The Malayan Papilionidæ or Swallow-tailed Butterflies, as Illustrative of the Theory of Natural Selection

Focusing on the evidence for natural selection, this work by Alfred Russel Wallace explores the Malayan Swallow-tailed Butterflies as a case study. Wallace, inspired by contemporary naturalists, embarked on a significant exploration in the Amazon rainforest, where he meticulously documented various aspects of the environment and its inhabitants. His experiences led him to refine his evolutionary theories, culminating in a pivotal 1858 article shared with Charles Darwin. This publication highlights Wallace's crucial role in the evolution of natural science and evolutionary theory.
