I came across a website on many interesting sutff. Check it out if you are free and check it out if u aint.. Special note to the health and science section. VERYVERY interesting..

sme INTERESTING examples..

According to data released earlier this year by the Centers for Disease Control, the probability of HIV acquisition by the receptive partner in unprotected oral sex with an HIV carrier is one per 10,000 acts. In vaginal sex, it's 10 per 10,000 acts. In anal sex, it's 50 per 10,000 acts. Do the math. Oral sex is 10 times safer than vaginal sex. Anal sex is five times more dangerous than vaginal sex and 50 times more dangerous than oral sex. THEREFORE.. ANAL IS MORE DANGEROUS THAN ORAL... interesting eh?


ok.. this website isn everything bout.. u noe.. so..

more examples..

In bees, fertilized eggs become females. Unfertilized eggs become males. Even without a queen, some female honeybees can keep a colony going by laying eggs that fertilize themselves.
Birds do it, too. Up to 30% of unfertilized turkey eggs can spontaneously begin to develop. In one study, selective breeding boosted the rate above 40%. A 1975 U.S. government report documented more than 50 mature turkeys that were never fathered.
Lately, parthenogenesis has been verified in various snakes and lizards, extending the list to about 70 vertebrate species, including fish, frogs, and chickens.
Still, the process hadn't been proved in sharks or mammals. And there seemed to be a good reason why. An egg that fertilizes itself makes two identical sets of chromosomes, including sex chromosomes. In birds, snakes, and most lizards, two identical sex chromosomes make a male. That allows parthenogenesis to function as a DNA survival mechanism, since an isolated female—close your ears, kids—can produce a son and mate with him. But in sharks or mammals, this wouldn't work, since two identical sex chromosomes—XX—make a female.
Or so we thought. Three weeks ago, Biology Letters delivered the second surprise. A perfectly formed baby shark had appeared in a tank in Nebraska. Tests proved she, too, was a parthenogen.
Why hadn't we found parthenogenesis in these animals before? Because we hadn't looked. Several sharks have mysteriously reproduced in captivity in recent years. Scientists now think parthenogenesis is responsible. Of the two sexually mature female Komodo dragons in Europe, both are now known to have reproduced this way. Every parthenogenic dragon is male, which may explain in part why males heavily outnumber females. In snakes, the array of known parthenogenic species continues to grow.
For explaining everyday life—babies, puppies, puberty—the mommy-daddy story of procreation works fine. But at life's edges, conventional biology, like conventional physics, breaks down. As you approach the speed of light, time slows and distances shrink. And as you approach extinction, genes find new ways to pass themselves on. A Komodo dragon manufactures a mate. A shark's got to do what a shark's got to do.
Parthenogenesis is just one of nature's tricks. Female turtles can store sperm for years. Sea bass can change their sex. Hermaphroditic sharks can fertilize their own eggs. Male ants can commandeer eggs to clone themselves. Some lizard species have reproduced for ages with no apparent male input.

INTERESTING EH!? this might probably explain the natural selection theory in biology.. n dat moofoo abt why there are more males then females..

so go chekc this website out!!! http://www.slate.com/
