Both failed to understand the mechanism of inheritance. Darwin had a mistake " blending " idea and Wallace seemed to go along with this concept, though inheritance is particulate.
Very closely in natural selection, but in some drivers of evolution, such as sexual selection, Wallace and Darwin disagreed on the fine points. Wallace could not accept female choice in sexual selection when Darwin posited this concept. Lively exchanges in letters were held over this disagreement.
That species arose by mean of natural selection. The independently come up with a theory of evolution by natural selection in 1858.
Darwin was prompted to publish his theory of evolution by Alfred Russel Wallace. Wallace sent Darwin a manuscript outlining a similar theory of natural selection based on his own research, prompting Darwin to expedite the publication of his own work.
Alfred Russel Wallace is credited as the co-discoverer of the theory of natural selection alongside Charles Darwin. Wallace independently formulated the theory while working in Southeast Asia, sending his findings to Darwin in 1858, prompting the publication of the joint paper "On the Tendency of Species to Form Varieties" in 1858.
That selection was natural.
The scientist Alfred Russel Wallace actually studied the idea of natural selection before Charles Darwin. Wallace and Darwin later became research colleagues, but Darwin became more well known after publishing "The Origin of Species".
Alfred Russel Wallace independently developed ideas of natural selection around the same time as Charles Darwin. In 1858, both Wallace and Darwin jointly presented their findings on evolution and natural selection, leading to the publication of Darwin's "On the Origin of Species" in 1859.
Alfred Russel Wallace, a contemporary of Charles Darwin, independently proposed a theory of evolution by natural selection that was similar to Darwin's. Wallace's work on natural selection prompted Darwin to publish his own views on the subject. The two scientists jointly presented their work in a paper in 1858.
