Mammalian mitochondrial DNA mutates so quick that it causes a problem known as “saturation”, the place random noise drowns out any information that could be current. If a specific piece of mitochondrial DNA mutates randomly each few million years, it will have changed a number of times within the 60 to 75M years because the main teams of placental mammals diverged.
