There has been a plethora of recently published articles exposing the belief that humans are the evolutionary product of a single female of a primate species forerunning Homo Sapiens, who lived approximately two million years ago. In providing support for this estimated time frame, scientists have noted that since seemingly unrelated humans share, on average, 96 percent of their mitochondrial DNA, they have been able to use the average rate of mitochondrial DNA mutation to extrapolate the length of time that has elapsed since this common female ancestor lived.
Which of the following, if true, provides the most support for the scientist's theory?
By using radioactive carbon-dating, scientists have estimated the age of the oldest discovered primate remains to be nearly two million years.
Mitochondrial DNA is found only in the cells of higher primates such as Homo Sapiens.
Mitochondrial DNA mutation rates vary significantly and are dependent upon a variety of environmental factors, especially those that affect radiation levels.
Many people have less than 96 percent of their mitochondrial DNA in common.
The rate of mitochondrial DNA mutation has been determined to be quite consistent and predictable.
