Of all the things that define us as humans there is surely one remarkable thing that marks us out from other life on earth – language and the ability to communicate via speech. But what is it in our genes that allows us to do this?
On the face of it there seems little hope of working out precisely how a 75ft long, 50 ton Brachiosaur fed itself. However it is possible to make a few guesstimates, by assuming the present laws of physics and chemistry applied 65 million years ago.
Chimpanzees share about 99% of our DNA, making them our closest living relatives, so the questions might be better re-phrased as “Can chimps speak?”
Insects, scabs, rashes, and even dust can all create the insatiable desire to scratch! Even conditions such as depression or obsessive-compulsive disorder can create this same sensation. Scratching your own body is rather an odd thing to do, so why exactly do we itch?
A team of German scientists examining material from the seabed beneath the Pacific Ocean believe that they may have uncovered explosive evidence of an event that altered the evolution of humankind.
We’ve known for some time now that primates, such as Chimps, are able to use primitive tools. However there are other animals that use tools, one of which may completely surprise you…
It was Aristotle who defined the five senses: touch, taste, smell, sight and hearing. But in the last several decades, the definitions of these senses have begun to tangle. Some studies even suggest that 1 in 5 people can ‘hear’ a flash of light.
Whether you are sitting still for hours, perhaps with your legs crossed, or wake up sleeping on your arm the “wrong way,” you have no doubt experienced pins and needles – sometimes referred to as your leg “falling asleep”. Though this pain soon alleviates itself – what is happening in your body to cause such an irritating sensation?
Bats are well known for employing sonar to find their way as they fly in the depths of darkened caves. What you may not know is that this highly evolved location finding mechanism, also called Echolocation or sometimes ‘bio sonar’, is actually used by several kinds of animals
Ants can form colonies that range in size from a few dozen predatory individuals living in small natural cavities to highly organised colonies that may occupy large territories and consist of millions of individuals. They clearly work together in a highly organised way – but how do they communicate – how would they tell freind from foe?
There’s one popular misteaching that seems to pervade : it’s our understanding of ‘the senses’ – and that is that there are only 5 of them. However if you really think about this subject a bit, its pretty obvious and quickly apparent that we have many more ways to sense the world
You’d think that being surrounded by the stuff that slakes your thirst that you would never get thirsty – but is that the case – Do Fish get thirsty?<
The five-second rule holds that it’s okay to eat an item you dropped on the ground, as long as it was there for fewer than five seconds. But is it actually okay?
No this isn’t one of those crazy headlines beloved of certain ‘newspapers’, (think Sunday Sport : “WWII Bomber found on the moon”, then months later, “WII Bomber vanishes from Moon”), this is in fact a curious, if not slightly frightening, reality.
