the ground rules for the biota (Court Jester hypotheses). . . . A class of alternative ideas, here termed Court Jester hypotheses, share the basic tenet that changes in the physical environment rather than biotic interactions themselves are the initiators of major changes in organisms and ecosystems. . . . Court Jester hypotheses imply that events random in respect to the biota occasionally change the rules on the biotic playing field. Accelerated biotic response (relative to background rates) is the result."

The 2001 paper by Barnosky that is one of the first to use the term appropriate for the Court Jester side of the debate: the Stability hypothesis of Stenseth and Maynard Smith (1984), Vrba's Habitat Theory (1992), Vrba's Turn-over pulse hypothesis (1985), Vrba's Traffic light hypothesis and Relay Model (1995), Gould's Tiers of Time (1985), Brett and Baird's Coordinated Stasis (1995), and Graham and Lundelius' Coevolutionary Disequilibrium (1984) theories.

730:"Indeed, as Ned Johnson remarked (after listening to a lecture expressing these ideas), ‘‘Maybe it is time for the Court Jester to marry the Red Queen.’’ That is, perhaps the dichotomy between the two hypotheses is really a dichotomy of scale, and that as we look for ways to travel across biological levels, we will find ways to resolve the dichotomies."

in 1999 in allusion to the Red Queen hypothesis. In a 2001 paper on the subject, Barnosky uses the term without citation, suggesting that he is the one who coined it. Westfall and Millar attribute the term to him (citing the 2001 paper) in a paper of their own from 2004. Michael Benton also credits

The Red Queen hypothesis (focusing on evolution by biotic interactions) and Court Jester hypothesis (focusing on evolution by abiotic factors such as stochastic environmental perturbations) both influence coevolutionary switching in host-parasite interaction. Barnosky acknowledges in the 2001 paper
753:. It refers in evolution theory to the arms race of evolutionary developments and counter-developments that cause co-evolving species to mutually drive each other to adapt. There is dispute over how strongly evolution at the scale of speciation is driven by these competitions between
