When did life first appear on Earth? How did humans evolve? How did giraffe’s necks get longer? Are humans now perfectly designed?My First Book of Evolution answers these and many more questions about evolution and how it works in a fun and entertaining way.Simple concepts such as what is a family tree, what is a species, what is a cell and more complex ideas of natural selection, adaptation, speciation and the inheritance of traits are explained clearly using imaginative and appealing charts, graphics and illustrations accompanied by simple, bite-size nuggets of explanatory text.
