- Yep, but there are *two* (or more) levels of purpose involved.
-
- The *current* purpose of the parrot syrinx, as it is used by wild parrots
- is one of these. This is a *real* purpose (even if there is no intent involved).
- I tend to read a statement like the above as refering to this final purpose.
- [It is certainly *maintained* in its current form because it performs this
- purpose for the parrots, so the purpose is even, to some extent, influencing
- the evolution of parrots].
-
- Yes, you are right, evolution does *not* anticipate, there is no goal to
- evolution itself, beyond the rather trivial one of reproduction. But this
- does not mean that it does not *produce* purpose.
