"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!!!
