What are the effects of natural selection on biological systems?

The effects of natural selection on biological systems are quite important. 

Natural selection ensures that living things adapt to their environment in the most appropriate way, enabling species to evolve. 

This process occurs through the selection and spread of traits that are passed down from generation to generation through the transfer of genes.

The effects of natural selection increase the adaptability of species, allowing them to adapt better to their environment. For example, if food resources in a species' habitat decrease, natural selection steps in to make individuals in that species better hunters and better fed. 

In this way, the species' chance of survival increases and its continuation is ensured.

Natural selection also helps species evolve by increasing genetic diversity. The adaptation of individuals with different genotypes to various environmental conditions creates a more solid foundation in the evolutionary process of the species. This increases the species' chance of long-term survival.

However, natural selection can also cause species to change. Rapid changes in environmental conditions can affect the adaptability of species, causing some species to disappear. 

This can lead to the disruption of biological balance and changes in the relationships between species in ecosystems.

The effects of natural selection on biological systems are quite complex. This process supports the evolution and adaptation of species and their adaptation to their environment. 

However, it can also cause species to change and lead to changes in the balance in ecosystems. Therefore, understanding and managing natural selection correctly is important to increase the survival chances of species.
