Alberto switched the computer on and soon the screepolkadot price youtuben showed C: at the top. He wrote "Laila," explaining that this was an advanced conversation program.

"Yes, please."litecoin naar bitcoin"The Communists disdain to conceal their views and aims. They openly declare that their ends can be attained only by the forcible overthrow of all existing social conditions. Let the ruling classes tremble at a Communist revolution. The proletarians have nothing to lose but their chains. They have a world to win. Workingmen of all countries, unite!"

"If conditions were as bad as you say, I think I would have signed that Manifesto. But conditions are surely a lot different today?""In Norway they are, but they aren't everywhere. Many people still live under inhuman conditions while they continue to produce commodities that make capitalists richer and richer. Marx called this exploitation.""Could you explain that word, please?""If a worker produces a commodity, this commodity has a certain exchange-value.""Yes."

"If you now deduct the workers' wages and the other production costs from the exchange-value, there will always be a certain sum left over. This sum was what Marx called profit. In other words, the capitalist pockets a value that was actually created by the worker. That is what is meant by exploitation.""I see.""Darwin's observations of bird life on the Galapagos were even more striking. The Galapagos finches were clearly varied from island to island, especially as regards the shape of the beak. Darwin demonstrated that these variations were closely linked to the way the finches found their food on the different islands. The ground finches with steeply profiled beaks lived on pine cone seeds, the little warbler finches lived on insects, and the tree finches lived on termites extracted from bark and branches ... Each and every one of the species had a beak that was perfectly adapted to its own food intake. Could all these finches be descended from one and the same species? And had the finches adapted to their surroundings on the different islands over the ages in such a way that new species of finches evolved?"

"That was the conclusion he came to, wasn't it?""Yes. Maybe that was where Darwin became a 'Darwinist'--on the Galapagos Islands. He also observed that the fauna there bore a strong resemblance to many of the species he had seen in South America. Had God once and for all really created all these animals slightly different from each other--or had an evolution taken place? Increasingly, he began to doubt that all species were immutable. But he still had no viable explanation as to how such an evolution had occurred. But there was one more factor to indicate that all the animals on earth might be related.""And what was that?""The development of the embryo in mammals. If you compare the embryos of dogs, bats, rabbits, and humans at an early stage, they look so alike that it is hard to tell the difference. You cannot distinguish a human embryo from a rabbit embryo until a very late stage. Shouldn't this indicate that we are distant relatives?"

"But he had still no explanation of how evolution happened?""He pondered constantly on [yell's theory of the minute changes that could have great effect over a long period of time. But he could find no explanation that would apply as a general principle. He was familiar with the theory of the French zoologist Lamarck, who had shown that the different species had developed the characteristics they needed. Giraffes, for example, had developed long necks because for generations they had reached up for leaves in the trees. Lamarck believed that the characteristics each individual acquires through his own efforts are passed on to the next generation. But this theory of the heredity of 'acquired characteristics' was rejected by Darwin because Lamarck had no proof of his bold claims. However, Darwin was beginning to pursue another, much more obvious line of thought. You could almost say that the actual mechanism behind the evolution of species was right in front of his very nose."

"So what was it?""I would rather you worked the mechanism out for yourself. So I ask: If you had three cows, but only enough fodder to keep two of them alive, what would you do?""I suppose I'd have to slaughter one of them.""All right... which one would you slaughter?"

"I suppose I'd slaughter the one that gave the least milk.""Would you?""Yes, that's logical, isn't it?""That is exactly what mankind had done for thousands of years. But we haven't finished with your two cows yet. Suppose you wanted one of them to calve. Which one would you choose?"

"The one that was the best milker. Then its calf would probably be a good milker too.""You prefer good milkers to bad, then. Now there's one more question. If you were a hunter and you had two gundogs, but had to give up one of them, which one would you keep?"

"The one that's best at finding the kind of game I shoot, obviously.""Quite so, you would favor the better gundog. That's exactly how people have bred domestic animals for more than ten thousand years, Sophie. Hens did not always lay five eggs a week, sheep did not always yield as much wool, and horses were not always as strong and swift as they are now. Breeders have made an artificial selection. The same applies to the vegetable kingdom. You don't plant bad potatoes if there are good seed potatoes available, and you don't waste time cutting wheat that yields no grain. Darwin pointed out that no cows, no stalks of wheat, no dogs, and no finches are completely alike. Nature produces an enormous breadth of variation. Even within the same species, no two individuals are exactly alike. You probably experienced that for yourself when you drank the blue liquid."

"I'll say.""So now Darwin had to ask himself: could a similar mechanism be at work in nature too? Is it possible that nature makes a 'natural selection' as to which individuals are to survive? And could such a selection over a very long period of time create new species of flora and fauna?""I would guess the answer is yes.""Darwin could still not quite imagine how such a natural selection could take place. But in October 1838, exactly two years after his return on the Beagle, he chanced to come across a little book by the specialist in population studies, Thomas Malthus. The book was called An Essay on the Principle of Population. Malthus got the idea for this essay from Benjamin Franklin, the American who in-vented the lightning conductor among other things. Franklin had made the point that if there were no limiting factors in nature, one single species of plant or animal would spread over the entire globe. But because there are many species, they keep each other in balance.""I can see that.""Malthus developed this idea and applied it to the world's population. He believed that mankind's ability to procreate is so great that there are always more children born than can survive. Since the production of food can never keep pace with the increase in population, he believed that huge numbers were destined to succumb in the struggle for existence. Those who survived to grow up-- and perpetuate the race--would therefore be those who came out best in the struggle for survival."

"That sounds logical.""But this was actually the universal mechanism that Darwin had been searching for. Here was the explanation of how evolution happens. It was due to natural selection in the struggle for life, in which those that were best adapted to their surroundings would survive and perpetuate the race. This was the second theory which he proposed in The Origin of Species. He wrote: The elephant is reck-oned the slowest breeder of all known animals,' but if it had six young and survived to a hundred, 'after a period of from 740 to 750 years there would be nearly nineteen million elephants alive, descended from the first pair.' "

"Not to mention all the thousands of cods' eggs from a single cod.""Darwin further proposed that the struggle for survival is frequently hardest among species that resemble each other the most. They have to fight for the same food. There, the slightest advantage--that is to say, the infinitesimal variation--truly comes into its own. The more bitter the struggle for survival, the quicker will be the evolution of new species, so that only the very best adapted will survive and the others will die out."

"The less food there is and the bigger the brood, the quicker evolution happens?""Yes, but it's not only a question of food. It can be just as vital to avoid being eaten by other animals. For example, it can be a matter of survival to have a protective camouflage, the ability to run swiftly, to recognize hostile animals, or, if the worst comes to the worst, to have a repellent taste. A poison that can kill predators is quite useful too. That's why so many cacti are poisonous, Sophie. Practically nothing else can grow in the desert, so this plant is especially vulnerable to plant-eating animals."

"Most cacti are prickly as well.""The ability to reproduce is also of fundamental importance, obviously. Darwin studied the ingenuity of plant pollination in great detail. Flowers glow in glorious hues and exude delirious scents to attract the insects which are instrumental in pollination. To perpetuate their kind, birds trill their melodious tones. A placid or melancholy bull with no interest in cows will have no interest for genealogy either, since with characteristics like these, its line will die out at once. The bull's sole purpose in life is to grow to sexual maturity and reproduce in order to propagate the race. It is rather like a relay race. Those that for one reason or another are unable to pass on their genes are continually discarded, and in that way the race is continually refined. Resistance to disease is one of the most important characteristics progressively accumulated and preserved in the variants that survive.""So everything gets better and better?""The result of this continual selection is that the ones best adapted to a particular environment--or a particular ecological niche--will in the long term perpetuate the race in that environment. But what is an advantage in one environment is not necessarily an advantage in another. For some of the Galapagos finches, the ability to fly was vital. But being good at flying is not so necessary if food is dug from the ground and there are no predators. The reason why so many different animal species have arisen over the ages is precisely because of these many niches in the natural environment."

"But even so, there is only one human race.""That's because man has a unique ability to adapt to different conditions of life. One of the things that amazed Darwin most was the way the Indians in Tierra del Fuego managed to live under such terrible climatic conditions. But that doesn't mean that all human beings are alike. Those who live near the equator have darker skins than people in the more northerly climes because their dark skin protects them from the sun. White people who expose themselves to the sun for long periods are more prone to skin cancer."

"Is it a similar advantage to have white skin if you live in northern countries?""Yes, otherwise everyone on earth would be dark-skinned. But white skin more easily forms sun vitamins, and that can be vital in areas with very little sun. Nowa-days that is not so important because we can make sure we have enough sun vitamins in our diet. But nothing in nature is random. Everything is due to infinitesimal changes that have taken effect over countless generations."

"Actually, it's quite fantastic to imagine.""It is indeed. So far, then, we can sum up Darwin's theory of evolution in a few sentences."

"Go ahead!""We can say that the 'raw material' behind the evolution of life on earth was the continual variation of individuals within the same species, plus the large number of progeny, which meant that only a fraction of them survived, the actual 'mechanism,' or driving force, behind evolution was thus the natural selection in the struggle for survival. This selection ensured that the strongest, or the 'fittest,' survived.""It seems as logical as a math sum. How was The Origin of Species received?""It was the cause of bitter controversies. The Church protested vehemently and the scientific world was sharply divided. That was not really so surprising. Darwin had, after all, distanced God a good way from the act of creation, although there were admittedly some who claimed it was surely greater to have created something with its own innate evolutionary potential than simply to create a fixed entity."

Suddenly Sophie jumped up from her chair."Look out there!" she cried.

She pointed out of the window. Down by the lake a man and a woman were walking hand in hand. They were completely naked."That's Adam and Eve," said Alberto. "They were gradually forced to throw in their lot with Little Red Rid-inghood and Alice in Wonderland. That's why they have turned up here."

Sophie went to the window to watch them, but they soon disappeared among the trees."Because Darwin believed that mankind was descended from animals?"
