Histoire Naturelle Des Animaux Sans Vertebres

Best known for his ideas relating to evolution French naturalist Jean-Baptiste Lamarck (17441829) first built his reputation as a botanist and was elected to the prestigious Acadmie des Sciences in 1779. His career took a new turn in 1793 when he was made professor of ''insects worms and microscopic animals'' at the Musum National d''Histoire Naturelle although he lacked prior knowledge of the subject area. Undaunted Lamarck set out to classify organisms which few naturalists had considered worthy of study since Linnaeus. He was the first to distinguish vertebrates from ''invertebrates'' a term he coined by the presence of a vertebral column. In this groundbreaking seven-volume work published between 1815 and 1922 he arranges invertebrates into twelve classes laying the foundations for the modern study of these organisms. Volume 3 first published in 1816 covers tunicates worms and insects.
