Some creationists have told me that common structures in almost all animals, such as eyes, lungs, heart(s), kidneys, etc., are proof of a common creator. As an evolutionist, how do I respond to this?

I have a theory concerning this but I first want to make a comment concerning this. Besides math principles being discovered every 100 years or so, math basically remains the same. It stands to reason then why something that seldom changes should be so difficult to learn. Now for my theory: I believe that Americans do poorly in math primarily because of the way it is being thought. No one has analyze the way two people interprets and understand the same thing being taught to them. People who do well in math more than likely interprets and process information very similar. Saying this, why hasn't some cognitive psychologist or researcher found some revolutionary solution to this problem or in fact anyone?

I need to digest a vector (single digestion, sticky ends) and dephosphorylate before ligation with the insert and then transformation into E.coli. The problem is I don't have much of the vector to begin with (v. low yield) and I keep losing alot of DNA in purification. Do I absolutely need to purify between digestion and dephosphorylation? And do I really need to purify again before ligation? I've heard it's not neccessary, but what about the mix of buffers you get? I'll heat inactivate the RE, but do I need to do this with the AP? Any suggestions would be appreciated.

What is Charles Darwin's theory of natural selection and evolution!?

Why are there so many different species today? For example, why is a crow more alike to a magpie, than it is to a Bush stone curlew? Did it have a different common ancestor to the Bush Stone Curlew? Answer either/both please...
