The concept of punctuated equilibrium was, to some, a radical new idea when it was first proposed by Stephen Jay Gould and Niles Eldredge in 1972. Now it is widely recognized as a useful model for one ...

Is evolution like a well-tuned car that purrs down the road at a steady pace? Or is it more like an aging, rattling jalopy that often lurches forward? The aging jalopy is a handy metaphor for the ...

History is often shaped by moments of profound change—inflection points that redefine what’s possible, much like cosmic asteroids that strike the planet and alter the course of evolution. Today, we ...

A ubiquitous mantra of today can be captured in one word—"innovate." From business leaders to homemakers to athletes, the need to innovate and serve the “I want it when I want it” demon seems to know ...

Over the past 500 million years, nearly all evolutionary changes in octopuses and squids occurred in rapid bursts during the emergence of new species, according to research from the University of ...

What does an esoteric concept in evolutionary biology have to do with the speed of change we are seeing in the workplace, retail and entertainment? Punctuated equilibrium is a theory that evolutionary ...

In evolutionary biology, the theory of punctuated equilibiria states that evolution is not a gradual process but instead consists of long periods of stasis interrupted by rapid, catastrophic change.

This refers to a theory in evolutionary biology which states that the origin of a new species is usually an abrupt process that cannot always be fully traced by scientists. It is generally used to ...
