Weird that they're only probably sure they know how reproduction works.

To be fair, the concept of mitochondrial Eve still trips me out.
What is "mitochondrial Eve"?
It’s the most recent common female ancestor of all humanity, as determined by mitochondrial DNA.
Or put another way. If everyone traced their family lines back through their mothers, mitochondrial eve would be the first point where all those lines converged on a single woman
It helps me to remember that mitochondrial Eve isn't a fixed individual, as well.
Imagine being the last (female, strictly matrilineal) descendant of one of her daughters: "If I die without a daughter, the line of Alice will end and that bitch Caitlin will become the new Eve!"
Hell, imagine fighting a secret war to extinguish the other line - now there's a "secret society conspiracy" plot if I've ever seen one.
I'd watch that movie!
There's also a Y-chromosomal Adam, but they lived many thousands of years apart. That seems very counterintuitive, but when it is explained to you by someone who knows what they're talking about (i.e. not me), it does make sense.
Yeah when it's explained to me I realise "of course, that makes so much sense".
And then I forget again, so I'm all Keanu-Reeves-whoa-face next time I think about it.
