why is there salt in the sea?and if there was a planet similar to ours in space would it be possible that the only difference was it had fresh water seas?and would the creatutres and speices that evolved from it be different to what we belive of our evolution and origin because of the lack of salt?

Your question is quite interesting... in there were freshwater seas it would propobly be a lot like our big lakes the creatures in them. http://www.sciam.com/askexpert_question.cfm?articleId=000B9991-6E9C-1C72-9EB7809EC588F2D7&ec=ypi

Salt is just chemicals that wash out of rocks over very long time frames. Another planet like ours would have some rocks but it is possible that it might have more water or less salt. Life could probably evolve but it would likely be different. All animals beyond bacteria keep a saline solution in their cells. We depend on it but some other mechanisms could theoretically evolve in a much less saline environment.
