Natural selection is a key mechanism of evolution, the change in heritable traits of a population over time. Charles Darwin popularized the term "natural selection". He compared it with artificial selection, which is intentional, whereas natural selection is not.

Variation appears through gradual mutations in individual organisms when individual heredity follows species-specific information. Individuals with certain variants of the trait may survive and reproduce more than individuals with other, less successful, variants; therefore, the population evolves.

Natural selection acts on observable characteristics of an organism and more reproductive advantage may become more common. Over time, this process can result in populations that specialize for particular ecological niches and new ecological conditions. Natural selection is a key process in the evolution of all populations. The union of traditional Darwinian evolution theory and classical genetics form the modern synthesis.

It is now being asked whether the evolution of intelligence can be raised to include robots and whether they will come to ethical value choices. Or is there a definitive estimate on man's ethical choices, for example between good and bad. Development is scaring when talking about the artificial intelligence and its impact as a rival to the development of human evolution and ethics.

Today, the concept of evolution also covers the outer space where the same elements of development are found as on Earth. We know more and are aware of the transformation of the factors we have in our environment and therefore the world view have gained a cosmological dimension.

Multitasking means in everyday speech working with several tasks at the same time, and the ability to quickly switch between different tasks. It means the simultaneous execution of multiple tasks under the same operating system; the practice or capability of handling more than one task at the same time.

Many different media users believe they are good in multitasking, but the results do not prove it. The quantitative use of different sources does not necessarily prove the ability to process information analytically and prioritize things. Performing parallel tasks and observations is the result of experience and practice rather than a personal feature.

Exercise has been shown to improve and facilitate the performance of individual tasks in multitasking. The key is the ability to deal with new things, attention-control, short-term memory, time management and decision-making ability.

In multitasking there are risks, too. The pressure exerted by the tasks and the ongoing unfinished tasks are serious stressors in today's society. Stress is shifting more and more to the use of leisure media. The presence of social media and the maintenance of the debate set 7/24 are essential.

It is said that our brains are in alert state without a natural slow down and stop of multitasking. We try to do too many things at the same time, or alternatively we are not able to focus on one thing so that we can get to the finish line. Involved in social media (Facebook and others) make many participants restless and for many people the presence becomes a burden. (LOF)
