Each organism (individual) carries a particle of the gene pool (its genotype) of the population. With each new crossing, the individual receives a completely new genotype. This is a unique role of organisms that carry out the process of constant updating of hereditary properties in new generations due to sexual reproduction. One individual cannot evolve, it gives a “push” to the whole population. It can change, adapting to environmental conditions, but these are not inherited signs. Organisms, like no other form of living matter, are able to sense the external world, the state of their body and respond to these sensations, directionally changing their actions in response to irritation coming from external and internal factors. Organisms can learn and communicate with individuals of their kind, build homes and create conditions for breeding cubs, show parental care for offspring.
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.
