<para xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> This article provides an introduction to the Special Section on Darwinian Perspectives on Electronic Communication. It starts with a discussion of the motivation for the Special Section, followed by several sections written by the Guest Editor (Ned Kock) and the Guest Associate Editors (Donald Hantula, Stephen Hayne, Gad Saad, Peter Todd, and Richard Watson). In those sections, the Guest Editor and Associate Editors put forth several provocative ideas that hopefully will provide a roadmap for future inquiry in areas related to the main topic of the Special Section. Toward its end, this article provides a discussion on how biological theories of electronic communication can bridge the current gap between technological and social theories. The article concludes with an answer to an intriguing question: Are we as a species currently evolving to become better at using electronic communication technologies? </para>

Despite numerous sex differences found in spatial navigation, perception, and verbal abilities, the manner in which these differences manifest themselves in terms of online navigation has yet to be explored. We propose a unified framework based on evolutionary psychology and supported by recent findings in cognitive neuroscience for understanding sex differences in cognition and how they relate to online navigation and website preferences. The literature on sex differences in navigation, object location, spatial rotation, the perception of color, form, and movement, and verbal fluency is reviewed within the context of their evolutionary underpinnings. Based on these findings, specific website design recommendations are proposed. Results of a pilot study examining sex differences in web navigation provide evidence that utilizing an evolutionary approach can engender findings with significant implications for e-communication researchers and practitioners alike.
