Study with aye-ayes, slow loris finds that prosimians prefer alcohol

In the first controlled study of its kind using nectar-simulating solutions, researchers found that two aye-ayes and another prosimian primate (slow loris) could discriminate different concentrations of alcohol and that each species preferred the highest concentrations of alcohol available to them. The study investigates the genetic mutation and potential adaptive advantage that some primates have in efficiently metabolizing alcohol and examines the importance of fermented foods in human evolution.
