Who proposed that the selective use or disuse of an organ led to a change the organ that was then passed to the offspring?
Jean-Baptiste Lamarck proposed this idea in his theory of inheritance of acquired characteristics. He suggested that organisms could pass on traits acquired during their lifetime to their offspring, leading to evolutionary change.
Who proposed that organisms acquired or lost traits during their lifetime by selective use or disuse of organs?
Jean-Baptiste Lamarck was the scientist who proposed the theory of acquired characteristics, suggesting organisms could acquire or lose traits during their lifetime through the use or disuse of certain organs. This theory was later replaced by Darwin's theory of evolution by natural selection.
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.
Who is the French naturalist who hypothesized that organisms acquire traits during their lifetime through use or disuse which can be passed on to their offspring?
Jean-Baptiste Lamarck is the French naturalist who proposed the theory of inheritance of acquired traits, also known as Lamarckism. He suggested that organisms can pass on traits that they acquire during their lifetime to their offspring.
What did Lamarck's idea of the inheritance of acquired traits propose?
First of all, Lamarck's theory of evolution of new species was wrong (disproved by various experiments). It stated that new species emerged by the use and disuse of organs. This, he called The Theory of Acquired Inheritance.For example, the ancestors of Giraffes found that all lower leaves on the trees were exhausted. So they started stretching their necks to reach higher leaves. Over the course of evolution, their neck length increased and thereby gave rise to modern day giraffes.Another similar example would be that of snakes. The ancestors of snakes had limbs. But they 'disused' the limbs and over the course of evolution, snakes emerged by the loss of limbs.Its worthy to remember that only the DNA in germ cells is inherited to the offspring and not that of somatic cells. So lamarckism is basically wrong because the changes in organs cannot be inherited by the offspring.Hope this helps.

Lamarck.
Who proposed that the selective use or disuse of an organ led to a change the organ that was then passed on to the offspring.?
Lamarck.
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 did Lamarck propose that species change over time?
Lamarck proposed that by selective use or disuse of organs, organisms acquired or lost certain traits during their lifetime. Then passed onto offspring-leading to change in species
Who proposed that the selective use or disuse of an organ led to a change the organ that was passed on to the off spring?
The idea that the selective use or disuse of an organ could lead to changes that are passed on to offspring was proposed by Jean-Baptiste Lamarck. This concept is often referred to as Lamarckism, which suggests that traits acquired or lost during an organism's lifetime could be inherited by future generations. Although Lamarck's theories were influential in the development of evolutionary thought, they have since been largely replaced by Darwinian natural selection.
What was Lamarck's 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
Can adaptation s occur throuh use and disuse?
Yes, the concept of adaptation through use and disuse was proposed by Jean-Baptiste Lamarck. He suggested that organisms could pass on acquired traits from use or disuse of certain organs to their offspring. However, this idea has been largely discredited in modern biology, as adaptation is primarily driven by natural selection acting on genetic variations.

Who propose use and disuse theory?
The use and disuse theory was proposed by Jean-Baptiste Lamarck, a French naturalist, in the early 19th century. Lamarck suggested that organisms could pass on traits acquired during their lifetime to their offspring. This theory contrasted with Darwin's theory of natural selection and is now largely discredited.
What idea proposed by Lamrack was later found incorrect?
Use and Disuse Theory
