Darwin and Wallace

• Evolution is the change of inherited characteristics within a population over time through natural selection, which may result in the formation of a new species
• Alfred Russel Wallace was a great admirer of Darwin and a fellow naturalist who independently proposed the theory of evolution by natural selection
• Wallace produced scientific journals with Darwin in 1858, which prompted Darwin to publish On the Origin of Species the following year
• Wallace worked around the world gathering evidence to support his evolutionary theory
• Wallace is best known for studying warning colouration in animals and his theory of speciation
• Speciation is the formation of new and distinct species in the course of evolution
• Wallace proposed a theory of evolution that matched Darwin's unpublished ideas, which encouraged Darwin to collect his scientific ideas and collaborate with Wallace
• Darwin and Wallace published their scientific ideas jointly in 1858
