Yes, it does.
Frequently people will say nothing major changes at the time of birth. They ask what great change takes place. Well, the proverbial slap on the ass to get the breathing started results in a redirection of blood flow. A valve closes at the heart directing the blood flow to the lungs. Veins previously carrying blood to certain organs shut down and atrophy creating "bungee cords" that help hold the organs in place. The "being" goes from a liquid environment to a gaseous one.
I don't know what "major" means to some people but I've suggested they take a fish out of water and watch what happens. And then tie off a vein stopping blood flow to a part of their body and observe the result. Maybe then they'll understand the meaning of "major" change.
wow...so its your contention that a valve closes and presto chango, a human is created ?
Or is it a valve closes and presto chango , what was dead is now alive.....?
Thats a hell of a breakthrough in the science of biology....
Or is it a valve closes but because the newborn cannot reproduce, its not an organism.....?
and the fish story...double wow....take the fish out of water as what ....it changes into a cow ?.....
cut him into little pieces and he becomes sushi...??
You know food intake changes too, and the asshole begins to work, and the kid gets vocal.....amazing stuff....

This is not about morality, religion, or 'cheapening' a human being.....those are not biologic issues....
A fertilized egg, if left to grow and develop in a healthy environment will grow, be born, age, and die all by itself as nature designed.......there is no end product unless a process is started.
There is not a point at which a switch is thrown, or a spark ignites, or angels begin to sing, to denote a human is created......we decide that in an arbitrary manner for our own purpose....
It is what it is from start to finish, beginning to end, ....no matter what you name it, and no matter how many die during their stages of growth and development....time is irrelevant to the biology......an event starts the process of life until it dies for whatever reason....
It doesn't matter whether you pick out 1 second after fertilization, 1 week, 1 month, 1 year, at birth, at 5 years of age, 20 years of age , or 50 years of age.....they are all arbitrary moments established for our own gratification and purpose and not scientific events.....they certainly are stages of growth.....
The process is biological, it begins, ages, and dies......whether the life lasts 1 sec.. 1 day, 5 days or 500 years......
If it were not for the fact that killing a human is the underlying issue that some refuse to acknowledge, their would be no issue.....I don't debate abortion, I can't control how many die or at what stage of life you kill.....what I refuse to do is deny what is done....ending a human life....its legal, at and before a certain age, I have no power to change that and wouldn't if I did have the power....
