This book presents orthogenesis as a guiding force in evolution, arguing that natural selection alone cannot explain how species originate or change. It outlines a set of laws the author says govern evolution and shows how these principles apply to living creatures, including butterflies.

In addition to theory, the work discusses how species form and how similar traits can emerge through development, not just selection. It challenges widely held views and offers a different lens for understanding the diversity of life.

Understand the claims for definite, directed evolution and the role of organic growth.
See how the author connects laws of transformation to real-world examples in butterflies.
Learn why the author argues that selection is not the primary engine of transmutation.
Explore how mimicry and species formation might arise from developmental tendencies.

Ideal for readers curious about alternative theories in evolutionary biology and the history of scientific debate.

Store Description

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 visit 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. We are a company who put our customers at the centre of everything we do as we understand the importance of reading because once you learn to read, you will forever be free. There are a whole lot of things in this world of ours that we are yet to explore, which is why we will forever inspire curious minds.
