A paternity test on a baby orangutan has come back with a surprising result.

Basel Zoo in northwestern Switzerland said Thursday the test showed 5-month-old Padma wasnB次元官网网址檛 fathered by the male in her enclosure.

Keepers routinely take DNA samples from newborn orangutans because the endangered great apes are part of a breeding program.

Researchers at Basel UniversityB次元官网网址檚 forensic laboratory compared PadmaB次元官网网址檚 DNA to that of Budi, a 14-year-old male living in the same enclosure as the babyB次元官网网址檚 mother, Maja.

They found it didnB次元官网网址檛 match BudiB次元官网网址檚 DNA. Instead, it matched 18-year-old orangutan Vendel, who lives in the next enclosure.

It appears that for Maja and Vendel, the dominant male at Basel Zoo, the dividing fence was no obstacle to some monkey business.
