When Does Human Life Begin? Please take part in our poll

Behind the stem cell “war” that has been going on for years is a deceptively simple question: when does the life of a human being begin?

As someone who works with human embryonic stem cells and iPS cells, I’ve given this a lot of thought. But first, before I post on that, I want to know what you think. So I’ve created a poll above. Please participate and in the comments elaborate on your opinion.

  1. I believe that life begins at implantation.

    I once heard that 3 out of 4 fertilized eggs fail to implant. I wonder if there are any sources out there to confirm that.
