New species of organisms may emerge if a.) an individual organism makes sudden dietary changes. b.)naturally occurring selective pressures favor new traits. c.)humans create new environmental conditions. d.) two diverse species naturally interbreed. e.)a mutation results in a fatal condition.

According to the theory of punctuated equilibrium, at what rate does speciation occur? species change depending on the rate of natural selection. after periods of stasis, new species evolve relatively rapidly. species change slowly and eventually form new species. some species change quickly and others change slowly to balance the overall rate.
