I would love if someone could answer these questions for me
1. Does the Human Genome project list all of the mutations that led to us how we are now?
2. Could someone explain in detail about the mitochondrial eve. I saw a few people trying to explain it in kdbrich thread but im still kinda confused about it. Would love it if someone can explain it to me in detail.
3. Are we not the result of incest? Kinda confused because at one point in time, didn't family members have to have sex with eachother??(hope that question makes sense)
Would love for someone to explain these questions to me in further detail!!

As far as I know, the HGP is a 'map' of the 'current' human genetic code. We don't know what all the genes do, but thanks to the HGP we now have a general idea of what each gene consists of and how it works chemically.

I can't go into great detail (primarily because I don't know a lot about it), but here it is in a nutshell:
Mitochondria are, in essence, a record of our 'dormant' DNA and RNA from pretty much the beginning of human evolution.
'Mitochondria Eve' is the genetic 'Matrilineal Most Recent Common Ancestor' (MCRA) for all modern humans. Since mitochondria are passed matrilineally, it's simply a matter of tracing backwards until you reach 'Mitochondrial Eve'. It's the same for all of humanity, back to the dawn of homo sapiens sapiens*
*No, that's not a typo -- it's an extremely short form of our 'actual' (much longer) species name. It means 'Wise wise man' (which is both redundant and ironic).

That, I'm afraid, I'm not qualified to answer -- though, if we ever find a 'Mitochondrial Eve', it may help to explain that part of the 'human story'.

I am not a scientist, and could not even begin to answer your questions. Incest is a relatively modern word.
My belief is that humans were in a greater state both mentally and physically than their descendants. The bible says that Adam was a perfect man, and likewise, Eve. How else could they have procreated than by marrying one another?
This seems a thousand times more plausible explanation for our existence, and all the wonder it entails than an 'amoeba soup' theory.

1. No
2. Google
3. Yes, incest happens everyday, sorry if you don't like that, I have problems with it too, but it happens, and it did happen, and it will happen, in all species.
No matter how you cut it (intelligent design, the book of Genesis or evolution, at some point the only way for the species to have developed would have been through interbreeding.

No it's not. The human race would have died out very quickly if that were true...One pair is not enough to establish a population of any kind, not humans or any of the animals god supposedly created pairs of. The earth would be devoid of life if the creation myth were true.

Your last statement is not true. That's not the way evolution works. Evolution occurs over populations.
If population A is comprised of 20,000 individuals. Something happens, and that population splits into two daughter populations - Pop. B and C, each with around 10,000 individuals. These two populations, if they do not interbreed, will continue to evolve in divergent pathways. Population B could be the ancestors of humanity, while Population C could be the ancestors of chimpanzees.

I'm not the best versed on this but I do have a bit of background knowledge.
First off, we all know what a cell is:
Every single one of us have billions of cells and these cells each have the equivalent to organs(organelles) which allow the cell to create proteins, replicate themselves and even self destruct if necessary.
A very important organelle is the Mitochondria/Mitochondrion which creates most of the energy the cell uses by making ATP(energy dollars) from respiration. As you can imagine, pretty much every eukaryotic cell has them and cells which use a lot of energy like the ones our livers or our eyes have a lot of them.
When it comes to eggs and sperms, they each carry half of the chromosomes(23) that makes a person(46). If you received 2 X chromosomes, then one came from your dad and one from your mom. For example. If you have a child, then there is a 50/50 chance that their/one of their X chromosomes came from the grandparent or the grandmother. With all the genes, it becomes really hard to trace back people's lineage on genetics alone because there really isn't a sure fire way to tell where each gene came from.
But Mitochondria has a very unusual property: It has it's own DNA which is different that what you find at the nucleus of the cell it is in.
Now, we don't inherit mitochondria from our parent's, the mitochondria in sperms is thrown out along with the entire tail of the sperm as soon as it penetrates the egg. We exclusively inherit mitochondria from the egg which means that the DNA in our mitochondria could only have been passed inherited from our moms and their could only have been inherited by their moms and so on and so forth until thousands of generations back. Because of this simple fact, we can trace back our entire lineage to a single ancestor(mithochondrial eve).
I'm not sure why some people think she was the only human female to ever live though. She wasn't, mithochondrial eve just means that she is the person all of us get our mitochondrial DNA from.
The bible says that Adam was a perfect man, and likewise, Eve. How else could they have procreated than by marrying one another?
If they were perfect, they wouldn't have fallen from grace.
