A 62-year-old Havana Zoo biologist, Marta Llanes Torres, has spent one year raising two baby chimpanzees in her fifth floor Havana apartment - as if they were her own children. It's a full-time job, and Llanes is an expert. Anumá and Ada are the 35th and 36th chimps she has cared for. Llanes allowed me to chart the chimps' progress over the course of 12 months during regular visits to her house.
