Jean-Baptiste Lamarck published his ideas on evolution in 1809 in his work titled "Philosophie Zoologique." In this book, he introduced the concept of inheritance of acquired characteristics, proposing that organisms could pass on traits acquired during their lifetime to their offspring. Lamarck's ideas were among the earliest theories of evolution, predating Charles Darwin's work by several decades.
The basic one of evolution. That organisms change over time.
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.

Jean-Baptiste Lamarck published his ideas on evolution in 1809 in his work titled "Philosophie Zoologique." In this book, he introduced the concept of inheritance of acquired characteristics, proposing that organisms could pass on traits acquired during their lifetime to their offspring. Lamarck's ideas were among the earliest theories of evolution, predating Charles Darwin's work by several decades.
Jean-Baptiste Lamarck, a French biologist, proposed the idea of inheritance of acquired characteristics and the concept of transformational evolution. These ideas influenced Darwin's thinking on evolution and adaptation. However, Darwin's theory of natural selection ultimately diverged from Lamarck's ideas.
Lamarck's ideas were that he had a great contribution to the study of evolution.

The basic one of evolution. That organisms change over time.
Darwin did not actually meet Lamarck in person. Lamarck's ideas on evolution were published before Darwin's time, and Darwin was familiar with them through his readings. Darwin's theory of natural selection differed from Lamarck's theory of inheritance of acquired characteristics.
Jean-Baptiste Lamarck proposed two ideas to explain the mechanism of evolution: the inheritance of acquired traits and the use and disuse of organs. According to Lamarck, organisms could pass on traits they acquired during their lifetime to their offspring, and that the use or disuse of certain organs could lead to changes in those organs over time.
Lamarck proposed the idea of "inheritance of acquired characteristics," suggesting that organisms can pass on traits acquired during their lifetime to their offspring. He believed that these acquired traits could lead to evolutionary change over time. However, his ideas have largely been discredited in favor of Darwin's theory of natural selection as the primary mechanism of evolution.
No. Although recently a new field of reseach has sprung up in biology: epigenetics, the study of heritable changes that are not transmitted through RNA/DNA, this has little to do with Lamarck's theory.
Lamarck proposed the theory of inheritance of acquired characteristics, suggesting that organisms could pass on traits acquired during their lifetime to their offspring. He also proposed that the environment could drive changes in an organism's structure and function over time, leading to evolution. However, his ideas were largely discredited with the acceptance of Darwin's theory of natural selection.
Lamarck's ideas about evolution include the concept that differences among the traits of organisms arise as a result of the use or disuse of those traits. This concept is known as the inheritance of acquired characteristics or the theory of soft inheritance. According to Lamarck, organisms can pass on traits that they acquire during their lifetime to their offspring.
