Brain Evolution and Charles Darwin's principles

According to Charles Darwin's theory of evolution, some species carry on to survive and prevail in their environment, while other species tend to disappear because they are not strong enough. The selective process decides which species lives and which will become extinct, depending on their resistance.

This thought is standard by many citizen until today and they refuse to understand that Darwin was wrong.

Darwins

He was right when he discovered that the human being is an animal, but the evolution of the species doesn't occur based on the resistance of each species, as many biologists after Darwin proved to the world with their research.

Brain Evolution and Charles Darwin's principles

They accomplished that if the organism didn't have the basis to evolve until confident point, it would never go further. There is a program that allows each organism to know how to behave in its environment and how to solve its survival problems, together with how to find food and be protected from enemies. There is also an evolutionary program in each organism's cognitive mechanism.

A monkey will never be as thoughprovoking as a human being, no matter how many years it may live, because it doesn't have a allowable brain. It was not programmed to be as thoughprovoking as man. So, there is no natural selection: there are only many programs for each species. These programs define the animals' behaviour, the route of their lives and evolution. The same happens in case of human beings.

Darwin's conclusions by observing the selective process were based on the knowledge of his time. He couldn't suppose that there are some programs behind the selective process that prepares each species to resist natural selection, which means that this selection doesn't happen by chance.

When we try to understand the formation of the human brain and the appearance of the conscience, we perceive that this is a formation that took an incredibly long time. It cannot be something that could have evolved in our planet, because our planet is too young and the components of the human brain and their functionalisms are too complex.

The formation of the first brain and conscience occurred by chance at a time so distant that we cannot hypothesize it. It didn't take place on our own planet, in the same way that the formula for the formation of the first live cell didn't appear by chance in our planet because the planet's age (about 4.6 billion years old) is not enough to allow all the necessary combinations required by probability for the formation of the first live cell, since the permutations and combinations for this event would have been too many and they would take more time than the planet's age itself.

Therefore, we can stop that the human being didn't appear on Earth by chance. The human brain and the formula for the appearance of the animal life are ancient and could not have been advanced in our young planet, but all the animals, together with man, have behavioral programs in the mechanism straight through which they derive knowledge. These programs permit their excellent functionalism and survival in a hostile environment. Programs that might have being prepared by a classic brain for sure, since they could not have appeared by chance.

Thus, the human being inherits an ancient brain that can think and feel and is aware of its existence, but one has to pass straight through the same evolutionary process straight through which all animals pass in this planet, because probably, one has to be tamed like them...

Charles Darwin's Origin of Species

In 1859, Charles Darwin, an English naturalist, published one of the most prominent books in the history of science. This book is today popularly referred to as "On the Origin of Species", although the full title was in fact  "On the Origin of Species by Means of Natural Selection, or The Preservation of Favoured Races in the Struggle for Life".

The contents book explained, at some indispensable length, ideas that Charles Darwin had been developing for about a quarter of a century, since his five year trip (1831 to 1836) nearby the world on the Royal Navy ship, Hms Beagle. The core of these ideas was the idea of evolution by natural selection.

Darwins

Many habitancy today misunderstand what Darwin's gift to science was:

Charles Darwin's Origin of Species

* Some habitancy think Darwin's principles concerns the origin of life ("abiogenesis"). Darwin did not  easily deal with this matter (although he did make some speculations in inexpressive letters and maybe other writings) - his work is easily involved with how life changes over time, and new species emerge ("evolution").

* Other habitancy think Darwin was the first man to recommend the idea of evolution. This is not correct either. The idea of evolution - namely successive generations of organisms change over time - can be traced back to the antique Greeks. In more contemporary times, natural philosophers of the 18th and early 19th centuries (including Charles Darwin's own grandfather, Erasmus Darwin), were widely discussing evolutionary theories.  What Darwin's gift was however, was to recommend a mechanism, namely natural selection, by which organisms can evolve adaptations to their environment, and by which new species can emerge (and today, natural selection is recognized by scientists as the driving force behind adaptive evolutionary change).
