Nature is so smart, that took care of evolutionary progress - it has long been known that the stagnation in the flora and fauna to anything good does not. More talented breeder and geneticist engineer than nature, is not found. Due to the evolution of species of living organisms are constantly changing: there are new, more adapted species, and the old ones die out. All true ... Or rather, it was - in fact due to human activity has accelerated the natural extinction of 100, if not a thousand times. Already extinct many species of animals and plants - and the process continues. Let's try to remember how animals look, which is no longer on this planet - remained only their photos.

Thylacine - the marsupial Tasmanian tiger
This animal is one of the most mysterious and even legendary. Due to the fact that the thylacine loves fresh meat (who does not like him from predators?) Who came to Tasmania settlers began to ruthlessly destroy it.
Tasmanian tiger looked like a big dog with a long tail and stripes on the back. The length of the thylacine reached 180 centimeters - from nose to tail. Animals have always avoided contact with people, and behaved not like its namesake, a real tiger. It is known that animals caught thylacine often surrendered without a fight, and many of them died suddenly - probably because of the suffering shock. The thylacine was chasing the victim until she is exhausted, he falls to the ground.
The last thylacine died in Hobart Zoo in Tasmania, September 7, 1936. Over a hundred years Thylacines were literally destroyed by settlers saving his sheep.

Zebra Quagga
These ungulates, close relatives of the usual zebra, well described by Mayne Reid in several of his works. However, he described the longer life Quagga, and the fact that "their skin is very tough and suitable for the production of durable bags, but the meat is usually thrown away." Here we see the consumer attitude to the nature of the people of that time (since then the situation has deteriorated further in spite of any "green") - then one could not hesitate to kill an animal just because he needed his skin.
In general, the Quagga killed and killed until the last of them died a natural death on Aug. 12, 1883 in a zoo in Amsterdam, Netherlands.

Passenger pigeon
The history of these extinct birds at the moment, is very revealing. 200 years ago it was one of the most common birds in North America. Many of the literary sources of the time convey information about billions of wandering pigeons that could for a few minutes to overshadow the sun with their bodies - they were so numerous.
How could it happen that these pigeons were destroyed? It's very simple - their meat is quite tasty as well as the number of pigeons almost defied calculus, they became massively to hunt - it's cheap and tasty food for poor people and slaves. So all of them were destroyed, and the last passenger pigeon, Martha, died on the first of September, 1914 in Cincinnati, Ohio. Just a hundred years of extremely abundant species was destroyed.

Baijiu - Chinese river dolphin
It seems that the Chinese river dolphin baijiu inhabiting the best times in the waters of the Yangtze River, became extinct. International expedition sent in search of the mammal in 2006, returned with nothing after a month of searching.
It is well known that in the 1980s lived in the Yangtze River about 400 individuals of this species. In 1997, scientists targeted search after, able to watch 13 times the representatives of this species - plus there is evidence of the fishermen, who claim to have seen a dolphin in 2004.
"We must accept the fact that baijiu died out and we lost this species, - said one of the leaders of the expedition in August Pfluger (August Pfluger). - This is a tragedy, a loss not only for China but also for the whole world. We are all incredibly sad ยป.
The reason for the extinction of the dolphin scientists call the increasing water pollution, and the constant congestion Yangtze cargo vessels.

Golden frog
This species of amphibians was only discovered in 1966, herpetologist Jay Savage. But the last entry regarding the observation of the golden frog, refers to 1989. These amphibians good feel around in the rain forests of Monteverde, Costa Rica.
The reason for the extinction of a frog again became a man - this time indirectly. Directly nobody hunted and destroyed the golden frog - scientists believe that this species became extinct due to global warming, unable to endure high temperature. Golden frog could exist only in a very narrow range of temperatures, and as soon as the temperature began to rise, this species became extinct.
P.S. The header shows the drawing of the dodo bird, the latter a copy of which was lost in 1681. This, of course, not a photo and drawing.
