That they were both transformationists, a word the meant in those days one thought organisms evolved over time, and thought species arose by natural processes. The mechanisms proposed by them varied a great deal though.
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.
Scientists before Darwin, such as Lamarck and Lyell, influenced Darwin's ideas by presenting concepts like geology and the idea of species change over time. Lamarck's theory of acquired characteristics and Lyell's principles of uniformitarianism provided a basis for Darwin to develop his theory of evolution through natural selection. Darwin built upon these ideas by incorporating them into his own theory, which became the foundation of modern evolutionary biology.
Some scientists and researchers who influenced Charles Darwin include Thomas Malthus, Jean-Baptiste Lamarck, and John Gould. Malthus's theories on population dynamics and resources helped shape Darwin's ideas on natural selection. Lamarck's proposal of the inheritance of acquired traits also impacted Darwin's thinking. John Gould's work on the Galapagos finches provided Darwin with important evidence for his theory of evolution.
French naturalist Jean-Baptiste Lamarck's theory of evolution conflicted with Darwin's theory. Lamarck proposed that acquired characteristics could be passed down to offspring, while Darwin's theory emphasized natural selection and gradual change over generations.
Both Lamarck's theory of inheritance of acquired traits and Darwin's theory of evolution by natural selection were important because they laid the foundation for understanding how species change over time. Lamarck proposed that organisms could acquire traits during their lifetime and pass them on to their offspring, while Darwin's theory explained how species adapt to their environment through a process of natural selection. These theories revolutionized the field of biology and continue to influence our understanding of the diversity of life on Earth.
i would agree with you. i belive they both had the same theory.
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.
Darwin read the book Lamarck wrote and said that he did not get one idea from it as it was ludicrous in content. So, Lamarck would be the one scientist that did not influence Darwin according to Darwin.

Darwin, of course. Lamarck did not have the evidence to back up his acquired characteristics and use and disuse concepts, but Darwin had massive amounts of evidence and well structured arguments for his theory of natural selection.
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.
Jean Baptiste Lamarck's idea of the inheritance of acquired characteristics, although mostly rejected today, was one of the first systematic explanations for evolution, influencing Darwin's thinking. While Darwin's theory of natural selection differed significantly from Lamarck's, Lamarck's work helped pave the way for questioning and exploring evolutionary mechanisms that ultimately led to Darwin's own theory of evolution by natural selection.

Darwin's theory made more sense and was proven true.
