Eldredge began his undergraduate studies in LatinatColumbia University. Before completing his degree he switched to the study of geology under Norman D. Newell. It was at this time that his work at the American Museum of Natural History began, under the combined Columbia University-American Museum graduate studies program.
In 1969, Eldredge became a curator in the Department of Invertebrates at the American Museum of Natural History, and subsequently a curator in the Invertebrate Paleontology section, a position from which he recently[when?] retired. He was also an adjunct professor at the City University of New York. His specialty was the evolution of mid-Paleozoic Phacopida trilobites, a group of extinct arthropods that lived between 543 and 245 million years ago.
Eldredge and Stephen Jay Gould proposed punctuated equilibria in 1972. Punctuated equilibrium is a refinement to evolutionary theory. It describes patterns of descent taking place in "fits and starts" separated by long periods of stability.
Eldredge went on to develop a hierarchical vision of evolutionary and ecological systems. Around this time, he became focused on the rapid destruction of many of the world's habitats and species. In his book Unfinished Synthesis (1985), he proposed an extended evolutionary synthesis.[7]
Throughout his career, he has used repeated patterns in the history of life to refine ideas on how the evolutionary process actually works. Eldredge is proponent of the importance of environment in explaining the patterns in evolution.
He has published more than 160 scientific articles, books, and reviews, including Reinventing Darwin, an examination of current controversies in evolutionary biology, and Dominion, a consideration of the ecological and evolutionary past, present, and future of Homo sapiens.

Eldredge possesses a chart of the historical development of cornets (the musical instruments), which he uses as a comparison with that of the development of trilobites. The differences between them are meant to highlight the failures of intelligent design by comparing a system that is definitely designed, with a system that is not designed.[citation needed]
