According to the punctuated equilibrium model, (a) populations slowly diverge from one another (b) the evolution of species occurs in spurts interspersed with long periods of stasis (c) evolutionary novelties originate from preadaptations (d) reproduc. tive isolating mechanisms restrict gene flow between species (e) the fossil record, being incomplete, does not accurately reflect evolution as it actually occurred
According to the punctuated equilibrium model, (a) populations slowly diverge from one another (b) the evolution of species occurs in spurts interspersed with long periods of stasis (c) evolutionary novelties originate from preadaptations (d) reproductive isolating mechanisms restrict gene flow between species (e) the fossil record, being incomplete, does not accurately reflect evolution as it actually occurred
The punctuated equilibrium hypothesis: a. recognizes that morphological evolution may occur slowly or quickly. b. suggests that major morphological novelties arise gradually. c. may help explain why there are so many “missing links” in the fossil record. d. suggests that the fossil record is usually complete. e. links mass extinctions to the impact of asteroids striking Earth.
