In 2002, Massimo Pigliucci devoted part of his "" to refuting each point presented in "Icons of Evolution". Amongst the refutations Pigliucci noted several mistakes Wells made and outlined how Wells oversimplified some issues to the detriment of the subject. Pigliucci also wrote an article-length review in BioScience and concludes, "Wells, as much as he desperately tries to debunk what to him is the most crucial component of evolutionary theory, the history of human descent, is backed against the wall by his own knowledge of biology." In 2005, Pigliucci debated Wells on Uncommon Knowledge on broader issues of evolution and intelligent design.
