whiporwill-o 0range_rayne hello my name is rayne, im 26 and i love in florida. ive been learning and reading about witchcraft for almost 12 years now. i love learning about all kinds of stuff and i grab any book i can find. i love to read.. some things i am not good at like herbology and some things i am good at like astral projection.. im usually shy when it comes to talking on the computer to new people, but once i get to know you a little bit i can become quite chatty biggrin i look forward to getting to know this community better.. ~rayne what part or florida, if you don't mind my asking, i'm in south alabama.

Oooh! I know this one! Do you know about mitochondria? Eh, I'll explain anyway. Mitochondria are only kind of human cell components - they're more like symbiotes. They have their own DNA and it's inherited independently of regular old human DNA. Actually, it's only passed down through the maternal line. And it more or less clones itself. So, your mitochondrial DNA (I'm going to start calling it mDNA so I don't have to type it out) looks exactly like your mothers, except for any mutations. Now, we know the rate of mutation for mDNA - it's a constant. So, we can measure the genetic difference between current humans, and from that extrapolate how long ago (how many generations ago) our most recent matrilinial common ancestor was. Most estimates place her between 150,000 and 250,000 BP (Before Present). |

Not quite. There were tribes of people, and it just means that maybe she was someone's aunt, someone's sister, someone's mother and such, and that everyone is related to her. She had a different mother perhaps than her sister, or her cousin. It's a little bit more complicated than the media makes it out to be. It just means everyone is related to her. For the record, something like 1/7 Irish men DNA wise are related to some Irish king, and the same of many people with Khan. It doesn't mean they were full siblings etc, just they shared a common relative. |

Nope, Ultramarine was actually right. The theory states that she was the matrilinial ancestor of every human alive today. We do call her Eve in casual conversation. Of course there were other humans alive at the time, but we're talking about a very small population, at the very cladation of our species, probably less than 5000 breeding females. Their regular DNA is either in all of us or extinct, but they don't have the pure matrilinial line. Note that the matrilinial most recent common ancestor is not the same thing as the most recent common ancestor, which actually occurs several thousand years after Eve - the identical ancestors point is between 5000 and 15000 years BP. |
