Darwin, Huxley and the Natural Sciences not only explores evolutionary theory, botany, geology and zoology, but also the historical understanding of the physical world, religion, politics, philosophy and the dawning of the terms "survival of the fittest" and "social Darwinism."

This collection is made up of three principal parts:

• The Thomas Henry Huxley manuscript archive including his scientific papers, diaries and correspondence
• The Charles Darwin manuscript archive including the original manuscript versions of the "Origin of the Species," "The Movements and Habits of Climbing Plants," "The Descent of Man" and the HMS Beagle notebooks, but excluding Darwin's correspondence which is the subject of a separate printed edition
• The Charles Darwin Abstract and Offprint collection (contemporary articles annotated and arranged by Darwin to aid his own research)

These sources were compiled from collections originally dispersed at Imperial College, London, the University Library, Cambridge, and Down House, Kent. Taken together they provide a fundamental research and teaching collection for those working in the natural sciences, the history of science, scientific theory and all concerned with the evolutionary debate.
