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.
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.
In Darwin's theory, natural selection plays the key role. Organisms vary through random mutations--slight changes from their parents. The environment determines which are most likely to survive. In Lamarck's theory, changes in phenotype are inherited. This is now known to be (largely) incorrect.
Lamark believed that behaviors learned by parents could become inheritable traits.
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.
Lamarck's Hypothesis of Evolution(Small note before answer: Lamarck had a hypothesis, not a theory) Lamarck, as well as other naturalists, hypothesized evolution via environmental change before Darwin. However, many failed to account for changes in the fossil record and interactions of the phenotypes of animals on their environment. Despite Lamarck's advances in the field, he is most remembered in history for the incorrect mechanisms of this evolution that he posited.Lamarck's hypothesis of evolution appeared in his Zoological Philosophical Work written in 1809, featuring two mechanisms of evolutionary change: use and disuse and inheritance of acquired characteristics.His evolutionary hypothesis was as follows:Environmental changes generate new needsThese needs determine the use or disuse of some organsSuch organs develop or are diminishedThe acquired characters are hereditary
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.

Animal behaviors are not inheritable.

Lamarck's hypothesis about evolution was that animals would change based on their environment during their lifetime and pass on those traits to their offspring. This is different from Darwin's theory in that all animals mutate in someway and it's the surviving mutations that pass on that slowly change the animal over many generations.
he was different because lamarck was using already true things to prove something and wallace was a theorist

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
