Sexual Prowess

OK-OK, before you start screaming bloody murder for my use of words, read the rest of the post.  It appears that scientist have proven that the male obsession with size is universal.  Yep, you’ve got it right, Humans down to chickens are self-conscious about size.  What’s your say?  :-)

The male obsession with size appears to be universal, according to a
new survey of animal species where males use ornamental body parts to
attract females. The study showed that sexual ornaments – such as
antlers or a peacock’s feathery display – become disproportionately
large as body size increases.

Most
body parts grow proportionally with the rest of the body as individuals
of a species become larger, although scientists have long known that
visual cues of reproductive prowess are a special case.

Now,
in the largest survey to date, James Brown at the University of New
Mexico, Albuquerque, US, and his colleagues have examined the
proportions of 284 ornament-bearing species to see whether the tendency
was truly universal. They found that in virtually every case, ornament
size grew by roughly the square of the overall growth rate.

Surprisingly,
whether the ornament also functioned as a weapon made little difference
to its size. But even for purely decorative ornaments, dedicating
energy and nutrients to growing larger ornaments rather than overall
body size makes good evolutionary sense, Brown says.

Large
ornaments are more effective at attracting females than a slight
increase in body size. "It indicates that the male with the bigger
trait had more resources," he says
