think so too and would be willing to start.

Direction doesn't imply anything about knowing which way to
go. If you want to define the word this way, then it's your

Evolution is a random process of mutation and

Mutation doesn't have direction if the density function is
symmetric. If not it has a direction. Selection certainly
has a direction.

I can understand why you would want to defend this point of
view. If you don't we'll ask you to show the scientificity
of your science by making predictions. Don't worry, I won't.
