Crabs may be able to intimidate other creatures with their claws, but if that’s not enough, ghost crabs will growl at their enemies like a dog. However, unlike our canine friends, crabs make these fearsome noises using teeth located in their stomachs. “There are three main teeth—a medial tooth and two lateral teeth—that are essentially elongated, hard (calcified) structures. They are part of the gastric mill apparatus in the stomach, where they rub against each other to grind up
Take another look at those hands of yours. You have two of them, correct? Then why is it that you tend to use just one of these appendages for so many tasks?
Whether you’re a leftie or a righty, the fact that you have a dominant hand at all is a bit weird, according to scientists. After all, having two hands with excellent motor skills would be a real boon for humans.
One theory about why people have dominant hands has to do with the way the brain processes speech. The theory holds that the left brain hemisphere — where the speech center of most humans resides — is more intricately wired than the right brain hemisphere. The left brain hemisphere also happens to control the right side of the body. It’s possible that the extra wiring in this part of the brain is behind the dominance of the right side of the body in right-handed people.
However, researchers have found that not all righties have speech centers residing in the left brain hemisphere. In other words, this theory might not be correct. However, there are lots of other theories that could help explain human handedness.
The truth is that scientists aren’t sure why humans tell lies, but they do know that lying is common and that it is likely linked to several psychological factors. Foremost among these factors is self-esteem, according to Robert Feldman, a psychologist at the University of Massachusetts. Feldman, who studies the underlying causes of human deceit, has found that when a person’s self-esteem is threatened, he or she will “immediately begin to lie at higher levels.”
