Are you guys that dense? You think I said every creature or any creature is exactly the same as another?
Unbelievable. It's like talking with children or something.
The idea is not that there are exactly the same as they can't be since they have different reproductive organs. The idea is why are the same designs repeated in the pairs when there is really no environmental reason for that to be so.
Moreover, the point you guys are really missing is that either way, my original point stands. You cannot have a theory that predicts all possible outcomes and it still be good science. You cannot say, well, if there are similarities are theory is it must be common ancestry, but if not, then our theory says it's convergent evolution. That's not a proper use of data.
You could say maybe it's like this but you need to admit you are undercutting your theory in the process.
Besides you 2 didn't even get the ad hoc comment directed towards another when he was bringing up gene regulation. It's a whole different issue and debate, and one I doubt you are familiar with.
