"The Selfish Genius" has been criticized in "The Economist" for failing to fully understand Dawkins' selfish gene metaphor, with the reviewer claiming Dawkins accommodates proposed alternative evolutionary mechanism Elsdon-Baker suggests within her own ideas. However a generally positive reception has been seen amongst proponents of group selection and Philip Ball wrote a largely positive review in "The Times" that acknowledges she is right to "call time on a Whiggish view of the history of evolution". "Popular Science" author Brian Clegg reviewed the book and described it
