Ian Tattersall (born 1945) is a British-born American paleoanthropologist and a curator emeritus with the American Museum of Natural History in New York City, New York. In addition to human evolution, Tattersall has worked extensively with lemurs. Tattersall is currently working with The Templeton Foundation.

Tattersall was born in 1945 in the United Kingdom, and grew up in eastern Africa. He trained in archaeology and anthropology at the University of Cambridge, and earned his PhD from Yale University in 1971.

Tattersall has concentrated his research over the past quarter-century on the analysis of the human fossil record and the study of the ecology and systematics of the lemurs of Madagascar, and is considered a leader in both areas.

Tattersall believed that existing literature was not an adequate resource for comparing human fossils because of the many terminological variations. As a result, Tattersall and research associate Jeffrey Schwartz set out to document major fossils in the human fossil record. Their resulting three-volume work, Human Fossil Record, employs a consistent descriptive and photographic protocol, thus making it possible for individuals to make necessary fossil comparisons without the extensive travel that was once needed to consult original fossil findings.

Tattersall maintains that the notion of human evolution as a linear trudge from primitivism to perfection is incorrect. Whereas the Darwinian approach to evolution may be viewed as a fine-tuning of characteristics guided by natural selection, Tattersall takes a more generalist view. Tattersall claims that individual organisms are mind-bogglingly complex and integrated mechanisms; they succeed or fail as the sum of their parts, and not because of a particular characteristic. In terms of human evolution, Tattersall believes the process was more a matter of evolutionary experimentation in which a new species entered the environment, competed with other life forms, and either succeeded, failed, or became extinct within that environment: "To put it in perspective, consider the fact that the history of diversity and competition among human species began some five million years ago when there were at least four different human species living on the same landscape. Yet as a result of evolutionary experimentation, only one species has prospered and survived. One human species is now the only twig on what was once a big branching bush of different species." This idea differs from the typical view that homo sapiens is the pinnacle of an evolutionary ladder that humanity's ancestors laboriously climbed.
