We all like to think we know stuff, don’t we? There is nothing more satisfying than being able to drop a few facts into a conversation and sit there with a smug grin while everyone looks at you in awe of your apparent wisdom. Well what if we told you that some of those facts were wrong? We have put together a list of some of the so-called facts we all thought we knew, but have recently been proven wrong. Quick, get your pen and paper out, you might want to take notes!
Chameleons Change Colour For Camouflage
Em…they don’t. They do change colour, that much is true, but it is not to blend in with their surroundings. Their reasons for colour-changing are actually more to do with communication with other chameleons and also to help maintain body temperature.
Dinosaurs Were Scaly
It was once thought that these great beasts of the past were giant scaly monsters. It was thought that their skin resembled that of the lizards we are familiar with today. However, recent discoveries suggest that over 30 species of non-avian dinosaurs actually had feathers. This has been proven either from direct fossilized evidence of feathers, or other indicators, such as quill knobs.
Humans Only Use 10% Of Their Brains
The origin of this myth is unclear, however it has been attributed to Einstein in the past. Despite scientists being repeatedly outspoken about this, it seems to linger on. While we do not use all of our brain all at once all of the time, we certainly do use all of our brain.
The Great Wall Of China Can Be Seen From Space
It is a rumour that has been circulating for decades, however, NASA has confirmed that, while there are many man made objects that are observable from space, The Great Wall isn’t one of them.
Camels Store Water In Their Humps
Again, unsure where this one started, but they do not store water in their humps. What they do store however, is fat. They use this fat as nourishment if there is no food about.
Goldfish Have 3 Second Memory Spans
This is one everyone has heard. However, in 2009 a team of scientists set out to disprove this theory, and disprove it they did. Through various experiments they proved that goldfish can remember things well past 3 seconds, and can even remember things for a few months.
Blood Is Blue Inside Your Body
This is a well known myth, although some of you may be surprised. It is said that because the veins are blue and they carry deoxygenated blood, that the blood itself is blue. This is untrue however, as blood is red regardless of how oxygen rich it is.
Sugar Makes Children Hyper
Many studies have proven this to be a myth. Tests conducted as far back as 1994 show that there is no proof that sugar will make your child hyperactive. Various other ingredients found in candy can have an effect on your children’s behaviour, though, and sugar is certainly not good for children.
Cracking Your Knuckles Will Give You Arthritis
This is completely untrue. The popping sound you hear when you crack your knuckles is in fact a displacement of air in the joint or supporting ligaments.
So now you know, things you thought to be true are not, dinosaurs had feathers and you can crack your knuckles to your heart’s content! It just goes to show that science is continually changing and we are learning, disproving and proving things all the time.
