Of course. We don't become something different because of our geographical location (inside/outside). We are just what we are in a different location.
Yes it is if fertilization is complete. Do you believe it is fine to create human beings for the purpose of medical experimentation? Those stem cell lines that are presently being used are in effect families of human beings who will never have any chance at life beyond being the subject of medical research.
At the point that is analogous to fertilization. At the point that it has a complete set of 46 chromosomes.
No.
No. It has been alive for some small time before it organizes enough to begin communication.
Again, we aren't a different thing because we are in a different geographical location. If you began with a liver cell for instance and were able to direct the growth of a liver from that cell without having to create an embryo first, then you would not be experimenting on human beings, you would be experimenting with human tissue which is fine by me.
I never suggested that they were human because they could communicate. They are human beings by virtue of what they are. I merely pointed out that they communicate with their mother to explain to coyote that we can detect that a woman has been pregnant even if the child never implants into the uterus.
Then the fault lies with you and your inability to grasp the biology of developmental biology. No offense but that is explanation enough. I simply can't wrap my mind around certain concepts in quantum physics (effect being a precursor to cause for example). The fact that I can't grasp the concept however has absolutely nothing to do with the reality.
