Do identical twins have the same fingerprints?

And how are our fingerprints determined? Read on to know the answers

Identical twins form when a single fertilized egg splits into two. Therefore they have the same genetic make-up and their DNA pattern is indistinguishable. Their fingerprints have similar patterns of whorls and ridges, but there are slight differences.

This is because genetics is not the sole determining factor in the development of fingerprints. Fingerprints are determined by the interaction of an individual's genes with the environment in the womb and factors such as nutrition, position in the womb and the growth rate of the fingers. No two persons can have the same fingerprints.

Where can you find the gorilla?

The gorilla lives in the dense forests of equatorial Africa. It is the largest and most powerful of the ape family. The gorilla is extremely strong but it is a unduly disturbed. But other animals are very much afraid of it: few of them will dare to attack a gorilla because they know they would have the worse of the encounter.

A full-grown gorilla stands nearly 2 metres tall, with a massive body and very muscular arms and legs, and can weigh over 200 kilograms. Its jaws jut out and it has a broad, flattened nose and huge beetling eyebrows.

There are two main kinds of gorilla: the lowland gorilla that lives in the rain forests of western Africa, has a dark grey coat; the mountain gorilla which lives in the eastern regions of Zaire-Uganda borderland at altitudes of more than 3,000 metres, has black fur, Little is known about the ways of these big apes. This is because gorillas are very shy animals and also because they were first found only during the last century.

Gorillas usually live in groups which include both young and old. They build rough dwellings in trees a few metres above the ground. These dwellings look like platforms made of branches and twigs.

Gorillas do not spend all their lives in the trees. During the day they wander about on the ground looking for food. They feed on leaves, roots and fruit which the forest has in plenty. Gorillas walk in a crouching position, but every so often they stand up straight on their long hind legs.

Where the wild peacocks are found?

Wild peacocks live together in large flocks in the forests of central Africa, India, Sri Lanka and southern Asia, They search for seeds to eat during the day, and at nightfall they fly up the trees where they perch and sleep.

Every peacock has several wives known as peahens. The female birds build their nests on the ground and lay from four to six whitish, sometimes spotted eggs. During the mating season the male utters a harsh raucous cry.

Peacocks were first brought to Europe in the days of Alexander the Great. At one time they used to be kept on many farms, but today they are usually found in zoos or public parks.

Peacocks are extremely beautiful birds with their brightly coloured plumage. The male bird makes a magnificent display when it opens up it opens up its huge fan-like tail to preen itself. The female is more dully coloured and does not have the large ornamental feathers.

How does the desert rat live?

Desert rats can be seen during moonlit nights scampering and hopping about the desert sands. These animals, also known as jerboas, come out of their hiding places only after dark in search of food.

But they do not seem to be looking for food as they jump about. Their bodies are about 20 centimeters long and the tail, which ends in a tuft, is some 25 centimeters. The front limbs are extremely short while the hind pair are about six times as long. They are very funny to watch as they hop about on their long hind legs that look like those of kangaroos.

Desert rats live in burrows which they dig with their nails and teeth. They are shy animals and this, together with their agility, makes them difficult to catch. They live quite well in captivity, however, and are extremely clean in their habits. They have a sand coloured coat, as most desert dwelling animals have.

Where you can find forests full of beech trees?

In parts of western Asia and all Europe as far as southern England, beech trees can be found growing in gardens and large avenues.

There are many different kinds of beech including the dark-leaved copper beech and the weeping beech, often to be seen in parks.

The best beeches are found in chalky soil some of them reaching from about 30 to 45 metres high. Many were first planted in the eighteenth century on huge estates.

The timber of the beech is heavy and hard and is extremely useful as firewood. It also has many other uses and is especially noted for making fine furniture and all sorts of different wooden articles.

When the lynx was seen again in Europe?

The lynx is a large, wild, feline animal found in many parts of central Europe. It has unusually large paws, a mottled tawny to cream coat and a black-tipped tail.

The lynx lived in the Alps until half a century ago: the last time this creature is known to have been captured was at the beginning of this century, near Chieri in Piedmont. The animal has not been heard of since.

It is more likely to be the clearance of all trees from the mountains which have caused its disappearance than the fact that it has been hunted down. A deer which had been completely ravaged as if by a lynx, was recently found in a Swiss forest, where there were also impressions in the fresh snow which scientists have identified as tracks typical of his feline creature.

The lynx is now being bred in zoos and then released into the wild to build up its numbers. It usually lives in dense forests where it can find it favorite prey, the roe-buck and the stag.
