Etymology
Lamarck comes from the name of a French scientist, Jean-Baptiste Lamarck, who suggested that animals and plants can 'pass on' changes they 'gain' during their life, like a neck that grows longer from stretching. So, in biology Lamarck usually stands for the idea that living things pass their life changes to their children.
