Why has lamack theory of evolutio been rejected?
Lamarck's theory of evolution has been largely rejected because it proposed that organisms could pass on traits acquired during their lifetime to their offspring, a concept known as inheritance of acquired characteristics. Modern genetics and evolutionary biology, particularly through the work of Charles Darwin and the development of the theory of natural selection, have shown that genetic variation arises through mutations and is inherited through genes, not acquired traits. Additionally, empirical evidence has consistently supported Darwinian evolution over Lamarckian ideas.

What was incorrect about Lamarck's hypothesis?
Lamarck proposed the idea of acquired traits being passed on to offspring, known as the inheritance of acquired characteristics. However, this concept has been proven to be incorrect through the science of genetics, which relies on the understanding of DNA and how traits are inherited through genes, rather than through an organism's interactions with the environment.
Are acquired characteristics evidence of evolution?
No, unless the mechanisms by which these traits are acquired are inherited, subject to variation, and found in patterns of nested hierarchies.
What are 2 acquired traits for a frog?

Which idea did lamarck propose that was rejected by his fellow scientists?
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 are Lamarcks's contributions to evolution?
Two pertinent ideas of Lamarck were the idea of acquired characteristics and the concept of use and disuse. Acquired characteristics posited that some experience that an organisms went through in life, such as muscle building due to hard work, would be heritable. Use and disuse posited that certain organs and traits could develop through use, such as the giraffe trying to eat the leaves on the heights of trees, or that organs or traits could be lost through disuse.
How does evolution by natural selection differ from lamarcks view of evolution?
Evolution by natural selection, proposed by Charles Darwin, suggests that individuals with advantageous traits are more likely to survive and pass on those traits to their offspring, leading to changes in populations over time. Lamarck's view of evolution, on the other hand, proposed the inheritance of acquired traits, where organisms could pass on traits that they acquired during their lifetime. The key difference is that in natural selection, the advantageous traits are already present in the population and selected for, while Lamarck's theory suggests that organisms can actively acquire and pass on new traits.
What kind of traits are traits that people deliberately change?
manipulated acquired traits
What aspect of Jean Baptiste Lamarcks theories concerning the inheritance of acquired traits has been proved false?
Lamarck believed that changes acquired during an animal's life could be inherited by their offspring. We now know that inheritance does not work in this way. For example, if you are a body builder, and develop big muscles, your children will not inherit large muscles. Inherirtance works through genes, which are inherited through the egg and sperm from the parents.

What is an example of traits that you would expect to inherit if Lamarck's explanation of evolution were correct?
if I were to inherit traits based on Lamarcks explanation of evolution were correct we wouldn't be the people we are now. Lamarcks´ explanation was that acquired characteristics were genetically passed to the offspring so if that were so, the human brains would be much more developed, more knowledge, and bigger parts of the body. This question is also tricky since a human would turn out to be a giant by the time they got to the 100th offspring

What is acquired traits?
Acquired traits are characteristics or traits that an organism develops during its lifetime as a result of environmental influences or experiences. These traits are not inherited genetically and cannot be passed on to offspring. Examples of acquired traits include language skills, knowledge, and physical changes due to exercise.
