Final answer:
Alfred Wallace collaborated with Charles Darwin to present papers on natural selection to the Linnean Society in 1858, bolstering Darwin's later work in 'On the Origin of Species'.
Step-by-step explanation:
The individual who collaborated with Charles Darwin on the Linnean Society paper was Alfred Wallace. In 1858, both Darwin and Wallace presented scientific papers on the concept of natural selection before the Linnean Society in London. Their simultaneous presentation is particularly notable because Wallace's paper on evolution helped to confirm Darwin's ideas, which were later fully elaborated in Darwin's landmark publication, On the Origin of Species, in 1859. The collaboration between Darwin and Wallace stands as a pivotal moment in the history of biology, reaffirming significant scientific contributions to our understanding of evolution.
