The extinction of an animal is part of the complex evolutionary process of life, with one species disappearing every 100 to 300 years. However, the past 500 years have seen the extinction of over 80 mammalian species. This new rhythm is directly linked to human activity, which has long impoverished our planet. Some of the species represented here were known for such a short period of time that they vanished without even leaving a trace. Others, like the dodo, have remained in our lives as a symbol of our capacity for annihilation, while some others may have never existed.
