The idea of natural selection as the fundamental process of evolutionary changes was reached
- By Alfred Russell Wallace in 1901
- Independently by Charles Darwin and Alfred Russell Wallace in 1859
- Independently by Charles Darwin and Alfred Russell Wallace in 1900
- By Charles Darwin in 1866
The correct answer is: Independently by Charles Darwin and Alfred Russell Wallace in 1859
In 1831, Charles Darwin accepted an unpaid post of naturalist on the surveyship HMS Beagle, which spends the five years at the sea charting the east coast of South America and gave theory of natural selection. Alfred Russell Wallace had travelled widely in South America, Malaya and the Eastern Indian archipelago and come to the same conclusions as Darwin regarding natural selection.
In 1858, Wallace wrote an essay, outline his theory and sent it to Darwin. This stimulated and encouraged Darwin and in July 1858, Darwin and Wallace presented papers on their ideas at a meeting of the Linnean Society in London. Over a year later, in 1859, Darwin published
‘On the origin of species by means of natural selection’.
