What was Stephen Jay Gould theory?
Gould’s most significant contribution to evolutionary biology was the theory of punctuated equilibrium developed with Niles Eldredge in 1972.

What did Jay Gould invent?

What did Gould and Eldredge contribute to the evolutionary theory?
In the 1970s, Gould and his colleague Niles Eldredge developed the theory of punctuated equilibrium. At the time, most biologists held that new species evolved from other species by the small gradual changes continuously accumulated by natural selection over millions of years.
How does punctuated equilibrium relate to evolution?
“Punctuated equilibrium is the idea that evolution occurs in spurts instead of following the slow, but steady path that Darwin suggested. Long periods of stasis with little activity in terms of extinctions or emergence of new species are interrupted by intermittent bursts of activity.”
