wtf

It's complicated but we believe life started in complex self-replicating RNA molecules. From there everything diversified.

Where does the first cell come?

[quickieSS]

@UberShadow666 The first cell ever, or the first cell in a human?

[UberShadow666]

@quickieSS

Well, they say one cell creates the rest.

Just wondering where that one cell came from.

But I'd assume the answer has something to do with the creationism vs. evolution topic, so never mind. :P

[quickieSS]

@UberShadow666 Well, during fertilization, two haploid cells combine to make a zygote. There will be a male gamete and a female gamete.

[Darwin42ME]

@UberShadow666 If by the first cell you mean the origin of life from non-life, you are referring to abiogenesis and it would not be covered by evolution, since evolution requires reproducing life. I don't know a scientific topic that covers creationism.

This class should give you a great intro as to how the chemical processes that took place could of happened, but there is plenty of info out their pertaining to your exact question.

@UberShadow666 dont you know! first cell come from first person came to world and every one knows that first person is HAZRAT ADAM (peace be upon him)

[UberShadow666]

@Aimal1khan :P

And aren't we happy you're staying out of bio! He actually says in the same sentence "...that are *similar* to stem cells..." Although he's only reading someone else's work no one is mistaken but you. There are in fact heart cells capable of differentiating themselves to repair certain damage. These are in fact different than stem cells. Why bother watching if you're not interested in listening, or think you know more than a *MIT* professor?
