As a child I was fascinated by the dinosaurs immediately, I was simply electrified. I have them painted, studied and tried to understand her evolutionary failure. 180 million years the dinosaurs on earth haven't only survived, but almost blossomed. They have takes up every living space of the earth of the equator to the poles. They looked like as the big evolutionary winners of the nature, nevertheless, they failed very sudden. Was her true job as "Terraformer" expired?

The plant world is the quite first big Terraformer of the planet. Invention of the photosynthesis before one and a half milliard years brought also his first big climate disaster to the planet by Cyanobacteria (blue algae): now the air was "poisoned" with oxygen and for the living beings at that time pure poison. Then before 530 million years ended the "Cambrian Explosion", and the biggest species extinction of all times
destroyed 95% of all kinds. The huge widespread deaths left within a short time the seas tip over, and the calcium salary of sea water trebled. For surviving sea organisms a pure deadly problem. As usual, the evolution didn't remain inactive, the tough work of selection and adaptation brought out them the cellular mechanism of the "calcify". The sea organisms "learned" to harden the lime on her exterior surface.

The dinosaurs who dominated these planet one quarter of milliard years were the second quite excellent Terraformer. Not only because they formed the scenery with her weight by steamroll, but because with her dietary habits and fertilizer capacities they formed whole ecosystems. Just if we take seriously the "Gaia" hypothesis that the earth is a living organism, we must reconsider the narrow frame of our anthropocentric thinking. Evolution has on her long way from the protozoon to the intelligence
endlessly many technologies fictitious. Why, here must ask heretical, "were allowed" the blue algae produce the nervous poison oxygen, the

dinosaurs him whole planet transform, but people wear kindly without tracks to live on this planet? So in an ecological zero niche, or how today is in habit to say politically "with lasting effect"? The dinosaurs got indisputable in an evolutionary dead end as before approx. 65 million years a global disaster of extraterrestrial origin in the form of an asteroid hit the peninsula Yucatan and the primary food net completely broke down. Simulations feature, the glowing lumps of the impact all over the world came again down and secondary impacts and fires released. The following global impact winter or nuclear winter destroyed the food niches for big living beings for a long time. During the global winter only few little plants grew very much, therefore, bigger herbivores
couldn't survive, in so far as the food basis was also taken away of the big carnivores.
Such a mismatching is able only with a sudden and dramatic change of the
environmental conditions stamp. A world, striking from worldwide blazes and a nuclear winter (or poisoning the ecological sphere by the Indian super volcano), is a really dramatic change. Practically every animal who was bigger than approx. 1 meter doesn't have survives the crossing of the chalk time to the geologic period paleogene. But the dinosaurs didn't become extinct completely, some small kinds have survives and today they live on earth as "birds".

The beginning of the end of the dinosaurs are founds in the evolutionary strategy of the egg laying, while mammals bear her younger generation living. Reptiles lay eggs. In the case of the dinosaurs this was in the impact winter an uneconomic strategy. Dinosaur eggs could not become big any, because they necessary thick eggshell would have hindered the oxygen exchange. Though dinosaur eggs owned inside an air bubble as an reservoir as well as today chicken eggs, but this didn't reach for supply only and
also didn't need. The eggshell itself was air-permeable, in an eggshell of a normal chicken egg are approx. 10,000 pores, about that a constant air exchange takes place. Thus oxygen comes to the egg and therefore also in the so-called air bubble.

Besides, there was an extreme dimensions discrepancy between adult animals and born animals what could be compensated again only by a huge absorption of nutrients which didn't exist any more. The strategy of the mammals was more successful there, they had it under the given catastrophic circumstances though also easily, however, but they did succeed to survive themselves of the changes by her low size of adapt, ate small plants and searched insects and invertebrate. Also mammals gave an energy bonus for a first "developing push" to the younger generation by means of mother's
milk by which they could get well prepares in the food niches. That without this event, apparently for an extreme "settlement" of the biodiversity led, presumably the mammals and the person could never have become so dominant and that the latter (the person) quite obviously is heard to the momentary evolutionary "winners". Seldom a complicated kind has dominated the global ecosystem so and develops those adaptation abilities. When the dinosaurs became extinct, the way also became freely
for the birds who are the direct successors of certain predatory dinosaurs. In geologically short time her kind number exploded which it makes birds to one of the most varied vertebrate groups on the earth. This is of the results of one the most extensive genome analysis up to now, witch the biologists have made.

Sometime I came to the strange question, whether also a dinosaur had a soul, because I was aware, that the human skin is a cover for our soul. The skin is our biggest organ, we experience ours whole feeling world in the quiet statements of the skin. If we are full love, a pleasant sensation fulfills us from the inside. Just wrapped in clothes we fell
warmth and comfort. With only negative feelings like envy, hatred or in quarrelsome atmosphere we feel cold, also physically. The mental feeling can bring our skin to the sweating or we get creeps. A thick fur have indicated to be almost uninterested. Everybody our mental sensations become visible about our skin and indeed stands with all organs in lively connection and interrelation. Moreover, it's a mirror of organic condition which disturb our internal harmony. She has a important activity as an
excretory organ, she serves the oxygen and nitrogen exchange and also fulfills the job of a thermal regulator and climate guard if we freeze or sweat. She breathes.

But this - and the reason for the gigantism of the dinosaurs - is worth to let circle the thoughts for an own chapter...
