The study of sasquatches inevitably leads to the study of archaic human ancestors. Humans and sasquatches share a common ancestor somewhere on the family tree, so it only makes sense to look closely at where we came from to learn about what sasquatches actually are. Below are books that I can recommend that might shed light on the sasquatch mystery in the context of paleoanthropology.
Masters of the Planet: The Search for Our Human Origins
by Ian Tattersall
Masters of the Planet: The Search for Our Human Origins is an excellent book granting insights into the extraordinary finds of paleoanthropology over the years. Of particular interest in this tome is the attempt to answer the age-old question of what makes us “human?” Once it was tool use, but that simple assumption no longer holds water, as is detailed in this book. Perhaps language, then? Well, not quite. Tattersall eventually answers his own question with “symbolic thought,” and then proceeds to show when that uniquely human trait arose in human ancestors. For bigfooters, this is a very interesting question. How “human” are bigfoots? How “bigfooty” are humans? This book, in its deep exploration of human ancestors (particularly the Australopithicines) is a fascinating read that points to some possible answers.
This book is an excellent overview of the history of paleoanthropology from the times of ancient Greece to the present. It details the dominant paradigms in the science, how they changed and became obsolete, and the discoveries that made the changes happen. Many of the major players in the field are discussed in context of their contributions. For a full review of the book, click this link.
