Alfred Russel Wallace
Alfred Russel Wallace was a British naturalist, explorer, geographer, and biologist, best known for independently conceiving the theory of evolution through natural selection. His work on biogeography, particularly his identification of the Wallace Line, a boundary that separates the ecozones of Asia and Wallacea, significantly contributed to the field. Wallace's extensive travels in the Amazon Basin and the Malay Archipelago provided crucial data and insights that paralleled and complemented Charles Darwin's research.

The two first of the series are printed without alteration, because, having gained me the reputation of being an independent originator of the theory of “natural selection,” they may be...

CHAPTER XXI. THE MOLUCCAS—TERNATE. ON the morning of the 8th of January, 1858, I arrived at Ternate, the fourth of a row of fine conical volcanic islands which shirt the west coast of the large and almost unknown island of Gilolo.

CHAPTER I. EARLY OBSERVERS OF MARS. Few persons except astronomers fully realise that of all the planets of the Solar system the only one whose solid surface has been seen with certainty is Mars; and, very fortunately, that is also the only one which is sufficiently near to us for the physical features of the surface to be determined with any accuracy, even if we could see it in the other planets. Of...

CHAPTER I. PHYSICAL GEOGRAPHY. From a look at a globe or a map of the Eastern hemisphere, we shall perceive between Asia and Australia a number of large and small islands forming a connected group distinct from those great masses of land, and having little connection with either of them. Situated upon the Equator, and bathed by the tepid water of the great tropical oceans, this region enjoys a climate...
