Okay /sci/ I'm not very smart with the whole science thing but I was just wondering what to say when Creationist says "genetic mutations don't add information to the genome".
okay, thanks.

lol, i was literally just about to post this, i actually have that link as my CTRL-V right now...

to add:
genes can duplicate, and a gene that has a certain fucntion might be like a 'jack of all trades' effect, that is fairly good at doing multiple different tasks.
when this gene is duplicated, the information is there twice, and mutations can happen independently
slowly over time, one of the genes can alter, and have a new function, with the other one staying the same. you might have a bacterium capable of creating a new protein that it couldnt before, and yet it hasnt lost the old function, because a gene still exists for it.

it is now more complex, because these are now 2 completely different genes, that are mutating seperately.

as in, 'jack of all trades, master of none' does 2 functions, but neither one of them particularly well.
after gene duplication, the 2 functions diverge, and they become 'master craftsmen' at 1 specific task, seeing as they have the other gene already in the genome that can cope with a loss of function in one aspect, and so can specialise

Ask them for the bible's explanation of transposons and pseudogenes.
