Whether or not we know it, the sixth global extinction is already under way, propelled not by a meteor but by human activity on Earth. Take a long step forward into the year 4847 with the help of stunning pop-ups portraying eight fantastical creatures, along with spreads and flaps presenting details about each one. Paper engineer Shawn Sheehy envisions the aftermath of extinction as a flourishing ecosystem centered around fictional creatures that could evolve from existing organisms. Promising high appeal for science-fiction fans of all ages -- and plenty of food for discussion -- this evolutionary extravaganza offers a time line of the six extinction events in Earth's history, a "field guide" to each creature, a diagram of species relationships, a habitat map of the (imagined) ruins of Chicago, and an illuminating author's note.
