No I personally can't but I can find plenty resources that contain the answers.
Got to go check with the "Elders" eh?
Well, you have my permission to cut and paste the BEST ANSWER you can find. We are all depending on you: Here's the question again:
Challenge Question: Can you explain (in your own words) how caterpillars and butterflies came to be, using only evolution principles such as random mutations, small incremental changes, and natural selection?
In other words, which evolutionary process would prompt an organism to digest itself into goo? Then, which incremental processes and environmental pressures would then prompt the goo to develop new organs and a new body... not to mention the added capability of flight in a beautiful display of colors and designs?
Get me a personal message from your imaginary professor friend inviting me to meet with him.
Moving the goal posts eh? No way. He has an open invitation to "anyone". That includes you. Here is a quote from him:
I posted on my Web site that I don’t understand. And I said, “I will buy lunch for anyone that will sit with me and explain to me evolution, and I won’t argue with you until I don’t understand something – I will ask you to clarify. But you can’t wave by and say, “This enzyme does that.” You’ve got to get down in the details of where molecules are built, for me. Nobody has come forward. - Professor James Tour
You agree first. Then, I will try to set it up. That's the deal. If Simon will reinstate my ability to start posts, I will keep everyone posted on the developments with a thread dedicated for that purpose.
Dr. Tour, like the rest of us would like molecules-to-man evolution explained.
