Natural selection

Natural selection: the main factor in the evolution of living nature

Natural selection is a key factor in the evolution of living organisms. It is a process of preferential survival of individuals that are best adapted to specific environmental conditions. This process leads to changes in the expression of various traits over a number of generations of the population.

The idea of ​​natural selection was proposed by Charles Darwin in his book On the Origin of Species in 1859. Darwin noted that in nature there is competition for limited resources such as food, water and space to live. He theorized that individuals that were better adapted to their environment would be more likely to survive and pass on their genes to the next generation.

Natural selection can lead to various changes in a population. For example, if the environment becomes drier, then individuals with longer roots may be more likely to survive and produce offspring. Thus, in the next generation of the population we can expect more individuals with longer roots.

Natural selection can also lead to the development of new traits in organisms. For example, if a bird population is faced with the need to forage for food in difficult to reach areas, then individuals with longer and thinner beaks may have an advantage. As a result of natural selection, an increase in the length and thinness of the beak can be expected in the next generations of the population.

Natural selection is the main factor in the evolution of living nature. It can lead to various changes in the population, which may be beneficial or disadvantageous to the organisms depending on environmental conditions. This process is continuous and continues throughout the life of the population. As a result of natural selection, a variety of life forms on Earth arises, which are adapted to different environmental conditions.



Natural selection is the preferential survival and reproduction of individuals that are more adapted to specific environmental conditions and have certain characteristics that distinguish them from other representatives of the species. Natural selection is one of the main factors determining the evolution of living organisms, and serves to increase viability, increase reproductive capacity and prevent the extinction of species
