the life cycle also encompasses a single generation: the individual animal begins with the fusion of male and female sex cells (gametes);
Life cycle entails the course of development of an organism, i.e. from the time of inception to growth to finally maturity when an organism can viably produce another of its kind.
The human life cycle begins at fertilization, when an egg cell inside a woman and a sperm cell from a man fuse to form a one-celled zygote .
Fertilisation, also spelt fertilization (also known as conception, fecundation and syngamy), is fusion of gametes to form a new organism of the same species.
As I stated, and agreed with you, technically "life" does begin with fertilisation, but that has nothing to do with the definition of a human being... there is a decided difference between basic life and a fully developed organism.

hey hey hey... easy with the castration talk... some of us un-needed males are on your side... so step away from the hedge clippers please...
As far as I'm concerned this issue never get's past "it's their body". I refuse to even try to tell them what to do with it.

Not to mention, we are in mutual need of one another, otherwise, a large percentage of pregnancies would not even have to happen right?

This source says brain function begins at 40-43 days.
I also found this.
"The nervous system develops from the neural plate which appears during the third week of development. About six weeks after conception, the child's brain is sending out impulses which control body functions, and the nervous system is controlling the child's movements. At seven weeks the unborn child responds to touch. At twelve weeks, the brain is fully formed, and of couse it continues to grow as the child grows. It is unmistakeably evident that the tiny growing fetus responds to its environment and knows when it is injured. If injured, the small child exhibits an awareness of intense pain."
Functional maturity of the cerebral cortex is suggested by fetal and neonatal electroencephalographic patterns...First, intermittent electroencephalograpic bursts in both cerebral hemispheres are first seen at 20 weeks gestation; they become sustained at 22 weeks and bilaterally synchronous at 26 to 27 weeks.
Abstract
This paper suggests that medically the term a 'human being' should be defined by the presence of an active human brain. The brain is the only unique and irreplaceable organ in the human body, as the orchestrator of all organ systems and the seat of personality. Thus, the presence or absence of brain life truly defines the presence or absence of human life in the medical sense. When viewed in this way, human life may be seen as a continuous spectrum between the onset of brain life in utero (eight weeks gestation), until the occurrence of brain death. At any point human tissue or organ systems may be present, but without the presence of a functional human brain, these do not constitute a 'human being', at least in a medical sense. The implications of this theory for various ethical concerns such as in vitro fertilisation and abortion are discussed. This theory is the most consistent possible for the definition of a human being with no contradictions inherent. However, having a good theory of definition of a 'human being' does not necessarily solve the ethical problems discussed herein.
Intro
In recent years, there has been much discussion of the need to refine and update the criteria for determining that a human being has died. In light of medicines' increasing ability to maintain certain signs of life artificially and to make good use of organs from newly dead.

It is disturbing that you see the same people over and over in abortion threads so passionately defending the murdering of babies.
I have shown in other threads that a "fetus" is biologically considered a living human being...just like any other life in biology...a new "life" begins at conception. This is basic fact you can find in any biology book.
But what I have learned is that some demented people are so hell bent on supporting the killing of babies...they will deny scientific facts for this argument to switch over to "philosophy"...and then outright reject and ridicule a religous opposing view...even though that is also "philosophy". My position is neither...it is backed by science and biology....abortion is ending a human life...thus it is MURDER.
But some people seem to just have a passion for killing babies...I've come to the conclusion that you can't speak logically to people who are so demented that they think killing babies is justified becuase their government has told them it is "legal".edit on 10-11-2011 by OutKast Searcher because: (no reason given)

Stop spreading blatant lies. If you supported scientific fact then you should know legally aborted fetuses did not have the neurological connections necessary to feel
Sorry...but biology is not a lie.
And your "argument" suggest that if I kill you and you don't feel it...then it isn't a crime
Murder has nothing to do with "feeling pain"...it has to do with ending the life of another human being.
You can call them "lies" all you want...but these are facts...the biological definition of the beginning of "LIFE" is conception. Abortion is ending that "LIFE"...hence it is MURDER.
I'm sorry if that makes you feel uncomfortable...on second thought...I'm not....it should make you feel uncomfortable and angry that millions of babies are MURDERED by their own (heartless) mothers.

Yes...and biology says that a "fully developed organisim" is one that can reproduce itself (Maturity).
So...shall we allow the murder of kids up until they can reproduce???
The fact is that you are picking a completely arbitrary point in the development life cycle of the human being to decide that this is "LIFE". There is nothing you can say to prove that the point you select is more valide than someone elses. One person says when the heart beats, someone else says when there is brain function, someone else says when there is a nervous system, someone else says when they are "sentient" (that has it's own definition problems), someone else says it's when they are outside the womb.
Who is right?
My answer...none of you...because you are all just picking a random point in the development to say "This is when you are actually human".
I pick the only logical point in the life cycle to say you are human....at the very start...conception. It's consistent with scientific knowledge...I don't have to rely on a philosophical argument like you do to justify my starting point in life.
I am not making an arbitrary point in the development, the scientific community has, as a consensus come to a definition to define what a human being is based on gathered scientific data pertaining to embryonic development.
Murder is defined an unlawful killing of a human person. Not all killing of human life is murder. When human life is not a person, killing it is not murder.
It refers to a discrete life form that has properties of mind (sentience), which are deemed to constitute a more complex state than simple organisms (i.e. that have only "life functions").[
A fetus is an undeveloped being incapable of thought and feeling. They do not know they are a living thing, they do not feel that they are a living thing. How many living creatures have you killed, how many buys and germs have you killed? We're all murderers why is that so hard for you to understand?
The only discomfort I feel stems from your blatant ignorance. I am not discomforted by the fact that ALL OF US that are living right now could be dead tomorrow. We could all be dead in five seconds. But YOU discomfort me with your idiocy.
Wrong, you rely on philosophy just like anyone else. You cannot justify why we must value human life without philosophy. Why is your opinion that humans must be protected from conception more valid or more objective (less philosophical) than any other opinion?
This argument is about valuing human life...as a society we have already decided on that.

Hi..
i encountered this short story and wanted to share with you :
A worried woman went to her gynecologist and said:
'Doctor, I have a serious problem and desperately need your help! My baby is not even 1 year old and I'm pregnant again. I don't want kids so close together.'
So the doctor said: 'Ok and what do you want me to do?'
She said: 'I want you to end my pregnancy, and I'm counting on your help with this.'
The doctor thought for a little, and after some silence he said to the lady: 'I think I have a better solution for your problem. It's less dangerous for you too.'
She smiled, thinking that the doctor was going to accept her request.
Then he continued: 'You see, in order for you not to have to take care of 2 babies at the same time, let's kill the one in your arms. This way, you could rest some before the other one is born. If we're going to kill one of them, it doesn't matter which one it is. There would be no risk for your body if you chose the one in your arms.'
The lady was horrified and said: 'No doctor! How terrible! It's a crime to kill a child!'
'I agree', the doctor replied. 'But you seemed to be OK with it, so I thought maybe that was the best solution.'
The doctor smiled, realizing that he had made his point.
He convinced the mom that there is no difference in killing a child that's already been born and one that's still in the womb. The crime is the same!
