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 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.
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?
Jean-Baptiste Lamarck proposed the theory of the inheritance of acquired characteristics, which suggests that the use or disuse of an organ could lead to changes in that organ that are then passed on to the offspring. This theory was later found to be inaccurate in light of modern genetics and the principle of inheritance through DNA.
What can predict whether a mutation in a human skin cell can be passed to its offspring?
A mutation in a human skin cannot be passed on to an offspring, since it is only a somatic mutation which is acquired. The mutation that can be passed on to an offspring is called a germline mutation, which happens in the egg and sperm.
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.
Who proposed the acquired traits could be passed on to an organisms offspring?
Lamark
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.
Which is true about adaptions?
They are passed along to offspring.
What did Jean Baptiste Lamarck discover?
Jean Baptiste Lamarck proposed the theory of inheritance of acquired characteristics, suggesting that traits acquired during an organism's lifetime could be passed on to its offspring. He also investigated the relationship between organisms and their environment, contributing to our understanding of evolution.
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
Lamarck proposed that organisms?
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.

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
The mutations that breeders induce in organisms are passed on to the organisms?
offspring
Why is lamarck's theory not supported by the theory of natural selection?
Lamarck thought that traits organisms acquired during their lifetime would be passed on to offspring. He believed that traits were determined by use or disuse. However, acquired traits cannot be passed on to offspring; only traits determined by DNA can
What is the role environment in Lamarck's explanation?
In Lamarck's explanation of evolution, the environment plays a role in shaping the traits of organisms through the principle of use and disuse. Lamarck proposed that organisms could acquire or lose certain traits based on their interactions with the environment during their lifetime, and these acquired traits could be passed on to their offspring. This theory is known as the inheritance of acquired characteristics.
Who proposed the idea of inheritance of acquitted characteristics?
Jean-Baptiste Lamarck, a French biologist, proposed the idea of the inheritance of acquired characteristics as part of his theory of evolution in the early 19th century. He believed that traits acquired during an organism's lifetime could be passed on to offspring.
