(Keating, 1985; Gillen, 1981; Perrett et al., 1998; Rhodes et al., 2000) may follow from how the brain discriminates between the sexes (Enquist et al., 2002). This latter fact suggests a method to distinguish generic biases from preferences shaped by a specific selection pressure. tested this idea by presenting mynhas (Gracula religiosa) with pictures of peacocks (Pavo cristatus), and showing that they preferred to approach and peck at we report on a similar experiment comparing human sexual preferences for faces with preferences developed by chickens in the course of a face discrimination task. no pecks occurred within 10 s, a new randomly chosen face was shown (after a Nevertheless, it is certainly desirable to extend our results by training animals to discriminate between the sexes based on individual faces.	./cache/work_ckvvh6adireabjr2kse77gmxwy.pdf	./txt/work_ckvvh6adireabjr2kse77gmxwy.txt
