I've been pretty busy, but I hope to find time to engage evolutionists here when I do find time. Sorry Mark that I haven't gotten back to you, I realize you have posted a few things that I just didn't have time to address.

No problem Fred.Mark------------------

I actually don't have a problem with the graph. It shows a higher proportion of harmful mutations to beneficial, most are nearly neutral, slightly on the harmful side. As such these will be weeded out in the ns process. Go much further to the left, & potential monkey man simply isn't going to make it out of the uterus alive.This leaves us with the mostly neutral mutations. And a negative mutation CAN be positive in other circumstances (& vice versa, of course).What the graph DOESN'T show us, is where the beneficial line ends. The more it goes to the right the greater the benefit, & the greater the chance that mutation stands of being fixed in the population. All the while the negative ones are being removed.Mark------------------

1. neutral mutation: A neutral mutation would be a change in nucleotide triplet(s) that: a) took place in an intron, and hence had no effect, b) eliminated or modified a redundant codon (again, no effect), or c) produced an alternative form of a gene that made no difference on the efficiency or form of the final product (ex: if the third base in the TCT codon for serine is changed to any one of the other three bases, serine will still be encoded). Since something on the order of 97% of the genome doesn't actually code for anything at all, neutral mutations would tend to be the rule, rather than the exception.

One more for the neutrals. A nucleotide substitution that changes the amino acid coded for. If this amino acid makes no difference to the function of the protein, & it looks like a high percentage of any particular protein doesn't mind which amino acid is at a particular location in the sequence, & will therefore be neutral.Mark------------------
