I read this book in the early 1960’s soon after it was published. I have wanted to re-read it for many years to find out if it is as funny as I remembered it to be. The only problem was I could not remember the name of the author. Now, of course, I only have to type the title into a search engine to find out that it was written by Roy Lewis. Apparently, it was his only book. He died in 1996 having become something of a cult in translation in French and Italian. The Evolution Man is now available in English after being out of print for many years.
The story concerns a family of ape-men living in Uganda in the Pleistocene period. At the start of the book they discover how to harness fire but it is some time before they learn to cook. They suffer from chronic indigestion because they have to chew raw meat for eight hours a day. This chewing gives them plenty of time for speculation as to whether they are mid-, late- or, heaven forbid, early-Pleistocene. They learn the joys of exogamy in order to speed up the evolutionary process and by the end of the book they are beginning to develop religious theories.
I imagine that this book predates the Flintstones but, in common with the cartoon series, its humour is based on anachronism. But there are no dinosaurs in this book; as far as I can tell the science seems to be accurate, the humour coming from the anthropological and archaeological insight that the ape-men have into their situation. And is it as funny as I remembered it to be? Every bit.
