Natural selection

Natural selection is one of the basic mechanisms of evolution with mutation, migration, genetic drift.

The wonderful idea of ​​the evolution of Darwin by natural selection is relatively simple, but it tends to be misunderstood. Imagine the number of beetles to understand how it works.

Because the environment can not support unlimited population growth, everyone can not fully understand its possibilities. In this example, the beetle is often eaten by birds and it is more likely to breed than a beetle.

More favorable properties, brown coloring make beetle more progeny, becoming more common in the crowd. If this process continues, eventually all of the population will turn brown

If you have mutations, discriminatory breeding and inheritance, you will evolve through natural selection as a result. It's very easy

Natural selection encourages the evolution of these creatures and ultimately creates you and my natural choice. Strangely, we can condemn the natural choices that create the current state of pain and ignorance. This is an important point as it suggests that your pain is not really "completely responsible". Contrary to the guilt that our religious and civic authorities are about to impose on us - our sufferings are not due to our moral mistakes altogether. It is like a byproduct of our biological evolution. More importantly, it is the main driving force for human evolution. Somehow, we began to rely on pain to survive, which causes some problems for us today.

Natural selection is easy to understand, but it is often misunderstood. Natural selection is not synonymous with evolution. Evolution refers to any genetic change in a group, natural selection identifies a specific way of this change. Natural selection is the most important element in evolutionary change, just because it adapts life to its environment. In addition to natural selection, other potential evolutionary mechanisms include gene flow, meiosis and genetic drift

Natural selection As Charles Darwin asserts, natural selection is due to adaptive genetic differences and is the third potential cause of evolution. Even though it is not the only reason, natural selection is now considered the main reason for adaptive adaptive evolution. For example, the speed of the gazelle and the cheetahs following it are all natural choices. Immigration and immigration. Immigrants and immigrants can bring out or eliminate specific genes. Human worldwide movement increases the importance of these forces. It is not only in the population but also in many other species traveling with people like African Bees. The so-called killerby from Africa is currently changing the genetic frequency of the bee population in the south of the United States.
