Quote by: carriew just incase some of you aren't following the is a fertilized ovum a living member of its species thread ill repost it.
"The development of a human being begins with fertilization, a process by which two highly specialized cells, the spermatozoon from the male and the oocyte from the female, unite to give rise to a new organism, the zygote."
[Langman, Jan. Medical Embryology. 3rd edition. Baltimore: Williams and Wilkins, 1975, p. 3] |
This does not support your claim that a fertilized ovum is a human being.
This says pretty much the same thing as the quote above. Again, this is not a question of whether human life is present. The issue is and has always been is a single cell a human being.
From that site
Quote:
A scientific textbook called “Basics of Biology” gives five characteristics of living things; these five criteria are found in all modern elementary scientific textbooks:
1. Living things are highly organized.
2. All living things have an ability to acquire materials and energy.
3. All living things have an ability to respond to their environment.
4. All living things have an ability to reproduce.
5. All living things have an ability to adapt.

1) A human skin cell is also highly organized.
2) A human skin cell has the ability to acquire materials and energy
3) A human skin cell has the ability to adapt. They change color depending on the amount of sunlight they are exposed to. They toughen up depending how often they come into contact with rough surfaces.
4) A human skin cell has the abity to reproduce.
5) This is just a restatement of 3) I guess the author thought that four bullets were not enough and they had to copy a previous bullet so they would have at least five.
In any case a human skin cell fits these criteria, but it is still not a human being.
For as many scientists that you can find that think a single cell is a human being there are justa as many if not more so that think it is not. The opinions of scientsts is just opinion. If you think that a single cell is a human being then produce a single cells that behaves like a human being.
This is a dishonest argument. You completely ignore that there are entire organizations of medical professionals that do not see a single cell as a human being and therefore are for abortion.

Senator Specter, members of the Committee, thank you for inviting me to testify before you. My name is George Daley. I am here today representing the American Society for Cell Biology, a professional society of nearly 12,000 basic biomedical researchers in the United States and 50 nations around the world. I am Associate Professor of Pediatrics and Biological Chemistry at Boston Children’s Hospital and Harvard Medical School, the Associate Director of the Stem Cell Program at Children’s Hospital, a member of the Executive Committee of the Harvard Stem Cell Institute, and Board Member and President-elect of the International Society for Stem Cell Research (term to begin June 2007). .......
Science certainly cannot define when in the gradual course of human development we deserve individual and autonomous rights. I do not agree with the premise that the single celled zygote should be given the same considerations as living persons and I do not view the embryo as a human being, particularly when it is frozen in a freezer.

This guy is speaking for the American Society for Cell Biology, nearly 12,000 scientists. He is not just speaking for himself.
This appears to be a cheat sheet for pro-choice people who lack the intelligence to form their own arguments. In any case it is not evidence of anything other than people argue about this. But then I already knew this.
This is a repeat of a previous link. I guess you thought you didn't have enought links so you decided to post links that repeat the same information. So what?

There is no point from fertilization until death when, biologically, the human nature of that human being is altered. That human being continuously creates specifically human enzymes and, once formed, is on a path to grow and develop in the natural course of human growth. As we’ve said, all he or she needs is nutrition and a warm place to grow.

This is characteristic of the argument of why an embryo is a human being. For some reason they completely overlook that simply because there is a human cell at the beginning that has the basic machinery of all other cells in a human being that therefore they are the same. It completely ignores that what makes a human being a human being is not the enzymes that cells use but the number, kinds and arrangement of the cells that makes a human being. I am always amazed that this point just eludes them.
No one is claiming that a single human cell does not develop into a human. In fact because it does undergo the transformation as shown on that website the beginning cell is not the final product. If it were there would be no need for that process to take place in the first place.
Again no one is claiming that it doesn't develop into a human being, just that it doesn't start off as a human being.
