All this is known also to demographers long ago, society gives a set of examples. In any case, many hotly challenge a salutary role of an appeal to unlimited reproduction of the population.

But why not to assume, what some other classification will appear more ? - if to consider their physiology - is closer than Kieta to rabbits, than to fishes. But so far as there was a task to catch a whale, you by all means will go there where fishes, but not rabbits live. So from the practical point of view it is more convenient to construct classification, maybe, by a dwelling area, having placed a whale with fishes, and bats with.

Thus, the word "of" really to three very differing types of the flying creations: to insects, actually birds and mice. (There was also the fourth: the flying pangolin the pterosaur, but it died out long ago, and authors of "the code" had no about is mute the slightest. )

Elders among the terrestrial flying beings - insects. The most primitive of them occupied with one of the first the land about 400 of years back. That pervonasekomy, most likely, were not able to fly, and about 100 million more years passed until evolution took care about ­.

Well, it is not deprived of sense. All live cannot breed continuously, so far to it not sufficient stocks of food and a safe environment. Both - truly happiness, it will easily confirm everyone who is deprived of the first or second.

It will seem to the modern reader strange (as, however, and reference of whales to "fishes"): bats and whales belong to group though elements of the first - the sky, and the seas never left. But it is necessary ­ to remember all that any classification - a of human mind. It we group types of animals in group of mammals, proceeding from proximity of their some signs - incubation of cubs, mammary glands and a diaphragm, indumentum and so forth. For us all this the life makes sense in the light of an evolutionary picture.

Microscopic forms of life arose at the ocean 3,5 billion years ago. Decent invertebrates teemed in sea depths about 600 million years ago, and the first fish known to science appeared later 100 million years. After that 300 million years passed - and there are plesiosauri, the truth which died out later 130 million years of an undivided hozyaynichanye in water open spaces.

And here during more than 100 million years spaces of the planet undividedly an insect. About 170 million years ago there were first pterosaurs and birds. Through one hundred millions years pterosaurs died out, and birds survived and as we know, succeeded. Bats were last "flying" having been born about 50 million years ago.

After creation of sea and heavenly creatures the Lord is accepted for final and, from a point a of the person, the most responsible part of work: settling of sushi. The scheme tested earlier is successfully applied and this time: all animals are created and from the very beginning divided into types. Vastly we will not repeat already told more than once: the science holds absolutely other () opinion.

Early samples of microlife included also "animal" cages incapable to support photosynthesis and subsisting at the expense of the. And only about 600 million years ago numerous organisms of the decent sizes - the living beings possessing internal structure what it is possible to judge on fossils.

The sorted verse also suggests an idea that the foresight from the very beginning defined some mammals for a role of a livestock. It, actually anything similar could not be: all animal species originally were wild: domestication of some represented labor-intensive process. And mankind ­ to domestication of wild animals not so long ago.

And today the ocean is full microorganisms, existence form for others a basis. more developed life forms. The huge part of this floating microlife - a plankton - from the green cages which are carrying out a photosynthesis just as their green analogs on the land. It is enough to tell that about 4/5 all on Earth falls to the share of sea vegetation.
