Question

Which of the following BEST describes who Mitochondrial Eve was... An African maternal ancestor of all humanity today. A female descendant from Africa. The only female that lived in Africa many years ago. A female that is our ancestor from Asia. The first female to migrate out of Africa.

Answer 1

In human genetics, the mitochondrial eve is the most recent woman from whom all living humans descend. Based on studies the maternal ancestor of all living humans -- confirms that she lived about 200,000 years ago. The results are based on analyses of mitochondrial DNA. Found in the energy-producing centers of cells, mitochondrial DNA is only passed down the maternal line, and can be traced back to one woman.

While most of an organism's DNA is contained in the nuclei of its cells, mitochondria also contain genetic material, but much less of it, making it easier to analyze. Mitochondrial DNA contains a region that changes rapidly and can provide a sort of molecular clock calibrated to times comparable to the age of modern humanity.

200000 years ago- Modern Humans Evolve in Africa

During a time of dramatic climate change, modern humans (Homo sapiens) evolved in Africa. Like early humans, modern humans gathered and hunted food. They evolved behaviors that helped them respond to the challenges of survival. The first modern humans shared the planet with at least three species of early humans. Over time, as modern humans spread around the world, the other three species became extinct. We became the sole survivors in thehuman family tree.

So the answer is option a.
