What were lamark's theories?
Jean-Baptiste Lamarck proposed the theory of inheritance of acquired characteristics, which suggests that traits acquired during an organism's lifetime can be passed on to its offspring. He also proposed the idea of use and disuse, where organs that are used frequently become more developed while those that are not used deteriorate over time. However, Lamarck's theories have largely been discredited in favor of Darwin's theory of natural selection.
Where did Lamarck and Darwin agree on the evolution theory?
Lamarck and Darwin both agreed that species evolve over time and that this process leads to the adaptation of organisms to their environments. They recognized the importance of environmental factors in shaping traits and behaviors. However, while Lamarck proposed the inheritance of acquired characteristics as the mechanism for evolution, Darwin introduced natural selection as the primary driving force, marking a fundamental difference in their theories.
Lamarck proposed two ideas to explain?
Lamarck proposed two key ideas to explain evolution: the inheritance of acquired characteristics and the notion of organisms striving for perfection. He suggested that traits acquired during an organism's lifetime, such as a giraffe stretching its neck to reach higher leaves, could be passed on to its offspring. This idea contrasted with Darwin's theory of natural selection, which emphasizes genetic variation and survival of the fittest as the primary drivers of evolution. Despite being foundational, Lamarck's theories have largely been discredited in light of modern genetics.
What did lamarck study?
Jean-Baptiste Lamarck was a French naturalist best known for his early theories of evolution, particularly the concept of inheritance of acquired characteristics. He studied various organisms, including plants and invertebrates, and proposed that traits developed during an organism's lifetime could be passed to its offspring. This idea contrasted with Darwin's theory of natural selection, and although Lamarck's specific mechanisms were later discredited, his work laid important groundwork for evolutionary biology.
What has been proved false about Jean Baptiste lamarck's theories?
His concepts about acquired characteristics and use and disuse.

What were the main ideas Lamarck proposed that influenced Darwin?
Lamarck proposed that traits acquired during one's lifetime could be passed to the next generation.

Which scientist suggested the theory of swordfish?
Lamarck
What scientist had ideas about evolution and adaptation that influenced Darwin?
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.
What are the same between Darwin and lamarck?
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 proposed that organisms have what?
he proposed the organisms pass on "acquired characteristics" such as playing the piano.
Lamarck proposed that organisms?
Lamarck proposed that organisms developed new features as a result of a 'inner urge' for improvement and that they passed on these improvements to their young/offspring. He did not accept that animals could become extinct.
Who was jean De Lamarck?
Jean-Baptiste de Lamarck was an 18th-century French naturalist best known for his early theories of evolution. He proposed the idea of the inheritance of acquired characteristics, suggesting that organisms could pass traits acquired during their lifetime to their offspring. Lamarck's ideas laid the groundwork for later evolutionary theories, although they were largely overshadowed by Charles Darwin's natural selection. He also made significant contributions to the fields of invertebrate biology and ecology.
