DNA Facts - Did you know?
The human genome is composed of all of the DNA found within the nuclei of our cells. However, there is another source of DNA within our bodies. Mitochondria are the powerhouses of our cells. It is thought that mitochondria are actually simple cells that invaded our cells at some point in the distant past. This has been suggested because the mitochondria maintain their own DNA and replicate on their own. When an embryo forms, it inherits half its genome from its mother and half from its father. But all of the mitochondria are from the mother’s egg. If a mutation has occurred in those mitochondria, then all of the resulting offspring’s mitochondria will be mutated. This is often deadly. To stop this from happening, a potential treatment has been developed which would essentially create a baby with three parents.A sperm would fertilize the mother’s egg as normal, but then the nucleus that is formed would be removed from the embryonic cell and placed in an egg that has had its nucleus removed. This cell would therefore have the DNA of its mother and father, and the mitochondria of a third person as well.
Surprisingly, there is less genetic diversity across the entire human race than can be found in a few dozen African monkeys.
From this we can speculate that the current human race evolved from a very small group - also known by scientist as as a genetic bottleneck.
We can conclude that at some point some sort of natural catastrophe or climate condition wiped out a large percentage of the prehistoric human population, leaving a small group of survivors from which modern man evolved.
