The Basis of a Theory of Organic Development" delves into a foundational debate within the field of biology: the age-old question of preformation versus epigenesis.

A crucial text for anyone interested in the history of science, "The Biological Problem of To-day" presents a clear exposition of the biological questions that spurred decades of research and laid the groundwork for modern genetic studies.
