Explore the frontiers of evolution and genetics in a classic 1931 science journal. This issue gathers bold discussions and original reporting on how mutations arise, how mutation experiments were conducted, and what they reveal about the forces shaping life.

In these pages, readers encounter detailed accounts of early genetic experiments using Drosophila (fruit flies), explanations of mutation mechanisms, and the lasting questions scientists faced about evolution, geology, and the age of the world. The issue also includes debates and commentary that illuminate the era’s scientific and cultural context, offering a window into how researchers connected laboratory work with broader theories of life’s history.

In-depth explanation of mutation, genetics, and how X-rays can induce changes in organisms

Hands-on descriptions of experimental methods and observation in fruit fly studies

Editorials and debates about evolution, creation, and the relationship between science and faith

A snapshot of science communication and public education efforts in the early 20th century

Ideal for readers curious about the historical development of evolutionary science, genetics, and how scientists weighed evidence in a time of lively debate.

Store Description

**Please note our transit times are from the date of dispatch.** We first started out as ?The Paperback Exchange,? a chain of physical bookstores where we would part exchange your beloved books for new stories to transport you to faraway places. However, as shopping started to evolve to online shops and marketplaces, we bid our stores goodbye to become ?PBShop.? This transition has only allowed us to blossom as we now ship thousands of titles to book lovers across the globe. We pride ourselves in being a community of local book lovers which allows our passion and devotion to shine in everything we do. In 2020 we not only celebrated our 20th birthday but our 1st birthday as being completely employee owned after becoming an E.O.T in September 2019. We are proud to be different and embrace standing apart on a book mountain by working from a virtual inventory which allows us to provide thousands of books that may be difficult to get for your bookshelf or your studies. Working with a number of different suppliers allows us to explore other avenues such as puzzles, sheet music and even stationery so we really do have something for everyone. Life is about being versatile in all realms of existence. If this is your first purchase with us, or you are a returning customer, we would like to welcome you to the PBShop family, for there is no friend as loyal as a book.
