Let’s go meta. Recently, ecologist extraordinaire Dr. Jacquelyn Gill (or is it Professor cos of that weird American system?) wrote a wonderful review article on the extinctions that affected many large mammal species during the last 50-10,000 years. This period is known as the Quaternary, and was a time when ice ages were running rife between warmer periods, and herds of enigmatic mammals roamed the steppes. It’s also a time when many wonderful animals, such as mammoths, disappeared from our planet forever, apart from rare fuzzy sightings from drunk Russians that later turn out to be a bear, or nothing. The result is that although we have a spectacular range of mammals decorating our landscapes today, this is but a shadow of mammals’ true splendour back just a few thousand years.
