Richard Dawkin's big blunder

[JuliaL]

Where on earth do you go to observe an evolutionary system come into existence?....You have to go to where intellects are making them because they just don't come into existence on their own. Now you would have me believe this one system did come into existence without substantive involvement of an intellect? Why should I believe that?

Because plausible mechanisms have been proposed (RNA world) which would explain the kickoff of the world's longest lasting unbroken organic chemical reaction. Your observation that we haven't seen new systems of replication with variation arise without intentional intervention is moot if the only intellects we have ever witnessed are the result of natural, unintelligent, processes.
I'd rather say that in the production of replicating, evolving systems, intellect is sufficient but its necessity is unproven.

In answer to the OP point about convergent evolution:
Convergent evolution requires intelligence to guide it as much as rain requires intelligence to find the river which takes it back to the ocean. Intelligence might do the job, but gravity is the simpler explanation.
