Re: another rather typical misconception
It seems to me an example of this can be found in Douglas Futuyma lactose digestion experiment with bacteria, as described in Ken Miller's pointing out of how 'Irreducible complex' systems can evolve.
The experiemnt cuts one of the 3 genes needed for lactose digestion from bacteria, so you have a culture that can not digest lactose. After many generations and letting it grow to be billions, you feed it nothing but lactose, and some of those bacteria survive. They developed , through mutation, another set of 3 genes needed to digest lactose

While talking about how Intelligent Design got it wrong, it also is an example where you have to have multiple traits develop at the same time to provide new function.

Re: another rather typical misconception
So, but it had to be three distinct mutations.
And that was just a very minor thing. There is not reason why more complicated structures could not form, particularly if the changes were accumulative.

Re: another rather typical misconception
As is the electric eel, when you take into account account accumulative change over time, with the filter of the environment the eel was in.

Re: another rather typical misconception
Does it??
Do we know all the factors involved in it? You are making a lot of assumptions there based on lack of knowledge.
It could very well be at least primitive life is assured in the proper conditions. After all, chemistry follows strict patterns.

Re: another rather typical misconception
We have enough factors to make equations to estimate, e.g., the amount of time it will take for a particular complex adaptation to arise.
Do you?? Care to back this up with a source? Let's see the calculations and the claim. Let's see who is making that claim, and their qualifications.
It's easy to make claims.. it often is harder to back them up.
