About HBES

The Human Behavior and Evolution Society serves all those studying the evolution of human behavior. Scientific perspectives range from evolutionary psychology to evolutionary anthropology and cultural evolution. The society’s worldwide membership includes researchers from a range of disciplines in the social and biological sciences.

HBES hosts an annual conference that provides a forum exploring current research in the field. The conference offers invited plenary presentations from leading scientists.

The official journal of HBES is Evolution and Human Behavior, an interdisciplinary journal presenting research reports and theory in which evolutionary perspectives are brought to bear on the study of human behavior.


HBES was founded October 29, 1988 at the University of Michigan. Participants in a national conference on Evolution, Psychology and Psychiatry (sponsored by the University of Michigan Evolution and Human Behavior Program) voted to create the organization, decide on a name, elect the first officers, and create a constitution for the Society. The Society was formed to promote the exchange of ideas and research findings using evolutionary theory, including studies of animal behavior, to better understand human nature.

In order to create flexibility in the Bylaws and to avoid the need to frequently amend the Bylaws (a costly and cumbersome process for an incorporated organization) the Council will need to implement detailed policies and policy changes as Resolutions. The following proposed resolutions will be offered at the 2005 Council meeting. They all codify current practices, some of which were written into the old Bylaws. The six-year terms in the current Bylaws for the Treasurer, Secretary-Archivist, and Council members would likely not be accepted by the Department of Corporations, hence two year terms with Resolution 2005-1 to achieve the desired continuity in these offices. Since “mail” has come to be email for all practical purposes in the conduct of the Society, all references to paper mail have been removed from the Bylaws and Resolution 2005-2 is offered to codify current practice. Despite wording in the Bylaws, the Society has never formally audited its books. This would cost several thousand dollars and is not recommended until non-profits have annual budgets of a few million dollars. Nevertheless, the Council does need to supervise the Treasurer’s activities. Resolution 2005-3 corresponds to current practice.

HBES Resolution 2005-1 Multiple Terms of Office

Whereas the offices of Treasurer and Secretary-Archivist are difficult to fill with competent persons, and

Whereas continuity of service in these offices benefits the Society, and Whereas the Society also desires continuity on the Executive Council,

Therefore be it resolved that incumbents in these offices may, at the discretion of the Elections Committee, be run unopposed, but with provision made for a write-in candidate, for up to a total of three two-year terms. Members of the Council may not serve more than three terms in succession.

HBES Resolution 2005-2 Definition of “Mail”

Whereas communication by electronic mail is desirable for the purposes of contacting members, conducting the business of the Council, securing votes in elections, and conducting other business of the Society, and

Whereas electronic mail is sufficiently secure and difficult to forge for almost all purposes,

Therefore be it resolved that “mail” in the Bylaws of the Society may be interpreted as electronic mail. The Council may require special security requirements for membership votes and other sensitive communications at its discretion.

HBES Resolution 2005-3 Verification of Treasurer’s Report

Whereas the current budget of the Society is not sufficient to warrant a formal audit of its books, and

Whereas the accounts of the Society are rather simple, and

Whereas the largest and most complex part of the accounts are handled by a University bookkeeping office with adequate safeguards against abuse, and

Whereas the Society does need to verify that the Treasurer’s annual report is accurate and complete,

Therefore be it resolved that the Treasurer will deliver to the President for her/his inspection copies of all bank statements, university account summaries, tax returns and other documents necessary to verify the accuracy of the Treasurer’s report. At the discretion of the Council, these documents will be further reviewed for accuracy by other appropriate means.

HBES Resolution 2005-4 Budget Committee

Whereas the current income and capital of the Society are substantial and growing, and

Whereas the Society needs to expend some of its funds in new ways that enhance its services to members,

Therefore be it resolved that the Society after each two-year election cycle establish a Budget Committee to propose budgets to be passed at the Executive Council meetings in the subsequent two years. The Budget Committee shall consist of the President and Treasurer ex officio and shall have as many other Executive Council officers as members as the Council deems appropriate. The Council shall elect a chair of the Budget Committee.


Whereas the members of the Human Behavior and Evolution Society often conduct organized activities that further the Society’s goals of promoting the evolutionary study of humans, and

Whereas these activities include meetings on special topics of interest to members.

Therefore be it resolved that the Executive Council will entertain proposals from members to expend HBES funds in support of such meetings based on a well supported proposal and with a report from the Treasurer stating the budgetary impact of funding the proposal.

Therefore be it also resolved that such expenditures will be granted, after a consultation by email with all members, if approved by a majority vote of the executive council, with any members organizing or attending the meeting not voting.

Therefore be it also resolved that the Executive Council will circulate a call for proposals once per year with a submission deadline, through direct communication or by posting to the Society’s web site, at the discretion of the Treasurer, and that such proposals will subsequently be evaluated simultaneously by the Executive Council.

Whereas HBES has established The HBES Lifetime Career Award for Distinguished Scientific Contribution and The HBES Early Career Award for Distinguished Scientific Contribution, and

Whereas a regular procedure for these awards needs to be established,

Therefore be it resolved that the Treasurer will annually, in February, with the concurrence of the President, create two committees of three distinguished members each to select the recipient of both Awards. The consent of the Executive Council shall be sought via email on the composition of the committees, and

be it further resolved that the committees shall solicit brief nominations from the membership and acquire further documentation as needed to consider a slate of finalists for the awards, and

be it further resolved that if in a committee’s judgment no worthy candidates are nominated, the prize need not be awarded, and

be it further resolved that the Treasurer will disburse the prize money for these awards from the general funds of the Society.

HBES Resolution 2011- 1 Annual Conference Policies

Whereas the Society has a direct interest in the finances surrounding the Annual Conference, and

Whereas lead organizers ought to have the benefit of the experience of the members of the Executive Council, and

Whereas the lead organizer should stand to benefit from running a surplus from the conference,

Therefore be it resolved that the lead organizer of the Annual Conference will submit to the President of the Society a budget of expected expenses and revenues before the Conference is held on three occasions: nine months, six months, and three months before the conference is held. The Society’s coverage of any deficit of the Annual Conference shall be conditional on the timely submission of these there budgets. All budgets must be approved by a vote of the Executive Council.

Be it further resolved that the President will seek the advice surrounding the finances of the Annual Conference from the Executive Council and the Treasurer, and pass any appropriate guidance and suggestions to the lead organizer of the Conference.

  • Passed (8-0) 8/10/2011

HBES Resolution 2015-1A Council Member Travel Support

Whereas Executive Council members are required to attend all annual conference to conduct the business of the Society, and

Whereas the timing of the Executive Council meeting requires that members arrive one day in advance of the conference, and

Whereas attendance at annual conferences might place a financial burden on members, and

Whereas we would like to increase the pool of potential Executive Council members,

Therefore be it resolved that the Society will subsidize travel of members of the Executive Council. Specifically, the Treasurer will provide (1) the lesser of $750 and the total cost of travel, accommodations and registration to Executive Council members and (2) the lesser of $1,250 and the total cost of travel, accommodations and registration for the Student Representative. Members of the Council as constituted at the 2015 annual meeting are ineligible for this subsidy.

HBES Resolution 2020-1 Removal of Executive Council Member

Whereas Executive Council members represent the Society;

Whereas the Executive Council does not have a mechanism for removing a duly elected Executive Council member;

Therefore be it resolved that the Executive Council can, in extraordinary circumstances, and in the best interest of the society, remove a council member; a 2/3 vote (not counting the council member in question) is necessary for removal
