On the Tendency of Varieties to Depart Indefinitely From the Original Type

Focusing on evolutionary theory, this work by Alfred Russel Wallace explores the concept of variation among species. Inspired by naturalists, Wallace embarked on a journey in the Amazon rainforest, where he meticulously documented his observations of its diverse ecology and cultures. His experiences shaped his ideas on natural selection, culminating in a groundbreaking article shared with Charles Darwin in 1858. This republished piece highlights Wallace's significant contributions to natural sciences and his role in shaping evolutionary thought.
