Both Lamarck and Darwin contributed significantly to the understanding of evolution, emphasizing the adaptation of species to their environments. They recognized that organisms change over time, although their mechanisms differed: Lamarck proposed the inheritance of acquired characteristics, while Darwin introduced natural selection as the primary driver of evolution. Both theories acknowledge the importance of environmental influences on species, highlighting a shared interest in how life evolves. Ultimately, while their explanations diverged, they both sought to explain the diversity of life on Earth.
Lamarck used the term "inheritance of acquired characteristics" to explain how organisms could pass on traits they acquired during their lifetime to their offspring. He believed that environmental challenges would lead to physical changes in an organism, which could then be inherited by future generations. This idea was a significant early contribution to evolutionary thought, although it was later largely replaced by Darwin's theory of natural selection.
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.
Jean-Baptiste Lamarck was a French naturalist known for his early theories of evolution, which emphasized the idea that organisms adapt to their environments through the inheritance of acquired characteristics. He believed that changes in an organism's environment lead to changes in its behavior, which in turn would result in physical modifications that could be passed down to future generations. Lamarck's work aimed to explain the diversity of life and the mechanisms behind evolutionary change long before Darwin's theory of natural selection gained prominence. His ideas laid an important foundation for the study of evolution, despite being later overshadowed by more scientifically robust theories.
Lamarck did. Neodarwinism theorises that species evolve when gene frequencies change, not individual organisms. Larmarkism is true for epigenetic inheritance, favourable and unfavourable characteristics alike.
Lamarck hypothesized that organisms evolved through the inhertitance of acquired charactaristics.
Lamarck.
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 that by selective use and disuse of organs, organisms acquired or lost certain traits during their lifetime. These traits could then be passed on to their offspring. Over time, this led to a change in species

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.
Lamarck proposed a scientific explanation for evolution because organisms evovled through the inherititance of acquired charactaristics.
he proposed the organisms pass on "acquired characteristics" such as playing the piano.
Obviously he was wrong. Organisms evolve, Evolution is not progressive, does not plan for the future and is not linear. The average tendency is for organisms to become more complex, but someone forgot to tell barnacles and tape worms, among others, as they have got less complex. Evolution is only change over time and Lamarck was wrong about ' improvements. '
