.

The real issue is this: Which sense should we use in the premise that goes "Killing innocent human life is seriously wrong"? We get different principles depending on which sense of "human" we pick. Which of the principles should we accept?
