Evolutionists nowadays divide over whether gradual change (evolution by creeps, as its critics call it) or Gould’s “punctuated equilibrium” (evolution by jerks) is better as a general model, but the latter certainly seems to make most sense of Homo habilis’s disappearance. About 1.8 million years ago East Africa’s climate was getting drier and open savannas were replacing the forests where Homo habilis lived; and at just that point, new kinds of ape-men10 took Handy Man’s place.
