Cenozoic Era–Mammal evolution examples

Horses:

Horses in Cyberspace. Florida Natural History Museum. Well illustrated and nontechnical summary of the fossil evidence for horse evolution; its not as straightforward as some people think.

Horse Evolution. Kathleen Hunt, Talk Origins Archive. Comprehensive, slightly technical summary of the fossil evidence for horse evolution with a historical background, time scale, and discussion of major equine lineages.

The Evolution of Horses. George Johnson. Textwriter, Inc., Washington University. Good short summaries of the main physical changes that accompanied horse evolution; increasing size, toe reduction, and changes in tooth structure.

Whales:

Primitive Whales and Whale Evolution. Enchanted Learning Software. Nontechnical summary of the evolution of whales that lists important species in the evolution of whales from land mammals.

Becoming Whales. Evolution and the Nature of Science Institute. Lesson plan in which students arrange pictures of ancient whales to determine the order of evolution. This lesson provides multiple independent lines of evidence to show that there is gradual accumulation of changes, linking certain terrestrial mammal groups with modern whales.

Evolution of Whales. National Geographic. Excerpt from article with several pictures of important fossils, which indicate that whales evolved from land mammals. A text description of the evidence for the evolution of land animals into whales is provided at Ancient Walking Whales.

Elephants:

Stories and Histories--Evolution. Elephant Information Repository. Short evolutionary history of elephants with a simplified phylogenetic diagram.

Elephant Evolution. Allelephant.com. Easy-to-understand summary of elephant origins, including a description of how fossil elephant and elephant ancestors are identified, and classified with line drawings of the major groups.

Also see:

Evolution key links. Earth Science Education Network, Kentucky Geological Survey. Selected and annotated links that explain the theory of evolution.
