Shocked, shocked to find some macaques hurt young!
From ANIMAL PEOPLE, July/August 1998:
ATLANTA––Thirty-five years of records
pertaining to the sooty mangeby and pigtail macaque
colonies at the Yerkes Regional Primate Research
Center show that about 5% of their newborns are abandoned
by their mothers, who tend to be the least experienced
mothers, while another 5% to 10% are actively
abused by mothers who range in age and tend to repeat
the abuse with successive offspring.
This parallels the rates of infant neglect and
child abuse in humans, and is reason, argued
researchers Dario Maestripieri and Kelly A. Carroll in
the May 1998 edition of Psychological Bulletin, that
the use of nonhuman primates in researching neglect
and abuse should be stepped up.
