I came to this book looking for a definitive account of human evolution, I didn't quite get what I was looking for, but I'm more than satisfied.
I've been looking for a book such as this because I've found that, at times, the usage of names differs so much author to author (Erectus, Ergaster, etc.) that it can get very confusing. This book seemed just the ticket as the author is the leading expert on human origins at the Natural History Museum in London and it shows: he has a dizzying command of his subject area.
The blurb on the inside cover says that he will answer all of the big questions in the debate on our origins. So, does he? As you might expect the answer is yes and no.
Yes, because many, or most, of the issues that you would want a book like this to deal with are discussed in detail: what kind of relationship existed between modern humans and the Neanderthals, where & when the first modern humans appeared, what the genetic evidence says about us, whether the Neanderthals and other hominins are actually cousins or ancestors of ours, and so on.
No, because some issues are not dealt with: the book does not really discuss species previous to Homo Erectus, so there's little or nothing about our common ancestor with chimpanzees, or the australopithecines, Homo habilis, etc. Instead, the focus is on the later hominins: Erectus, Heidelbergensis, the Neanderthals and us, especially the last two. So, roughly, the book covers the last two million years, but most especially the last few hundred thousand. This is fair enough - there are no superfluous sections in this book, and so discussing these species would have meant a lot more pages and taken the author away from his goal of identifying and describing the origin of our species specifically, rather than the whole Homo genus. But I didn't know this before I bought the book. Also no, because one question, which seems to me to be a central one, was dealt with only briefly over the course of four or five pages: the evolution of language. You might think this is because there's not much to be said - there aren't any fossils of words - but this is a whole area of study, so this was a slight disappointment.
Whether you like this book or not will also depend on what kind of book you usually read. If you have only a passing interest in evolution and science in general, but you find this issue appealing, I think you may find chapters 2 and 3 of this book hard going. These sections mainly focus on how experts in the field can date and extract information from the fossils they find; so, while these issues are relevant to the matter in hand, they concern the scientific method rather than the history and evolution of mankind. It's not overly technical, but there is a lot of information, mixed in with a little of bit of the author's own biography. I found it very interesting, but I did think that the author was brave to place so much of this material so early in the book.
On the other hand, if you're a scientist or you regularly read books on scientific subjects, I confidently predict you will lap this up. It covers a lot of ground authoritatively and, if you're the kind of person who, like me, reads books on issues which human evolution has some bearing on, I think you will often come back to this book for reference. It's well written, there's a bit of humour in there occasionally, and while the author is keen to put across his point of view - that we have a recent African origin - I think he deals with other opinions very fairly.
Highly recommended. If you like that kind of thing.
