Mammoth kill: did humans hunt giant mammals to extinction? Or give them lethal disease?

Article Abstract:

Three competing models for explaining the mass extinction of giant mammals in North America are detailed. The overkill theory, offered by John Alroy of the University of California Santa Barbara, proposes that an expanding population of human hunter-gatherers were responsible. Ross MacPhee, American Museum of Natural History mammologist, believes that humans are indirectly responsible, by introducing disease into the animal population. Severe climatic fluctations are posited as the cause by Russell Graham of the Denver Museum of Nature and Science.

The mammals of island Europe

Article Abstract:

Illustrations of animal fossils found in Messel, Germany that date back to the Eocene period have been created to better determine what the animals looked like. Comparisons with other excavated fossils suggest that Europe was once an island, due to physical differences between the fossils.
