Our Human Story

Great book, very informative and interesting

As the late evolutionary theorist Stephen Jay Gould constantly used to reiterate, the evolutionary history of life is not a ladder of progress, but rather a bush or tree with many different branches.The authors of this very interesting and well-illustrated book show how true this is of human evolution. The hominin family tree is a very complicated mass of branches, beginning about seven million years ago when the hominin lineage split from the chimpanzee lineage.For most of that seven million years there has been a great diversity of hominin species, with several existing at the same time. For example, over the last two million years there have been at least ten different species of the Homo genus. And a lot is still not known: with future discoveries and DNA research, the tree will almost certainly get bushier.Only for the last 40,000 years or so has our own species, Homo sapiens, which first appeared over 200,000 years ago, been the sole surviving hominin species.The problem is, as the authors show, that it is often difficult to know exactly what the relationships are between the various branches. For example, it is difficult to know whether a particular species is an ancestor of ours, or whether it belongs to a different side branch of the hominin tree. The result of this is that there are many disagreements among scientists about how to classify various fossils and about their evolutionary relationships.What is clear is that upright stance developed long before the appearance of the large brain. Bipedalism came soon after the divergence of the hominin and chimpanzee lineages seven million years ago. The large brain came much later, leading to the intelligence, flexible behaviour, consciousness and art that we associate with humans. The large brain probably developed due to a combination of interacting factors: meat-eating, complex tool-making, social interaction and language. (My bet is that tool-making started off this feedback loop and that the previous development of bipedalism was important in that it had freed up the hands for the later development of complex tool-making.)Other primates and some birds can make and use simple tools, and some pre-Homo hominins (Australopiths) might have done the same. But humans in the Homo genus took tool-making to a quantitatively and hence qualitatively different level.As the authors mention, some scientists have in the past claimed that in the history of our own species (Homo sapiens) there was a “creative explosion” in Europe about 40,000 years ago (with the appearance of cave art etc), long after the appearance of the species itself over 200,000 years ago. They claimed that this “Great Leap Forward”/ “Human Revolution”/”Big Bang” was caused by some biological change to the brain, possibly linked to the development of language.But this idea of some (invisible and unprovable!) biological change to the brain about 40,000 years ago has been shot down in recent years by the discovery of evidence for art and sophisticated tools dating from much earlier than the time that the “Great Leap Forward” is supposed to have happened. For example, engraved pieces of ochre have been found in Africa dating from 75,000 years ago, and decorative beads have been found, again in Africa, dating back 100,000 years.As Stephen Oppenheimer has argued, language developed much earlier than 40,000 years ago and “...humans came out of Africa already painting.” There may even have been language and creativity in earlier species. For example, there is now evidence for Neanderthal art and possibly ritual burial; and there is also evidence that the Neanderthals could have vocalised in a similar way to Homo sapiens.In any case, the “creative explosion” theory wrongly assumes that behavioural change must be determined by biological change. But why does cultural change have to imply a change to the brain? It is more likely that the brain had become “modern” when Homo sapiens first evolved in Africa 200,000 or more years ago, and that any later cultural change took place for non-biological reasons. After all, the development of farming 12,000 years ago, of cities and writing 5,000 years ago, and of industry 200 years ago were also “Great Leaps Forward”, but no one believes that these were the result of genetic changes to the human brain.The final point I want to mention is that the authors refer to possible evidence of social stratification 35,000 years ago, in the form of some burials having grave goods which would have taken a lot of time to create. But, if this is so, it would surely just have been a case of respected (or at most, slightly privileged) individuals, because most evidence suggests that hunter-gatherer societies were egalitarian. Fully-fledged class differences did not appear until about 5,000 years ago, when, following the development of agriculture, “civilisations” developed in which a ruling class managed to grab the surplus created by the labouring farmers.Overall, an excellent book. Highly recommended.Phil Webster.

I've been fascinated by "Early Man" (Neanderthals in particular and the pictures by Burian), since a schoolboy in the 1960s. My knowledge since has been dependent on the works (1967;1973 & 1997) of prof. (Harvard), William W. White and I felt I needed to read something "up to date". This book has not disappointed; it is clear, concise (154 pages) and updated to 2022; with information about Denisovans, etc.. It's inspired me to purchase "Britain: One million Years of the Human Story", also published by the Natural History Museum.

I am becoming more interested in our human history and this is the second book I have read about it - the first being Britain - One Million Years of the Human Story. I did not realise that we originally co-existed with so many other human species. All this was explained very clearly and was fascinating reading. I am in my 70s and this was not touched upon when I was at school. I hope that it is now.

First the negative, a few pages were incorrectly printed, but that did not detract from the wealth of information in this book, all amply illustrated with gorgeous photographs and easy to understand diagrams. My main takeaway was that around 150,000 years ago several species of humans coexisted and interbred, evidenced by modern day dna history testing.Sure there are many assumptions and speculations the further back in time you go, but that is to be expected.

I've always been interested in human evolution and this book explains what is known and doesn't second guess any of the clues. Theories are explained but care is taken not to treat them as fact. Excellent book, well worth reading.

This book was an excellent read.So informative and insightful.I highly recommend this book.I'm actually sad I've finished it.

A terrific volume which has succinct explanations and emphasises the evidence. Delivered extremely promptly.

Very in-depth

The book received in bad condition. Corner is bent. Disappointed with the packing.

This book is simple, straighforward and fairly comprehensive. It is good for catching up on human ancestry if one is embedded in another field.

I myself have often had difficulties to explain to interested non-scientists the complex history of the evolution of humans. Beginning from the first hominins to todays Homo sapiens. Or at least what we know about it and the many dicoveries with the tools of genetics over the last decades. Chris has achieved what many authors writing on this subject have not accomplished - a clear presentation of the tortuous pathway that lead to us in the end!

I've read several recent overviews of human fossil origins/ palaeo anthropology, and this I found is the best.Is the most up to date with regards to most recent thinking (2020), and models of human evolution with the latest fossil finds (including several in South Africa (Naledi, etc), and Flores's homo florensis etc as well as various genetic studies etc. Highlights how there is still a conundrum and debate right around the time of homo habilis, where the genus homo first branches away from the two genus of Australopithecines, and what exactly constitutes homo (the only one that has survived), which hasn't gone away for decades.Best, well illustrated, and most up to date on human fossil origins.
