Sorry but its fact that biology determines whether or not you are an individual. If we all had the exact same DNA, we'd be clones, not individuals. We could still have individual personalities (social, philosophical and theological individuality) but biologically, we'd be identical.
We don't know? Here's just one example:
Corpses are protected by law, they retain some rights as individuals even after death.
That depends on the definition of "is".... We've been through this before already and you said you would leave the unprovable, philosophical and theological arguments at the door and focus solely on the scientifically provable aspects of the discussion... Can we do that now?
DNA, without which you would not exist and could not grow. Without your DNA being different from everyone elses, you would not be an individual but a clone. You continally add this layer of spirituality... I think you do it because there is no answer to those unknown question and its comforting for you to think there are no answers to tough questions... you refuse to stay focused on what is known, and knowable, regarding these difficult topics.
I don't call myself an Atheist but that is basically my position. However I don't believe we're "simply" biological entities but its only the biological aspects of our existance that can be scientifically quantified and empirically proven... We cannot quantify, much less prove with any level of certainty, the other aspects of being human, e.g. existence of the soul.
The spiritual, theological and social aspects are all subjective to the individual pondering them and have no definitive answers, its only those with faith who can look at the unprovable and claim that they know for sure.
If I had to guess based on our discussion, I'd say you were Agnostic... You refuse to deal in absolutes and like to stay safely in the gray areas saying that we'll never know because no one can answer the unanswerable questions you insist on adding to the answerable ones.
Safely in the gray areas? We've been discussing a gray area for several pages, now. You're trying to make them black and white, but they're not.
We cannot quantify, much less prove with any level of certainty, the other aspects of being human, e.g. existence of the soul.
Perhaps not, but we can prove with certainty that the human mind exists in an adult human, but not in a days old embryo.

OK, so it is known that our DNA is one thing that makes us a unique individual, that's so. How, though, does it follow that life begins when our DNA is complete? It seems to me that there is a disconnect there.
More on DNA:
Mice carrying a "humanized version" of a gene believed to influence speech and language may not actually talk, but they nonetheless do have a lot to say about our evolutionary past, according to a report in the May 29th issue of the journal Cell, a Cell Press publication.
"In the last decade or so, we've come to realize that the mouse is really similar to humans," said Wolfgang Enard of the Max-Planck Institute for Evolutionary Anthropology. "The genes are essentially the same and they also work similarly." Because of that, scientists have learned a tremendous amount about the biology of human diseases by studying mice.
If it is our DNA that makes us unique human individuals, what are mice that have human DNA spliced into their genes? Are they partly human as well?
