Why was Lamarck's theory of evolution not eccepted?
Not well supported by the evidence and basically just assertion. Lamarck asserted that acquired characteristics, such as muscles developed during one's lifetime, were heritable. They are not. He also asserted that an organism had a " desire " to evolve. This was also not true.
What was incorrect about Lamarck's hypothesis?
It is true that certain anatomical structures change in size according to use, but these changes cannot be passed on to the organism's offspring.
Did Darwin or Lamarck hypothesized that characteristics developed by parents are passed on to their offspring?
?Mendel, widely acknowledged as the first geneticist.the answer is either lamarck or darwinit's lamarck. he believed that characteristics developed by parents are passed on to their offspring.
Why does jean-baptiste lamarck's theory was not immediately accepted by the public?
The public, due mostly to religious reasons, was not ready for any transmutational theory and Lamarck's theory had no evidence to support it thus scientists of the time did not pay it much attention. Also Cuvier was Lamarck's enemy and denigrated the theory Lamarck developed.
What the microscope contribute to the study of different objects and organism?
The microscope makes transparent objects visible to enable study.
What idea did Lamarck and William smith contribute to the study of fossils?
Lamarck's ideas were that he had a great contribution to the study of evolution.
What was lamarck's incorrect hypothesis regarding inheritance?
Lamarck's incorrect hypothesis regarding inheritance.... Lamarck did not know how traits were inherited (Traits are passed through genes) Genes are not changed by activities in life. They change through mutation occurs before an organism is born.
Was Lamarck correct?
Lamarck was correct about the connection between the environment and evolution. He saw that the organism changes based on the environment and its survival. However, Lamarck is not well-known for his advances in the field. Instead, he is known for the incorrect mechanisms for evolution that he proposed, including "use and disuse" and "inheritance of acquired characteristics." (A small note, Lamarck definitely did not have a "theory," he had hypotheses).
What is the study of function in a biological organism?
Physiology is the study of an organism's function.
What is Lamarckism?

What is the smallest unit of ecological study?
It is organism.
Do we use Jean-Baptiste Lamarck's ideas on evolution today?
No. Although recently a new field of reseach has sprung up in biology: epigenetics, the study of heritable changes that are not transmitted through RNA/DNA, this has little to do with Lamarck's theory.
What means lamarckism?
Lamarck give the idea that an organism can pass on their characteristics that it have acquired during its lifetime to its offspring. Also known as heritability of acquired characteristics.
