No, it's not feasible at all, because "purpose" and "means"
requires the existence of a volitional being to have a purpose
and to choose means. To assume that evolution has a purpose
is a contradiction in terms: it is theism. Evolution, when
understood correctly as simply an inevitable mathematical
consequence of certain initial conditions, explains precisely
how their can be such wonderfully conplex things as people
and viruses which /appear/ to be designed for a purpose
without requiring the existence of a designer or purposes.
It's really not that difficult a concept once you put your
mind to it. Dawkins is, of course, one of the best explainers,
but it really was Darwin who made the important conceptual
leap that made it possible once and for all to get rid of the
silly ideas of "God" and "nature" that kept us in the dark.
