I'm not sure what to say here. It sounds like you're mistaking the theory of "mitochondrial Eve." I'm a little fuzzy on it myself. Essentially, the argument is that she is the earliest (meaning oldest) version of some genetically comparable arrangement to modern humanity. I take that to mean, given that the Cylons were 2-to-1 female to male, most of the babies born half-and-half would have Cylon mitochondria. Which is why Hera would be the Eve--the first to have those and the human traits that make her similar to present-day human/Cylon people. So she is important so far as being a pathfinder, even though it is safe to assume she was far from the last half-Cylon, half-human child.

The "Hera is important" meme is still valid in that reading. However, as I said on your blog, it would have been MUCH more important to look to Hera as the shape of things to come had humanity and Cylons depended upon her as the model for their mutual society that was aware of the difference she represented far into the future. That is not what we got. What we got was a chain of descendants who have no idea that they're part robot. As such, they have no idea that building robots more and more "human"-like is a troublesome development. I think that's bullshit. Hera would have been much more important for the fact that humans and Cylons both remember her as the first to mix their species and create the new future if they were still aware of it. Instead, she's nothing more than a blip on the evolutionary radar, her spiritual/emotional significance long lost to time. This is what happens when you destroy your history along with your tech...
