May 4, 2012

[font size=3]There must be something in the warm breeze. A study on bats suggests that bats produce twice as many female babies as male ones in years when spring comes early.

The earlier in the spring the births occur, the more likely the females are to survive and then reproduce a year later, as one-year olds, compared to later-born pups, according to Robert Barclay’s research published in PLoS ONE.

“The early-born females are able to reproduce as one year olds, whereas male pups can't,” explains Barclay, professor in the Department of Biological Sciences.

“Thus, natural selection has favoured internal mechanisms that result in a skewed sex ratio because mothers that produce a daughter leave more offspring in the next generation than mothers who produce a son.”

3. That's like saying evolution is in control

And that evolution has at least some control in what happens next.

Heck that's almost religious..!!!
