The idea of acquired characteristics. For instance. The idea that a blacksmith, who would develop enormous muscles due to his trade, could pass these physical attributes on to his children.
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.
Lamarck's theory is disproved through many different examples of acquired characteristics. Anything that happens to a parent would be passed on to the offspring. Acoording to Lamarck, a parent that has tattoos would pass on the tattoos to the offspring. Loss of limb, injuries, cosmetic surgery or anything that changed in the parents would manifest in the offspring. This is not the case. Acquired characteristics are not passed on to offspring unless they change the gene sequence of the sex cells. Parents do not give physical characteristics to offspring, but do give the coding for those characteristics. The gene passes on the trait.
This is a theory that states that some characteristics of an individual are acquired as opposed to inherited. For example, some frogs have mutations because of pollutants in their environment, whereas a person who has blue eyes probably has them because they inherited them from their parents.

Lamarck's idea of how evolution works was through inheritance of acquired characteristics which stated that offspring get the modifications acquired by parents. Further, he believed in "use and disuse", which stated that using a part of the body will make it bigger and stronger, while disuse will make it smaller (such as appendix). Of course, these ideas were strongly rejected in favor of natural selection.
The idea of spontaneous generationis incorrect because non-living things can not produce living things.
Larmark's theory was based on the idea that organisms inherited characteristics that they had acquired in life - so, if you have a scar your offspring will have scars. Darwin's theory assumed that offspring inherited characteristics from their parents, but they were more likely to survive to breed if there was advantage to those characteristics.

"Inheritance of acquired traits", one of the implications of this would be that if an individual broke a bone and it did not heal correctly then that individual's children would likely be born with this "new acquired trait" of that bone already broken and improperly healed instead of having a normal bone in that location.
an organism can pass on characteristics that it acquired during its lifetime to its offspring. He was also an early proponent of the idea that evolution occurred and proceeded in accordance with natural laws.
