Lamarck proposed that traits acquired during one's lifetime could be passed to the next generation.
They developed their ideas around the year 1850.
Charles Darwin's theory of evolution by natural selection influenced the eugenics movement by providing a scientific basis for the idea of improving the human race through selective breeding. Some eugenicists misinterpreted Darwin's ideas to justify their beliefs in promoting "good" traits and eliminating "undesirable" traits in the human population.
What were 2 ideas from the Enlightenment that influenced the Declaration of Independence?
the political ideas that influenced the revolution was that they ( patriots or loyalists) wanted to be independent.
These ideas were influenced by the Athenian democracy.
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.

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 was influenced by ideas from other scientists such as Lamarck's theory of acquired traits and Malthus's principle of population. These ideas contributed to Darwin's concept of natural selection as the mechanism for evolution. Ultimately, Darwin's observations and synthesis of these ideas led him to develop his theory of evolution by natural selection, which revolutionized the field of biology.
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.
Darwin's ideas diverged from Lamarck's primarily in their mechanisms of evolution. While Lamarck proposed that traits acquired during an organism's lifetime could be passed on to offspring (the inheritance of acquired characteristics), Darwin introduced the concept of natural selection, where variations that enhance survival and reproduction are more likely to be passed on. Darwin emphasized random genetic variation and the survival of the fittest, whereas Lamarck focused on purposeful adaptations. This fundamental difference laid the groundwork for modern evolutionary biology.
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.

Darwin's ideas diverged from Lamarck's primarily in their explanations of how species evolve. While Lamarck proposed that organisms could inherit traits acquired during their lifetimes (Lamarckism), Darwin introduced the concept of natural selection, where variation within a population leads to differential survival and reproduction. This mechanism emphasizes the role of genetic variation and environmental pressures rather than acquired characteristics. Thus, Darwin's theory provided a more scientifically grounded understanding of evolution based on observable processes.
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.
One idea that is not one of Darwin's four main concepts of natural selection is the concept of "inheritance of acquired characteristics," which was proposed by Lamarck. Darwin's four main ideas include variation within populations, competition for resources, survival of the fittest, and the inheritance of favorable traits. Unlike Lamarck's theory, Darwin emphasized that traits are passed down through genetic inheritance rather than acquired through an individual's lifetime.
One idea that is not one of Darwin's four main concepts of natural selection is the inheritance of acquired characteristics, which was proposed by Lamarck. Darwin’s main ideas focus on variation among individuals, the struggle for existence, survival of the fittest, and the gradual process of evolution through natural selection. In contrast, Lamarck's theory suggests that organisms can pass on traits acquired during their lifetime, which is not supported by contemporary genetics.
