This taxon was traditionally thought to be a primitive stem lineage, from which all the larger bodied platyrrhines evolved (see Hershkovitz, 1977). However, Dr Susan Ford has argued quite convincingly that callitrichids are actually a dwarfed lineage.

 groups of about 5 or 6 animals. Their social organization is unique among primates and is called "Cooperative polyandrous group". This communal breeding system involves groups of multiple males and females, but only one female is reproductively active. Females mate with more than one male and everyone shares the responsibility of carrying the offspring.


They are the only primate group that regularly produce twins, which constitute over 80% of births in species that have been studied. Unlike other male primates, male callitrichids generally provide as much parental care as females, more in some cases. Typical social structure seems to constitute a breeding group, with several of their previous offspring living in the group and providing significant help in rearing the young.
