ANTC23H3 Lecture Notes - Galago, Polygynandry, Mate Choice
Document Summary
Wide variety of penile morphology, even among closely related primate species. Can use penile morphology alone to tell galago species apart. Just by penis shape they can tell what species they are looking at. Penis are more differentiated than the body shape. 9. 2 uo (urethal opening where semen comes out) they all fit pretty well. If you look at other species such as galago you don"t see one-to-one correspondence: problems with this hypothesis: In some species with diverse penile morphology (i. e. galagos), male and female genitalia do not match . Matching between different primates species can occur. i. e. captive galagos. Other mechanisms keep different species from inter-breeding. Strong support for this hypothesis is lacking: genitalic recognition hypothesis. Variant of the lock and key hypothesis females" bodies recognize males of their species by the stimulation they receive during mating makes more sense for species that are induced ovulators.
