As early as the 9th century, it was suggested when organisms change, they may be better able to adapt to survive.

Explanation:

JB Lamarck published the 'Système des animaux sans vertèbres' in 1801, for the first time presenting the idea of the common origin of organisms and their gradual development, which he developed in 1809 in the well-known work 'Philosophy zoologique - a complete evolutionary theory'. According to Lamarck, there is a slow, continuous process of species transformation in nature. Lamarck reduces the factors that condition this process to the environmental changes that influence the animal's needs, and thus acquires new habits. In accordance with new habits and needs, some organs are more widely used and developed; conversely, not using the organs causes them to weaken and disappear in the newly born offspring.
