Lamarck proposed the theory of inheritance of acquired characteristics, suggesting that organisms could pass on traits acquired during their lifetime to their offspring. For example, he believed that a giraffe's long neck evolved because ancestors stretched to reach higher leaves, and this trait was then inherited by subsequent generations. However, Lamarck was wrong because modern genetics shows that traits are inherited through genes, not through acquired characteristics, as changes to an organism's phenotype during its life do not alter its genotype. Thus, evolutionary changes occur through natural selection and genetic variation, rather than through individual life experiences.
What else can I help you with?
Was lamarcks idea of acquired traits proven or rejected?
rejected.
Which of lamarcks ideas was later found to be incorrect?
The idea of acquired characteristics. For instance. The idea that a blacksmith, who would develop enormous muscles due to his trade, could pass these physical attributes on to his children.
What was Lamarcks theory of how things changed over time?
Lamarck's theory, known as Lamarckism, proposed that organisms evolve through the inheritance of acquired characteristics. He suggested that traits developed 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 emphasized the role of adaptation to the environment in driving evolutionary change. While Lamarck's theory was influential, it has since been largely discredited in favor of Darwinian evolution and natural selection.
What was Lamarcks law of use and disuse?
Lamarck's law of use and disuse, proposed by the French biologist Jean-Baptiste Lamarck in the early 19th century, suggests that traits or characteristics that are frequently used by an organism become stronger or more developed, while those that are not used may weaken or diminish over time. This idea implies that organisms can pass on acquired characteristics to their offspring. Although Lamarck's theory was a precursor to the modern understanding of evolution, it has largely been discredited in favor of Darwinian natural selection.
What was incorrect about lamarcks thery of how organisms evolved?
Lamarck's theory of evolution, known as Lamarckism, proposed that organisms could pass on traits acquired during their lifetime to their offspring, a concept known as "inheritance of acquired characteristics." This idea was incorrect because it suggested that changes acquired through use or disuse, such as a giraffe stretching its neck to reach higher leaves, could be inherited, which contradicts modern genetic understanding. Evolution is now understood to occur through genetic mutations and natural selection, where traits are passed down based on genetic inheritance rather than acquired characteristics.
Was lamarcks idea of acquired traits proven or rejected?

How is lamarcks theory of evolution different from theory of evolution?
Make me cum daddy~! Make me moan~!
Why does each man have the wrong idea about the elephant?
Each man has the wrong idea about the elephant as they are blind and feel the different parts of the elephant's body.
What is the idea between englishness and otherness?
The idea is that Englishness is right and otherness is wrong.
What parts of Lamarcks hypotheses have been proved wrong?
Lamarck's hypothesis of the inheritance of acquired characteristics has been largely disproven. Scientific research has shown that physical changes acquired during an organism's lifetime are typically not passed on to offspring. Additionally, Lamarck's idea of evolution occurring in a linear, progressive manner has also been challenged by the modern understanding of evolution as a more complex and branching process.
What is an idea that can be tested by a scientific investigation?
An idea like that is in a scenario when research on the idea can prove it right or wrong.
What does misconseption mean?
