With 97% of the earth's water being saltwater, and survival of the fittest, why didn't humans evolve to survive on saltwater instead of freshwater? If we evolved from animals that crawled out of the sea, didn't they survive on saltwater?

I keep seeing creationists talk about "The Missing Link", and insist that such a thing has never been found.

What, specifically, are they looking for?

Are they simply ignorant of the fossils in the links below (the boring alternative), or is there something *specific* they're looking for that we haven't found? And what could it be?

...for some time now and am desperate to get out, but need not to have a major drop in my salary (17 k) .I am a head chef at the moment and would love to maybe combine my love of cooking with my degree. Or do lab work, but this is hard to get into without doing voluntary work. I live in the West Midlands, England and would need work within 80 miles of here...

During a healing process, our cells divide to repair a damaged area of our body. Telomere sequences are therefore shortened by this process, reducing the lifespan of the newly created cells.

Theoretically, could this be avoided by enabling the telomerase gene in the cells as they reproduce and then disabled upon successful completion of the process or would it be impossible to disable the gene in such a large amount of cells?

(Obviously the cells would need to be monitored to ensure that any defective cells are removed to avoid cancer developing.)

I moved into my new house about 4 months ago. since we moved we've seen our fair share or spiders, maybe about 8 or 9 biggies throughout the house. However, last night i had to kill 3 huge floor spiders in my living room, all in the space of an hour. You know the type, that run really fast across the floor and make u jump. I know this is the time when the big ones come out in the uk, but has any1 else had a bad experience like this, or have i got an infestation? They appear to be coming from behind the telly, and i have wooden flooring, which is perhaps why i notice them. has any1 any tips, im really upset! Boo Hoo :-(

Are people born that way or they choose that path? if people are born that way is there any evolutional advantage toward homosexuality in humanity? why does bible say that its not good?

This is for experts on Evolution theory. Since natural selection remove negative mutations, we should have neutral and beneficial mutation carried forward. Based on what I understand from our body parts/organs everything is of use to us. Is there any thing in our body that is not harmful nor beneficial ?
