These included the concept of warning colouration in animals, and the Wallace effect, a hypothesis on how natural selection could contribute to speciation by encouraging the development of barriers against hybridization. Wallace was one of the leading evolutionary thinkers of the 19th century and made a number of other contributions to the development of evolutionary theory besides being co-discoverer of natural selection. He was considered the 19th century's leading expert on the geographical distribution of animal species and is sometimes called the "father of biogeography". Wallace did extensive fieldwork, first in the Amazon River basin and then in the Malay Archipelago, where he identified the Wallace Line that divides Indonesia into two distinct parts, one in which animals closely related to those of Australia are common, and one in which the species are largely of Asian origin. He is best known for independently proposing a theory of natural selection which prompted Charles Darwin to publish his own theory. ![]() ![]() Throughout the book, Wallace also reflects on the impact of colonialism and the exploitation of natural resources in the region and offers insights into the social and cultural practices of the indigenous peoples he encountered.Īlfred Russel Wallace, OM, FRS was a British naturalist, explorer, geographer, anthropologist and biologist.

He provides detailed accounts of his adventures, including his encounters with orangutans, his travels along the rivers of Borneo, and his interactions with the indigenous peoples of the region.
