- On one level, the Eve hypothesis is what might be called "trivially true".
- Everyone has only one mother, though several people may have the same mother.
- Therefore, if you start tracing mother of mothers of mothers of mothers...
- the set of great^N grand mothers can only decrease with N. In order to not
- come up with a single mother of us all, it would be necessary to have at
- some point two women who share no common ancestry *at all*. Therefore,
- barring convergent evolution or divine acts of creation, there must exist
- one woman who is an ancestor of all humans.
-
- Problems for which an answer *must exist* sometimes lead people to develop
- algorithms which will *always* come up with an answer, right or wrong.
- I understand that something like this happened with the Eve problem-- the
- computer program was guarenteed to come up with some answer for any input,
- and if the input was tweaked slightly, the answer changed dramatically.
