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.
Jean- Baptiste Lamarck
Jean-Baptiste Lamarck believed in the theory of inheritance of acquired characteristics, which proposed that organisms could pass on traits that they acquired during their lifetime to their offspring. He also believed in the idea of evolution, suggesting that organisms change over time in response to their environment. However, Lamarck's ideas have been largely discredited in favor of Charles Darwin's theory of natural selection.
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 was a French naturalist known for his early theory of evolution, which emphasized the idea of inheritance of acquired characteristics. He proposed that organisms could pass traits acquired during their lifetime to their offspring, suggesting that environmental changes drove the evolution of species over time. His ideas were among the first to challenge the static view of species, although they were later largely overshadowed by Charles Darwin's theory of natural selection. Lamarck's work laid important groundwork for the development of evolutionary biology.
Charles Darwin was influenced by several key figures, including Jean-Baptiste Lamarck, whose ideas on evolution and inheritance laid foundational concepts for Darwin's theories. Thomas Malthus also played a significant role, as his writings on population growth and resource limitations prompted Darwin to consider natural selection as a mechanism for evolution. Additionally, Charles Lyell's principles of geology, emphasizing gradual change over time, helped Darwin understand the long timescales necessary for evolution to occur.

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.
Alfred Russel Wallace,Charles Darwin built the theory of Evolution.Jean-Baptiste Lamarck's ideas also helped.
Jean- Baptiste Lamarck
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.
it's likely that organisms, including bacteria are always changing
scientist whose ideas about evolution were the same as Darwin's- Wallace geologist who influenced Darwin- Lyell geologist who influenced Darwin- Hutton scientist whose ideas about evolution and adaptation influenced Darwin- Lamarck economist whose ideas about human population influenced Darwin-Malthus
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.
Charles Darwin is credited with this theory in his book, The Origin Of Species. ---> Actually... Jean-Baptiste Pierre Antoine de Monet, Chevalier de la Marck (AKA Lamarck) was the first to propose the hypothesis that species change over time.

Jean-Baptiste Lamarck believed in the theory of inheritance of acquired characteristics, which proposed that organisms could pass on traits that they acquired during their lifetime to their offspring.

However, Lamarck's ideas have been largely discredited in favor of Charles Darwin's theory of natural selection.
Jean Baptiste Lamarck's work proposed the theory of inheritance of acquired traits, where individual organisms can pass on traits acquired during their lifetime to their offspring. This theory influenced early evolutionary thought but was largely replaced by Charles Darwin's theory of natural selection. Lamarck's work highlighted the idea of organisms adapting to their environment, sparking further discussion in the field of biology.
