Climate change could be disastrous for some animals, but male gray seals are probably not complaining it has improved their sex lives.

Weaker males would not normally have a chance with the females, who usually go for the more dominant types.

But lower rainfall levels have forced female seals on the remote Scottish island of North Rona to travel further from their partners to find fresh water, giving the weaker males more opportunity to mate with them...............

Twiss and scientists from the University of St Andrews in Scotland recorded a 61 percent increase in the number of males contributing to the genetic pool.

"These findings show that climate change, whilst endangering many species, could also help to increase the genetic diversity of some species," Twiss said.

If I fly the coop some time
And take nothing but a grip
With the few good books that really count
It's a necessary trip

I'll be gone with the girl in the gold silk jacket
The girl with the pearl-driller's hands
