Lamarck thought that evolution could be effected by changes in the body, rather that strictly by the survival (or rather the death) of offsprings.
early 1800s
Scientists do not prove things. Lamarck's theory is long refuted as acquired characteristics and the use and disuse concepts are not explanations for evolution of populations.

Lamarck thought that evolution could be effected by changes in the body, rather that strictly by the survival (or rather the death) of offsprings.
Lamarck's hypotheses were published in Zoological Philosophical Work written in 1809.
early 1800s
Lamarck's ideas were that he had a great contribution to the study of evolution.
Jean-Baptiste Lamarck was the first person to clearly formulate and present a plausible theory of evolution. Lamarck was a French naturalist who lived from 1744 to 1829.

Fossils or natural selection
Jean Lamarck's theory of evolution is known as zoological philosophy or the inheritance of acquired characteristics, and stated that changes to an organisms phenotype (basically what it looks like) will cause changes to it's genotype (DNA). This has been disproved of by modern scientists, with natural selection as the main theory.

Lamarck was correct about the connection between the environment and evolution. He saw that the organism changes based on the environment and its survival. However, Lamarck is not well-known for his advances in the field. Instead, he is known for the incorrect mechanisms for evolution that he proposed, including "use and disuse" and "inheritance of acquired characteristics." (A small note, Lamarck definitely did not have a "theory," he had hypotheses).
