"Evolution" do you belive on it?

Most people have heard about it, but not to believe that it is possible. But most people who see it as wrong, they do not understand. I will try to clarify inaccuracies in the theory of modern development. This means that the development is the process in which the animals in the course of time. However, this figure in the history a little too much. Most people who do not believe in development do not fully understand. These people believe that the theory says that humans came from apes. That is not true. These people believe that if an animal develops, there is no requirement for the animal alive. That is not true, not more.
The evolutionary theory describes how easy life is changing with time. This is not a few weeks, years or even centuries. In most cases it takes millions of years to be completed. The entire process of development begins with a mutation. Such a mutation is an animal that differs from the norm. For example, an albino garter snake is a mutation. A lucistic alligator is a mutation. Everything is not normal in a living creature, the DNA is a mutation. It is obvious that certain changes would benefit more than others. It is there that "Survival of the Fittest" scene. For example, a bill on nectar of feeding the birds is an advantage because they collect the birds much easier of nectar. Other changes, like an albino snake in a dark green jungle, in fact malicious. It is obvious that this snake is not in a position to camouflage against predators, as he is still young, so that a simple meal. The snake never survives in the age to reproduce. The animals, better suited to their environment survive, so are not repeated.
There are some times when the changes in the environment, such as the Ice Age. Over time, most of the world's freezing cold and snow. The animals with a gene to have hair usually die by the heat exhaustion in the previous era. But now the hair is in a position to keep the heat in their bodies enabling them to survive better that the non-hair. The no hair began to disappear because they are the ones that hair. The type is straight. As the climate changes that are suitable in the new environment survive and reproduce, those who are not die.
Sometimes the animals are kept separate from other animals to their nature, such as the Galapagos Islands. These animals have a private gene pool away from the other animals, and they also live in another country. This means that two samples of a species may be different. A sample for bird May develop a draft law for the harvest easier, while the sample developed a short bill for more control over the draft law, and the final sample of bird species remain unchanged in May. Finally, through these and other changes, the two birds ultimately can be so different that it no longer. Another new species is now available.
Many people think that there is no evidence to support the development. On the contrary, there is much more evidence that the other theories on how life came to be. If you have two cats taxonomic, they are the same species. You may respond to multiply and produce fertile young people. This means that all types of cat are the same, Felis domesticus. As you all are? The selective reproduction is the key. The reproduction is selective before forced to a development of species. If people have the first Siamese cat, they have decided to do more. For their breeding with another cat, it is possible to have this change. Further evidence of the existence of the development of appropriate structures, these structures are of the same thing, but other tasks. If the structure of the skeleton of a whale-flipper, he has the same bones of the hands of the people. There are many other situations like this.
Finally, the development is an issue, quite simply, if you from time to understand. To get a kind of all needs of a mutation is beneficial and the death of the original version of the case. As a kind of isolation from the development of population, it forms a new species. Since the original version is still alive, here has not changed, but a new way.

How did life begin?

What are the origins of life? How things from the non-life to live? From what is not reproduce, something that could? A person who is not as comprehensive is the theme paleontologist Andrew Knoll, professor of biology at Harvard University and author of Life on a small planet: The first three billion years of life. In this extensive interview, Knoll explains that among other things, ideas, why the higher organisms like us, are the cherry on the cake of life, how things are alive and our planet are closely linked, and why is it so damn hard to understand how life began.

People have tried, a general, universal definition of life. They are speculative, because we do not know the whole lives of others, which we ourselves. But a definition that I have a little, as I said, life is a system that is capable of Darwinsche evolution. What they need on a system developed in response to an darwinistischen? First, you must be able to reproduce and make more, it is our local definition. In addition, you need a change, that all the new generation is not identical, the previous generation and all his brothers and sisters. And when you change, and natural selection can select from a difference of birth or death, some of the variations which work best. May show that a fairly general definition of life that we could find.

A Brief History of Life

For most of us, the pyramids symbolize the past. Finally, they are more than 4,500 years. But for the geologists and palaeontologists, they may very well have been designed to be yesterday. This is because these biographers importance of treatment in increments of millions and even billions of years in their struggle for the reconstruction of our planet's life history, which is so great that the 4500 years old, are increasingly focused on one million times more To the Earth in its infancy 4.5 billion years. From a different angle, if we should measure our planet as a unique age than 24 hours per day, the first human civilizations seems to be less than one second before midnight.

The geological time scale, by the scientists in the mid-19th Century and has been on an international level, which breaks in the eternity of the world's history in units easier to administer than years. The scope of functions such as a calendar-solid, divided into the history of life in the times, times, periods and on the basis of evidence fossils. In this role, the study of the history of life on Earth as we know it today, once the youngest of the bacteria for the first modern man. To implement the interactive, click on the image left.

"Life is really part of the fabric of a planet like the Earth."

Life is also supported by the planet itself. It is as all the nutrients in the oceans and begin to spread in the biology, at the beginning, they are caught in the rocks, and they are the erosion of rocks, between the oceans, and in a recycling complex ensures that are still made of carbon and nitrogen and phosphorus for each new generation of organisms.

The most interesting idea that not only the life presents itself as a product of the global process, but in the fullness of time, at least on this planet, life is as a result of global processes that are important in their own right. We are sitting here today oxygen to breathe, a rich mixture from the air. We could not be here without the oxygen, but oxygen was not at the top of the soil, and it was only because of this activity by photosynthetic organisms. Also, in a word, life is really part of the fabric of a planet like the Earth.

------Planet Earth has full of mystery that must be reviled. So until next time as you revisit this site you’ll know about all the mysteries in all of the aspect and origins about the universe and much more… Enjoy your reading as you learn because the powerful tool in knowledge is reading… Have a nice day!!!

"Water of life" can we live without it?

Could life as we know it does not have a beginning, without water? Some scientists have suggested that global, that in some very cold liquid ammonia planetary body can instead of water to incubate life. But even though the community non-aqueous liquid ammonia seems several other cases against them as a way of life. His route fluid is low, only about 30 degrees. Even if it freezes, it flows, and we know what this.

Some have suggested that the oceans of methane and other hydrocarbons in the places like the moon of Saturn, Titan could also serve the goal. But here we are talking about the temperatures so low that the chemical reactions, as we know it could be at a pace Frostig. "At least 150 degrees," says Bada, "most believe that in view of the importance of the origin of life would probably not take place over the age of the solar system." Moreover, the compounds such as amino acids and the DNA is not soluble in those other liquids. "It would be just Globs gunk," said Bada.

For these and other, the water is still the Holy Grail for the scientists of the planet, which, based on what they know now that it is probable that liquid water is essential in food, land and extra. Explains Neil de Grasse Tyson, an astrophysicist and director of the Hayden Planetarium at the American Museum of Natural History, "because life on earth is also dependent on the water, and given the fact that the water is so widespread the universe, we do not believe that we are on a branch-to-say that life should be with water. "

Just as a blue sky requires blue light to dispel further than any other colors of visible light spectrum, of course, why the sky is blue. Well, the answer is simple anyway.

What is the recipe for life?

The recipe for life is not so complicated. There are a limited number of elements in your body. Most of your mass of carbon, oxygen, hydrogen, sulphur dioxide, and some nitrogen and phosphorus. There are a few dozen other elements that are there traces, but for a first approach, you are only a bag of carbon, oxygen and hydrogen.
Now, it became apparent that the atmosphere is a bag of carbon, oxygen and hydrogen as well, and it was not live. Thus, the real problem here is, as you carbon dioxide in the atmosphere (or the beginning of methane in the atmosphere) and water vapour and other sources of hydrogen, how do you take the simple basis of inorganic substances and makes them the building blocks of life?
It was a famous experiment by Stanley Miller when he was a student at the University of Chicago in the early 1950. Miller, in substance, methane or natural gas, ammonia, hydrogen, gas, steam and water in a bowl. This was not a random mix, then, it has experienced, it was at least an idea of what the atmosphere of origin would have looked like.
Then he has a brilliant thing. It simplifies, an electric charge by the mixture to simulate lightning go early by an atmosphere. After sitting for a few days, suddenly there was this brown goo reaction of all vessels. When he analyzed what happens in the ship, not only with the methane and ammonia, he had indeed amino acids, the building blocks of proteins. Indeed, he had just about in the same proportions, according to you, if you have an organic substance meteorites. While the chemistry of Miller was the discovery of this magnificent experience was not unlikely, certain chemicals, but a chemistry, the most prevalent throughout our solar system.

For the first eight to ten years of their life

For the first eight to ten years of their life, they live a life they were entirely before the hard truth of the world outside of their parents in general. However, once they turn eighteen and collegial studies, they are no longer from their parents in the culture of today see this transition in one of the measures in adulthood. The students are on the principle of collective responsibility completely clueless the many truths in the world. It is not as pleasant and entertaining, as they have taken it to May.

In most cases a decision from May student is on the whole basis of religion. For the first eight to ten years of their life, they were May participate in the church or another place of worship, whenever appropriate. They may be transmitted to such a place as their parents and continue to support this responsibility because it was perceived that they had to do something, or they were forced to go, as I was during my childhood.

Once they were in college that they develop their mind more and more into a state of a better understanding of the world May in order to be able to adapt and be able to live in society of today. Now they are in college or perhaps even before they come into question their religion, like almost everything the world has done at least once somewhere along their lives. Questions and pop in their heads, to ask why the world is as it is today.

-- If God is a sentence to know, Allmächtiger why, as we are on the issue of its existence and can not ensure that we think without him?

-- If there is only one God, why is it so that it is used by different sects in the way they worship the Lord May?

-- If God is love, which is currently limited to the concept of forgiveness without end, to institutions such as the demons, Apocalypses as the end of days, places and essential as hell?

-- If we were manufactured, in the image of God, why is a taboo for us to understand what God created us to be like him.

-- If God loves us so much, why is what we must try our obligation to live in a world fatal?

The other issues are a student in May is increasingly argued, as they have come to the question of religion more and more and see how it is not consistent. Even with the response of the practice as totally "faith" in today's society rules and logic of the World "faith" completely out that even the logic. It is commonly said that the logic should not be used to address issues like religion, because it is based on the conviction, something without any proof or makes sense.

I think that they are cruel practice with answers like "faith" as a basis and all their answers to a circular, if nothing in their basis, it was also shown true, but even removed and they use this false logic on a real answer.
