They studied and analized the mitochodrial DNA in different folks and they discovered we have 8-10 common "ancient mother", who lived in the east region of Africa. Only mother can give mDNS to the next generation, so if you follow back the DNA line you can see where was our genetic past. So BSG referred to this biochemical discovery as Hera was the first. She changed our evolution in BSG's timeline, because she had human and cylon DNA together.
