Mitochondrial Eve

Microbiologist Dr. Doping tells about Y-chromosomal Adam, structure of the mitochondria and genetic drift. When the concept of Mitochondrial Eve was introduced? How is the transmission of mitochondrial and Y-chromosome from parents to children? When supposedly lived mitochondrial Eve? And is it possible to establish the origin of the individual on the mitochondrial DNA?

About 15 years ago, geneticists have come up with the term "mitochondrial Eve", and applied it to some logical construction, which showed that all people alive today are descended from one and only one woman was named Eve. Similarly, we can show that all men are descendants of one existing today. This man is called the Y-chromosomal Adam. The fact that scientists are talking about Adam and Eve, he immediately led to perturbations in creationist circles and others who suddenly decided that science has thus finally proved that a literal interpretation of the Bible - it is right and good.

We are all products of our mother's ovum connection with the sperm of our father, and at the same time it is clear that there are two sexes - male and female. Sex determination is as follows: women have only one type of germ cells, they contain only sex X chromosome, males have two types of sperm - with the X chromosome or a Y-chromosome. Accordingly, when connecting the egg and sperm can be produced version of the XX - it will be a girl, and can be obtained XY option - it's a boy.

We like organisms are not the subject of evolution, because we ourselves do not pass; we give only their genes, our genes are the subject of evolution, genes evolve in us. Each of our genes tries herself to all other combinations of genes that appeared randomly created our body. And these genes we pass on to their children, some other combinations, and not themselves. Therefore, genes evolve, there amazing, "Eve," "Adam" and others, it is actually some kind of mental constructs, not actual people; and the people here are almost innocent.
