|Jean-Baptiste Lamarck evolution|
Jean-Baptiste Pierre Antoine de Monet, Chevalier de la Marck.
Naturalists including Lamarck naturally assumed that animals passed to their offspring characteristics that they acquired during their lives but Lamarck also believed that this explained evolutionary change. Lamarck taught that animals have a quality called besoin thought of as “want” or “need.” Generation after generation of animals gradually developed their abilities according to their besoin.
The need of the giraffe to graze on leaves at the tops of trees gradually created its long neck. The need of the rabbit to hop gradually developed its bigger haunches. The need of the hawk to eat the rabbit gradually grew its fast wings and sharp claws. The need of the socialite to snub her inferiors gradually turned up the noses of her well-off offspring. Over time, these things have improved our world to where we now live more satisfied and more sophisticated.
