when does life begin ?

"Life" is a characteristic that distinguishes objects that have signaling and self-sustaining processes from those that do not.

This is the biological interpretation. Life begins when you maintain and signal self-sustaining processes. If you define it otherwise, then many things are "alive". Which is weird.

A better question is when do we become "self aware" or "conscious". This occurs in children around 5-6 months of age. This is the method of demarcating between a child, and lets say an animal or a tree.

If we are talking about fetuses. At conception the fetus is not considered alive by the biological definition (it is not self-sustaining, it requires symbiotic growth and attachment to another organism of which disconnection would cause immediate death) and it doesn't fit our "self aware" definition either.

If fetuses are alive at conception then we grant the same idea to animals, trees, viruses, single cells, spermatozoa, and anything that can function but cannot self regulate. [Animals, trees and viruses are actually self regulating, so they are "more" alive then a fetus].

Hope that helps.

If you mean an individual of a species then it is a continuation of life. In mammals, the egg and sperm are both alive as are the male and female that formed them. There is no new life where there was none before.

I understand that many people (and also religious groups) would like to pronounce that at a certain selected point a new individual 'comes into being' where there was no life before. There was life before, and any selected point would be quite contrived and arbitrary.

Reside is evil backwards, ahh hell clones are dwelling tissue inseminated as Kyton stated, it functions the question as a substitute is when human beings are human and no longer simply the cells they're made of, Charles Manson complained that the choose and jury of his trail ate meat and therefore where as guilty of homicide as he was once, however genuine, the jury proved his factor and the choose symbolically murdered him with the death penalty, which he barely escaped from. Ethics is a question established on the herd of conformity, what behavior is suitable to the race is at all times founded on whim. So basing it on my whim, clones are life.

There is no firm beginning to life. It is a slow, spectral development. A burgeoning of self-sustained consciousness, a messy stew of cells coalescing into a steady beat.

Only fools with agendas insist on a fixed beginning.

Im a feminist, so I think life begins the moment the baby is completely OUT of a woman, if the baby is still in the woman, then it is not alive yet and it is actually still part of its mother,.

It began for me when B A T M A N came back to the theater.
