[FONT="]still theories not evidence.
Oh dear, look up what a scientific theory is. This is a terrible argument based on your ignorance .
You think nipples have no function in males, but I don't think so and have explained before so there's no need to repeat. Believe what you want to believe.
I don't understand this. Read the other points in the OP, this is only one point.
Because it's an egregious fraud
DNA is so complex that random change can be creative. Mutations have proven to be more damaging than inventive. [/FONT]
[FONT="]Mutation can result in several different types of change in sequences;(DNA) these can either have no effect, alter the [/FONT][FONT="]product of a gene[/FONT][FONT="], or prevent the gene from functioning properly or completely. Studies in the fly [/FONT][FONT="]Drosophila melanogaster[/FONT][FONT="] suggest that if a mutation changes a [/FONT][FONT="]protein[/FONT][FONT="] produced by a gene, this will probably be harmful, with about 70 percent of these mutations having damaging effects, and the remainder being either neutral or weakly beneficial.[/FONT][FONT="][/FONT]

Well, it's a good thing you are wrong, i have studied mutations in Drosophila.
Take the example of sickle cell, this one SNP causes increased resistance to malaria. Although there are bad traits in other environments (such as high altitude). The same goes for us, lungs are good in our environment, but bad under water.
Yes, but phenotypic changes can never covert to genotypes, so the only method for the claimed evolution must be through genotypic mutations which are proven more harmful rather than beneficial. Eventually , the balance of the effect of mutations goes towards destruction rather than creativity even if some mutations are beneficial.
You oust your own argument here. Most are bad, but some are good. The fact some are good is how evolution works. Those ones that are good spread throughout the population. And as i said before, the phenotype is as a result of the genotype (+environment), i think we both agree here.
Yes, if they disuse their breasts ( if u think they had a breast) they may atrophy , however this atrophy can't be printed on genes and transferred to next generations.
I think i may have miss-used atrophy. They decrease in size over generations, as those with bigger 'whatever' and dont use them, are less fit.
Yes, lactation is not useful but that doesn't mean the nipple has no function. The question was about the nipple and I didn't say men suckle infants.
So what advantage does a nipple have to a man? Unless it's an artefact of evolution and development.
Just arguing, You think you've a better design that God's creation so give us a great one. I don' t think it is easy for you to design a new human being.
No, but i would design the man without nipples, and if you have a look at my other thread, about why a perfect god didnt create us perfect, then you will see that there are many logical imperfections in our design (when i say logical, its like walking round 3 sides of a square to get from a to b).
If you would like to design another man of your own so do it. And, we shall see if it's going to better than the current one. There is no scientific research proving that more sex chromosomes will be beneficial. It's just your imagination and fantasy. Try it and show us if it's going to be better. I bet that great problems will arise because God's design is the perfect one.
Please re-read what i was saying. You have miss understood the whole concept of evolution. This is exactly why a designer didn't design us.
Yes a pointless argument, You can't prove that another design will be better. In fact you are comparing a current perfect design to a science fiction.
True, but as scientists can explain why something is the way it is, then we don't need to. Science can explain, using evolution, why men have nipples, etc.
Also, obviously we couldn't build a better human, as we are not infinitely powerful, like the character of God is portrayed.

well, God gave one design because it's perfect for the job and there is no better than perfect. However, chance can't create perfectness and if you suppose chance created this great DNA it should have created before more primitive forms as well *** different compositions than are less perfect but still functioning till reaching the perfect manner.
Anything not the best option at the time will be out competed. Or the new mutant moves to a different niche, causing speciation. Why could chance not cause beneficial mutations, you admit this yourself.
Chance can't start perfect, remember there is evolution and you are ascending ladder steps you can't jump to a supermodel from the first time. In addition, simpler forms of DNA like systems can be formed by chance as well. Why only this complicated form from first time and the only present one in living creatures, DNA and RNA.
Well, a not well functioning central dogma would be replaced by a better functioning one, obviously.
There is no scientific principle preventing something like DNA forming, then using its 'life' properties to improve itself. Also, we are far from perfect.
Did we just jump to the top of the mountain, or did we walk up it, slowly?
The former seems much more unlikely.
