It seems obvious that a pig will never give birth to a puppy, but why should that be the case? Variation in Living Things explains the causes and limits of variation in species - such as blood groups and disposition to disease - and why it is so important to their survival. It tackles common confusions about the science and shows how topics are relevant to the reader.
