Evolution and Lamarck



Before Lamarck

Comparative anatomy  -  The study of similar morphological features across different species.
Creationism  -  The theory of the origin of life, which states that all life was created in its current form by God in a mass creation event that took place about 6000 years ago.
Inheritance of acquired traits (Lamarckian Inheritance)  -  The passing on of traits acquired during a parent's lifetime to offspring
Lamarckism  -  The theory of evolution stating that species change over time and that this change occurs through use and disuse and the inheritance of acquired traits.
Use and disuse  -  The Lamarckian evolutionary idea that if an animal often used a particular trait or characteristic, that trait or characteristic would become more pronounced. Alternately, if a trait went unused, it would become less pronounced.
