First Steps: How Walking Upright Made Us Human

The book is written so well, with clear explanation

This book is a fascinating look at the fossil record of how Homo sapiens became bipedal, and how bipedalism influenced our subsequent evolution, written by a paleoanthropologist who teaches human anatomy (among other subjects) at Dartmouth College. The book is also very well-written. My only criticism is that the publishers could have included more line-drawings to illustrate points made in the text. I am recommending this book to my friends, particularly those who spend a lot of time on their feet---running, hiking, walking, and dancing.

Me ha gustado recibir el producto al día siguiente. Lo uso para leer divulgación científica de calidad que ya no se traduce al castellano.

Really great book - straddles the line between 'pop-science' and 'academic science' really well. (Much more engaging, than say, 'Kindred' which I found a bit too technical and monotonous.) As well as the evolution side of things (with quite a few revelations) there's a good tangent towards the end where the author looks at the health benefits of walking and running.

古人類学者が霊長類・人類の化石の発掘から判明した二足歩行出現の歴史をわかりやすく解説していて興興味深くとても面白く読めました。また、二足歩行が、人類をお互いに助け合わなくては生き抜いていけない、社会的な動物にしたという最後の部分（出産、子育て、病気怪我の介護等々）にちょっと感動しました。

This is an interesting and well-written history of how we came to be the only ape who walks on two legs. The book also suggests that our bipedalism may have accounted for our ultimate dominance as a species. It is difficult to imagine that humans could have achieved our superiority without first freeing up our arms and hands for uses other than traveling from one place to another. This is an extremely accessible and understandable book for the non-scientist. I highly recommend it!
