@Dan From Smithville , why did you mention Lenski? Apparently you overlook what I said....
Has the LTEE produced de novo
anatomical features? That’s what I said, you know. Was that an attempt to move the goalposts?
Please don’t misrepresent what I say.
YOU are moving the goalpost.
Your initial request was about de novo
functions. Not anatomical features.
Although I could argue that a combination of multiple mutations opening up an
entirely new metabolic pathway, is an entirely new anatomical feature concerning metabolism.
In any case, I'm guess that by "de novo anatomical feature", you mean something akin to a forelimb evolving into a wing suited for flight or something. Which would be a process that necessarily would take millions of years and thus by definition not possible to observe in real time, as the entire process takes even longer then humans in general have existed.
So perhaps this is a good time for you to narrow it down and define properly and in detail, what it is that you would want to see as evidence in support of evolution exactly.
I predict that you can't do that for any of the following two reasons:
- you can't, because you deliberatly keep it vague so that you can simply dismiss any example presented with the excuse that it isn't what you asked for, without ever actually being clear about what you are asking for.
- you can't, because the model of evolution you have in your head, is actually a strawman. Being detailed about what you wish to see, would expose that as chances are rather big that the example that you would wish to see, would actually end up
disproving evolution rather then support it.
But hey.... you can easily prove my prediction wrong by:
- actually give a detailed and clear description of the example you wish to see
- being sure that this example indeed fits withing the evolutionary narrative and not some strawman.
I actually hope that you give this an honest attempt that proves my prediction wrong.
