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.

His theory was that animals changed themselves to better suit the environment after the environment changed. They passed these changes or "adaptations" to their offspring. This is incorrect because when an animal was not fit for its environment, it died and was not able to change itself of change its future offspring. It died because it was not fit for its habitat. This is known as natural selection.

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
Evolution is a change in species over time.
Species not always change over time such sponges :D

Charles Darwin
The punctuated equilibrium hypothesis is a theory that most species have little evolutionary change throughout their geological history. They will remain in a state of stasis.
you change the hypothesis.
Discard or change the hypothesis.
Change or abandon your hypothesis.
natural selection
No, because it is a statement with a history, if it is wrong it is superseded by a new hypothesis.

It is important to be able to test the hypothesis because testing your hypothesis is how you prove or disprove your theories. If it is disproved then you can change your hypothesis.
