Remember what variability is. What effect do environmental conditions have on the formation of traits in organisms

Variability – the ability of an organism to change under the influence of various conditions, which in the process of evolution leads to a change in the characteristics and properties of the organism and even the appearance of new ones and serves the survival of the species. The external environment determines the processes of selection, variability and heredity, i.e. evolutionary factors. In accordance with changes in the environment, the whole organic world developed. Thanks to this, each type of organism has acquired a peculiar internal structure and its inherent type of individual development, fixed by heredity.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
