His view of contingency was criticized by Simon Conway Morris in his 1998 book "The Crucible of Creation". Conway Morris stressed members of the Cambrian fauna that resemble modern taxa. He also argued that convergent evolution has a tendency to produce "similarities of organization" and that the forms of life are restricted and channelled. In his book "Life's Solution" (2003) Conway Morris argued that the appearance of human-like animals is also likely. Paleontologist Richard Fortey noted that prior to the release of "Wonderful Life", Conway Morris shared a similar thesis to Gould's, but after "Wonderful Life" Conway Morris revised his interpretation and adopted a more deterministic position on the history of life.
