Niles Eldredge
Quick Summary
Niles Eldredge is an American paleontologist known for co-developing the theory of punctuated equilibrium with Stephen Jay Gould in 1972. This theory proposes that evolutionary change occurs in rapid bursts, rather than at a slow, constant rate. These bursts of speciation are followed by long periods where organisms experience little change, a concept known as stasis. Eldredge's work emphasizes the importance of paleontology in understanding large-scale evolutionary patterns, suggesting that population genetics alone is insufficient for explaining these long-term changes.12

With Niles Eldredge, he developed in 1972 the theory of punctuated equilibrium, a revision of Darwinian theory proposing that the creation of new species through evolutionary change occurs not at slow, constant rates over millions of years but rather in rapid bursts over periods as short…
