Description Do you think your relatives are revolting? Well, never mind your wrinkly gran and your embarrassing aunts and uncles. In this book, you’ll meet some revolting relatives you never knew you had – the slimy life forms that crawled out of the primordial sludge of the Earth’s ancient seas! We can trace all living things on earth back to those squishy creatures – but why are we still here when other creatures have vanished forever? It’s because we learned to evolve – or die!
