1) When is it a life? Seems like a bad question. It’s always alive. The sperm and egg are alive. The fused product is alive. The blastocyst is alive, etc.
Yes, this is a bad question. Life began 3.5 billion years ago. Life does not begin. Life is a continuum. The DNA passes through organisms over time, where there is viable DNA there is life. A cheek cell has life.
**2) When is it human? When it has 46 chromosomes? Is it based on it’s potential to grow into a baby? Does that mean that embryos in cold storage are just as human?
What about when the stem cell “holy grail” is reached and we learn how to grow any tissue (or even a whole human) from adult stem cells. Are your bone marrow cells morally individual humans?
**
If it is human DNA, then it is human. Humans evolved from non-human DNA. Humans do not just appear, they evolved.

3) Some successful cloining techniques are basically taking a body cell and exchanging the cytoplasm with an egg cell’s cytoplasm. Is killing the cell after the cytoplasmic exchange murder, or abortion, or what?

Murder and abortion are ethical questions. Society decides what defines murder/abortion. Is it OK to kill a terminally ill person in great pain? Capital punishment? etc. This varies from culture to culture, in different times and regions.

4) What makes killing a human embryo/fetal bundle of cells in the shape of a ball, or a fish, or a pig (ontologically speaking) better than killing a bundle in the shape of a baby? Is it the complexity? The lack of resemblance to an adult? Is it the ick factor of dismembering a little body?

Again, it is an ethical decision. It is the awareness of self and depth of psycholocial pain that the life form and its kin feel through death that should determine this.
A new born baby may have a sense of awareness no greater than a kitten, but the family usually would not.
So, a human does not start at some point in time. A life does not start at some point in time. They are both part of a continuum of change, linked to a very special molecule, that formed a long time ago.
Science cannot offer an answer to the ethical question.
Self awareness gradually develops in a being. A ‘human being’ gradually develops/diminishes throughout its entire life. The cut off point for termination of the being at any point in life is a decision based purely on ethics of the society.
I think even sven and december are closest the mark.
