Who believed that organisms inherited acquired characteristics?

Jean-Baptiste Lamarck believed that organisms inherited acquired characteristics.

Explanation:

The French naturalist and biologist Jean-Baptiste Lamarck has done huge work to discover the concept for his Acquired Characteristic Inheritance Concept, which was first articulated in 1801. When, throughout lifespan, an organism evolves to adjust to its atmosphere, those adjustments are carried on to its offspring.

He declared that variations comes about through what the species need or want. For instance, he assumed that elephants ought to all have short trunks. In the absence of food or water they could touch with their short trunks, they spread out their trunks to meet the water and branches and inherited long trunks from their descendants. He also claimed that parts of the body which are not utilized, like the human appendix and the tiny toes, slowly disappear.
