Some people get grey (or white) hairs in their twenties, and others still have dark hair well into their seventies and eighties. The process of greying can occur gradually over many years as individual hair follicles stop producing colour, or it can happen within a matter of months or a few years. How long depends a lot on genetics.
In a Nutshell – Researchers say it is in the genes.
It’s the same reason some people are brown-eyed and some are blue-eyed. The Human Genome Project tends to support the theory that a single gene is responsible for handedness
There are many people who often claim to have an arthritic joint with the power to tell the future, at least meteorologically. The idea that certain painful health conditions are affected by the weather is an ancient claim, dating back to at least Hippocrates in the 4th century B.C and no even doubt earlier. But can this phenomenon be explained?
When an animal looks in a mirror, does it realise that it is looking at itself? – this is really a question of self-awareness. So if any animals, apart from ourselves, do actually know this we then have to ask – Which, if any, animals successfully make this connection?
How Can Flies Fly at Speed into a Pane of Glass and Seemingly Remain Uninjured ?
The answer lies in a basic physics equation – one we would all have learned at school – and in the fact that the anatomy of a fly is rather springy.
Grass stems and similar green leafy bits of plants make up the major part of the diet of many common animals, including cows, sheep, kangaroos and horses. If they can eat it, so why can’t we?
Did you know that your sense of smell and taste are connected? Also, as you get older, these senses can change ?
The problem with dinosaurs is that they lived a very long time ago- between 250 million and 65 million years ago – But is possible to tell what the lifespan of a Dinosaur might have been ?
From the fossil evidence, it’s clear that, species by species, individual by individual, dinosaurs were more massive than any other group of animals that has ever lived on land. It’s as if today’s laws of physics didn’t apply back then allowing them to grow to such a gigantic size. So what could possibly explain this ?
Reality is sometimes stranger than we’d ever credit. Believe it or not but Scientists are actually saying that they can prove that Adam & Eve, that is a single set of ancestors, are parents to us all!
There is a deep-rooted idea in the Western world that fresh air and sunshine are good for us. Going back to medieval times, the spread of disease was often blamed on bad or malodorous air. The idea that fresh air could cure has been current right up until our recent history. Well, it looks as though all those medics of yesteryear may have been on to something after all.
Another one of those random questions that seem to come out of nowhere as it flits across our minds – Why Exactly are Eggs egg Shaped ?
Until recently, we knew nothing of the skin of dinosaurs. Depiction of their colour was left to the imagination of illustrators. In 2009, however, that all changed when remnants of skin and ‘proto-feathers’ , actually hairlike filaments—sometimes called dino fuzz, were found on some dinosaur remains in China.
