- You Can't Teach an Old Dog New Tricks [img=http://animal.discovery.com/tv/a-list/creature-countdowns/myths/images/dog.jpg] Just because a dog is approaching its more senior years doesn't mean it can't learn a new thing or two. In fact, with approximately 15 minutes of training every day for two weeks straight, even the most stubborn dog can usually learn how to sit, stay, fetch, roll over or whatever your heart desires, regardless of age. The saying is meant to be taken less literally about dogs and more about people specifically, the types who have been set in their ways for so long that changing their behavior would be (to quote the rock band Chicago) a hard habit to break. MYTH VERDICT: FALSE. - Are Hens Teeth Really Rare? [img=http://animal.discovery.com/tv/a-list/creature-countdowns/myths/images/hen.jpg] This expression may not be all the rage among the Gen-X, Gen-Y or Gen-2.0 crowd, but there was a time when it was commonly used to describe something very difficult to track down or find. The saying harkens back to long, long ago, as in 150 million years, back when the hen's ancestor the archaeopteryx was roaming the world. This chicken of the Stone Age came equipped with feathers, claws and a beak full of cone-shaped teeth. Scientists not only recently discovered that hens still have the DNA necessary to grow a set of chompers, but actually successfully put the theory into practice. MYTH VERDICT: FALSE. - Do Camels Really Store Water in Their Humps? [img=http://animal.discovery.com/tv/a-list/creature-countdowns/myths/images/camel.jpg] A camel can survive seven days without water, but not because they are carrying large reserves inside their humps. They're able to avoid dehydration that would kill most other animals, thanks in large part to oval-shaped red blood cells (vs. the standard circular variety). As far as that hump goes, it's nothing more than a big mound of fat, though a useful one at that the lump provides camels with the same amount of energy as three weeks of food. If there's any body part that excels at retaining water, the award goes to the camel's kidneys and intestines. These organs are so efficient that a camel's urine comes out thick as syrup and their feces is so dry, it can fuel fires! MYTH VERDICT: FALSE. - Do Earwigs Live Inside Your Ears? [img=http://animal.discovery.com/tv/a-list/creature-countdowns/myths/images/earwig.jpg] If the mention of an earwig makes you shudder or think of that horrifying scene from Star Trek II: The Wrath of Khan, rest assured while earwigs are predisposed to hiding in warm, humid crevices, they're not likely to choose your ear as their new home. Even if one did, it wouldn't get very far there's a thick bone in your ear canal to block it from burrowing into your ear and laying eggs. So how did this creepy crawler get its name? Turns out if you stretch one out, it actually looks like an ear ... but who has the time for such antics?MYTH VERDICT: FALSE. - Do Lemmings Commit Suicide? [img=http://animal.discovery.com/tv/a-list/creature-countdowns/myths/images/lemming.jpg] The lemmings earn the top spot on the myth list because the misconceptions about these critters are both legendary and long-standing, starting back in the 1530s when a geographer proposed that they fell from the skies during storms. These days, the most popular rumor is that lemmings commit mass suicide when they migrate, but the truth is much less dramatic. Every three or four years, their population drops to near extinction only to skyrocket again, but the ebb and flow is a result of migration in large groups, which can include jumping off cliffs into the water and swimming great distances to the point of exhaustion and even death. The myth was also fueled by the 1958 Academy Award-winning documentary that showed the lemmings leaping to their deaths, but the scene was later busted for being staged. MYTH VERDICT: FALSE.
