Title: Introducing Evolution

Author: Dylan Evans & Howard Selina

Publisher: Icon Books, London

Year published: 2010

176 pages

Introducing Evolution provides a concise yet thorough exploration of the central pillars of biological thought. The book begins by situating Charles Darwin in his historical context, explaining how his voyage on the HMS Beagle and his observations of finches and tortoises in the Galapagos led to his groundbreaking theory. It clarifies that Darwin was not the first to propose that species change over time, but he was the first to provide a viable mechanism: natural selection.

The narrative explains how individuals with advantageous traits are more likely to survive and reproduce, passing those traits to the next generation. A significant portion of the text addresses the missing link in Darwin's original work, which was the lack of a mechanism for inheritance. This gap was eventually filled by the integration of Mendelian genetics, leading to the modern synthesis. The authors guide the reader through the discovery of DNA and how mutations provide the raw material for evolution by introducing genetic variety.

Beyond the mechanics of biology, the book delves into the evidence supporting evolutionary theory, ranging from the fossil record and comparative anatomy to molecular biology. It also touches upon controversial extensions of the theory, such as sociobiology and evolutionary psychology, which attempt to explain human behavior and social structures through the lens of adaptive survival.

The authors maintain a neutral, educational tone, addressing common misconceptions and the ongoing dialogue between science and religion. They emphasize that evolution is not a ladder toward perfection but a branching tree of life, where adaptation is always relative to a specific and changing environment. By the end, the book reinforces that evolution is the unifying principle of biology, essential for understanding everything from antibiotic resistance to the history of humanity itself.

The grotesque comedy of human existence

  Title: Echo's Bones Author: Samuel Beckett Publisher: Faber & Faber, London Year published: 2014 121 pages Echo's Bones is a short story first written in 1933 and only published decades later.  It was intended as an additional tale to Beckett’s collection More Pricks Than Kicks but was initially rejected for being too strange and unsettling. The story follows Belacqua Shuah , Beckett’s recurring anti-hero, who has already died in the earlier collection.  In Echo's Bones, he is resurrected and wanders through surreal and bizarre encounters that mix death, sexuality, and absurd humor .  The narrative unfolds in a fragmented, dreamlike style filled with puns, mythological allusions , and grotesque imagery. The text reflects Beckett’s early experimentation with themes that would define his later work: the futility of existence , the absurdity of human desire , and the blending of comedy with despair.  It is both difficult and playful, showing the seeds of his ...

Defining the warrior spirit

  Title: The Way of the Warrior Author: Jõtarõ Publisher: Citadel Press, New York Year published: 2011 207 pages The book is a reflective and meditative exploration of the mindset, ethics, and spiritual discipline required to walk the path of a true warrior .  Rooted in the traditions of the Japanese samurai and inspired by Zen philosophy , the book delves into the timeless virtues that define the warrior spirit— honor, loyalty, courage, discipline, humility, and self-awareness . Rather than focusing solely on the physical aspects of battle, Jōtarō presents the warrior's path as a lifelong journey of inner development.  The warrior is not merely one who wields a sword, but someone who masters the self, upholds moral principles, and stands firm in the face of adversity.  The text teaches that the battlefield exists as much within as it does outside; every challenge, fear, and emotion must be confronted with clarity and resolve. Central to the book is the idea that a ...
