Such discoveries are often a multi-step, multi-person process. Multiple discovery sometimes occurs when multiple research groups discover the same phenomenon at about the same time, and scientific priority is often disputed. The listings below include some of the most significant people and ideas by date of publication or experiment.

January 10 – John Gould reports to the Zoological Society of London that bird specimens brought by Charles Darwin from the Galápagos Islands which Darwin had thought were blackbirds, "gross-bills" and finches are in fact "a series of ground Finches which are so peculiar" as to form "an entirely new group, containing 12 species", an important step in the inception of Darwin's theory.
