Perhaps. But how does that make it a life? A swamp or wetland has its own biochemistry. Does that mean that it is alive? There is no single, simple definition of life.
Would you agree that an entity with energetic needs, which needs biological systems to utilize energy, deal with waste products, maintain homeostasis, is a living thing?
I think so. And the embryo fulfills all these conditions, right from the birth? When it is two or four cells, it has all this?
It is living in the sense that it has a definite biochemistry system to deal with the issues of being a living thing...
Again, at what point does its have its own biochemistry? It can’t be from the moment of conception.
The cells in human body can remain alive indefinitely in a Petri dish. - SJP
But the whole body, ie the human being, cannot. - Tonington
Same could be said of say, a one month embryo. Its individual cells can remain alive, but the embryo cannot, outside mother’s body.
So is the embryo alive in the sense that dead body is alive, or in the sense that a human being is alive? We don’t know. - SJP
I know. You don't know. - Tonington - Tonington
That is right, you may, but I don’t know. When life begins is a very complex question, there is no simple answer. Scientists rightly stay away from the subject.
I am quite certain that your denial of modern biology and chemistry, and the complex interplay between the two is driven purely by your politics.
There is no denial here, Tonington. When there is a scientific consensus that life begins at conception, I will believe it. In matters of science, I defer to scientists, in this case biologists (I am a physical scientist, not a biologist).
Right, the DNA is what tells us it was a human. Please stop being so obtuse.
But the dead body also has DNA, the cells in the dead body have DNA. DNA tells us it is human if it is alive. However, DNA by itself does not tell us if it is alive or not.
Anyway, I am off now. We will pick it up tomorrow, if you wish.
