Shock the monkey!
Monkeys scream code words.
Klaus Zuberbuhler of the University of St. Andrews, UK has found that putty-nosed monkeys use vocal language in order to communicate with members of their troop. His findings are being published in the May 18th issue of Nature.
These african rainforest monkeys were seen and heard making two distinct calls in order to warn each other. The dominant male was put in charge of warning the others of two main dangers: eagles and big cats. If he gives a loud "pyow" warning, the monkeys flee up the trees to flee from an oncoming tiger or leopard. If his warning is a "hack" vocalization, the monkeys get down from above to keep from getting skewed by an eagle's sharp talons.
Interesting, when the female lets out any vocal warnings, the males continue to fatten themselves with bananas and coconuts, and ignore the call. Scientists noticed this occured most often on Sunday or when it was time to take out the trash. Scientists also heard the monkeys screaming "doo-bee" and I believe that's to warn the others of poop being flung.
Monkeys are chicken too.
M. Keith Chen, Venkat Lakshminarayanan, and Laurie R. Santos recently published an article in the Journal of Political Economy in which they studied the behavior of capuchin monkeys in order to learn more about how humans develop risk-aversion types of behaviors in economic situations.
They presented the monkeys with two different types of payoffs:
1) Spend a token on one piece of apple presented to them, but half the time the monkeys were given one bonus piece of food
2) Spend a token on two apple pieces, but half the time the monkeys got gyped and only got one piece of food instead
Economic theory dictates that consumers shouldn't really care which way to spend their tokens, since the outcomes are 50-50 shots at one or two pieces of delicious apple. However, the monkeys displayed risk-aversion behavior and overwhelmingly spent their tokens using payoff #1. Like humans, the monkeys weighed the chances of LOSS more than the odds of GAINS. In other words, they played the game to not lose instead of playing the game to win.
Also, many of the monkeys threw tantrums often seen at Wall Street and casinos when they only got one apple slice instead of the two they were shown. Yup, you guessed it, they flung their poop when extremely frustrated with the gamble.
Hot monkey sex?
Scientists have been studying the human genome, and comparing it to various apes. They came across a surprising and shocking discovery:
Humans and chimps might have gotten freaky with one another.
David Reich, a population geneticist at the Broad Institute and Harvard University, used a "molecular clock" in order to trace when humans, chimps, and gorillas' genes diverged. His findings were published May 17th in New Scientist. Tracing the lineage, scientists found evidence that humans and chimps might have mated.
They noted that chimps and humans are nearly identical with relation to the X-chromosome (the female chromosome) and using this molecular clock, it suggests that early humans and monkeys created hybrid offspring 6.3 million years ago.
Does this mean there are humans out there that have this ingrained need to fling their poop?
