Michael Powell's Washington PostÂ review of the new Darwin exhibition at New York's American Museum of Natural History is generally praiseworthy butÂ Darwinists won't like his singing offÂ key late in the piece: "...in its eagerness to declare the grand evolutionary questions settled, the show takes its lone stumble. Only four decades ago, most paleontologists rejected theÂ theory, now broadly accepted, that comets and volcanic eruptions delivered mass extinctions and so played a key role in speeding evolution. Nor are scientists clear on the mechanism by which one species evolves into another; curator Eldredge and the late scientist Stephen Jay Gould crafted the once heretical theory of punctuated equilibrium, which holds that species sometimes evolve in grand leaps."
Then Powell notesÂ that oneÂ prominent scientist, Simon Conway Morris, is now arguing thatÂ "even very distant species share structural similarities and journey toward inevitable complexity. This suggests to himÂ that evolution adheres to an architecture."
