4.6.3.2 Speciation (biology only)

Content	Key opportunities for skills development
$Students should be able to: describe the work of Darwin and Wallace in the development of the theory of evolution by natural selection explain the impact of these ideas on biology. Alfred Russel Wallace independently proposed the theory of evolution by natural selection. He published joint writings with Darwin in 1858 which prompted Darwin to publish On the Origin of Species (1859) the following year. Wallace worked worldwide gathering evidence for evolutionary theory. He is best known for his work on warning colouration in animals and his theory of speciation. Alfred Wallace did much pioneering work on speciation but more evidence over time has led to our current understanding of the theory of speciation. Students should be able to describe the steps which give rise to new species.$	$There are links with this content to Evolution. WS 1.1 The theory of speciation has developed over time.$
