Lamarck proposed the idea of the inheritance of acquired characteristics, suggesting that organisms could pass on traits acquired during their lifetime to their offspring. For example, he believed that if an organism developed a characteristic through use or disuse, such as a giraffe stretching its neck to reach higher leaves, that trait would be inherited by its descendants. This concept was rejected in favor of Darwin's theory of natural selection, which emphasizes genetic variation and heritable traits rather than acquired characteristics. Modern genetics has further supported the idea that acquired traits do not alter an organism's DNA in a way that can be passed to future generations.

Lamarck proposed the idea of inheritance of acquired characteristics, suggesting that traits acquired during an organism's lifetime could be passed on to its offspring. For example, he believed that if an organism developed a characteristic through use or disuse, such as a giraffe stretching its neck to reach higher leaves, that trait would be inherited by its offspring. This concept was largely rejected by fellow scientists, as it contradicted the emerging understanding of genetics and natural selection, particularly as formulated by Darwin. Instead, it was established that genetic traits are inherited through genes, not through acquired characteristics.
Which idea did lamark propose that was rejected by his fellow scientists?
Lamarck proposed the idea of the inheritance of acquired characteristics, suggesting that traits acquired during an organism's lifetime could be passed on to its offspring. For example, he believed that if a giraffe stretched its neck to reach higher leaves, its offspring would inherit a longer neck. This concept was largely rejected by scientists in favor of Darwin's theory of natural selection, which emphasizes genetic variation and survival of the fittest rather than the inheritance of traits acquired during an individual's lifetime.
How did Jean Baptiste Lamarck influence Charles Darwin?
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.
How did lamarck's theory affect Darwin's thinking?
Lamarck's theory of inheritance of acquired characteristics influenced Darwin by introducing the idea that organisms could change over time in response to their environment. Although Darwin ultimately rejected Lamarck's mechanisms, he was inspired by the concept of adaptation and the idea that species are not fixed. This led him to explore natural selection as a more robust explanation for how species evolve and adapt. Thus, while Darwin diverged from Lamarckism, he acknowledged its role in shaping his thoughts on evolution.
Was lamarcks idea of acquired traits proven or rejected?
rejected.
Which idea did Lamarck propose that was rejected by fellow scientist?
That organisms pass on traits acquired in their lifetimes. It was rejected in favour of Darwinian evolution, in which species and not individuals evolve, but Larmarckism is valid to a point where epigenetics is concerned.

What did lamarck propose a scientific explanation for?
Lamarck hypothesized that organisms evolved through the inhertitance of acquired charactaristics.

Was lamarck's theory accepted or rejected?
His theory of use and disuse was rejected.
What did Lamarck propose a scientific explanation for and why?
Lamarck proposed a scientific explanation for evolution because organisms evovled through the inherititance of acquired charactaristics.
