In Europe, many large animal species, such as mammoths, became extinct soon after humans first migrated to the animals' areas of habitation  The spread of such extinctions closely followed the pattern of human migration
However, since humans tended to migrate to areas as the climate in those areas began to warm, the extinctions might have been precipitated by the climatic warming rather than by human migration
Many animal species that became extinct in Europe survived longer in areas that were isolated from human populations but that experienced intense climatic warming.
