Identical twins come from the same sperm and egg – and thus have the same DNA – ie EXACT identical genetic makeup. So do they therefore have the same fingerprints? Or to put it another way would twins force Hercule Poirot’s “little grey cells” into overdrive in a murder investigation ?
The film “Jurassic Park” introduced a very interesting concept regarding the possibility of cloning a long dead species from preserved DNA – in this case dinosaurs. Sounds plausible – but is it ?
Chameleons camouflage themselves in a variety of different ways but most famously by changing the colour and pattern of their skin.
Blushing is rather an odd physiological and psychological response to embarrassment or awkward social situations. Could there be any rational or logical explanation for this? What possible evolutionary reason could there be for such a strange phenomenon.
“We no longer have to wonder what self-awareness looks like – we can see it for ourselves” : A bold statement indeed. What we’re referring to here though is that scientists now believe that they can trace where they think conscientiousness physically sits in the brain
We seem to have the exactly the right number to do the job – but why 5 fingers and five toes on each appendage – Why not 6 or 10 on each ? In this article we look at what is believed to be the reason it is “just so”.
As children, many of us learn about the wondrous process by which a caterpillar morphs into a butterfly. The story usually begins with a very hungry caterpillar hatching from an egg. But what does that radical transformation entail?
The human body is a pretty remarkable thing to the point that it actually has several different types of internal clocks that helps to keep us ‘ticking along’ for both the daily and seasonal rhythms of life.
According to the theory of evolution shouldn’t the strongest organism live forever ? …. No. But the ‘answer’ as it stands is rather mind-bending
In the springtime we see migratory birds returning to us whilst in the Autumn we bid them farewell as they head for warmer southern climes. But how do they know when to leave our shores ? – and why do they bother to return again ?
Urban legend has it that if you want to calculate a dog’s age in equivalent human years you should multiply the dogs age by seven. But is this really true ?
The Autumn display of colours when trees begin to lose their leaves is a pretty spectacular thing. But why and how does it occur?
If you’re tired of waking up feeling like you haven’t even been to bed, then a new alarm clock that reads your brain waves to pinpoint the best time to wake you up – so that (in theory, at least) you rise feeling fresh and raring to go – could be for you.
Sometimes science has a strange way of proving what every body else has known all along, so here it is : Apparently “Men and Women are different”. Not only that but their brains are wired differently!
When the red, red robin comes bob-bob-bobbin’ along, it’s not bobbing out of joie de vivre. The robin probably has one thing on its mind – food ! So how DO birds know where to peck for worms ?
