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.

What is Lamarck's principle of use and disuse?
Lamarck's principle of use and disuse proposes that organisms can acquire or lose certain traits based on how much they use or do not use them during their lifetime. In other words, Lamarck suggested that characteristics developed during an individual's lifetime can be passed on to their offspring. This idea contrasts with modern understanding of genetics, which is based on the transmission of genetic information through DNA from parents to offspring.
Has Lamarck's theory of evolution been proved?
Scientists do not prove things. Lamarck's theory is long refuted as acquired characteristics and the use and disuse concepts are not explanations for evolution of populations.
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 is the base of lamarck theory?
The two concepts of the inheritance of acquired characteristics plus use and disuse of traits.
What has been proved false about Jean Baptiste lamarck's theories?
His concepts about acquired characteristics and use and disuse.
What were the two ideas proposed by Lamarck to explain the mechanism of evolution?
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.
Explain lamarck principle of use and disuse?
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

How would Lamarck explain the development of giraffes with long necks?
Lamarck would explain the development of giraffes with long necks as a result of the giraffes stretching their necks to reach higher leaves, and passing on this acquired trait to their offspring. This is known as the theory of inheritance of acquired characteristics.
