Evolution and Lamarck Before Lamarck For much of history, the idea of evolution did not exist. Short-term observations of the natural world showed that while there was a great diversity of living things, they generally stayed the same generation after generation.

According to this text, God created all animals individually and simultaneously. All animals were created in forms perfectly suited to their environments and purposes in the natural world. This mass creation event was believed to have occurred about 6000 years ago.

In the short span of written history, species did not seem to change, but rather seemed to have fixed forms that were indeed well suited to

Fossilized bones of animals never before seen were unearthed. These and other types of evidence cast doubt on creationism, leading scientists on a search for a new explanation that would eventually bring Lamarck and Darwin to create their theories of evolution. These lines of evidence are still used today in the study of evolution and are discussed in evidence of evolution .
