LOS ANGELES (FOX 11) - Famed primatologist Jane Goodall was honored Wednesday by Los Angeles city leaders on her 85th birthday.
Goodall vocalized a chimpanzee greeting Wednesday at the Los Angeles City Hall ceremony and pulled Mayor Eric Garcetti over to demonstrate how a female chimpanzee greets a high-ranking male.
City leaders also sang “Happy Birthday” to her.
The chimpanzee expert shared about her experiences in Los Angeles over the years, most recently at the 2017 screening of the documentary "Jane" at the Hollywood Bowl that featured a live orchestral performance.
Goodall said her relationship with Los Angeles is "very deep and very real and very true."
Traveling from England to Tanzania at the age of 26, Goodall set her sights on studying the little-known world of wild chimpanzees and revolutionized the understanding of chimpanzee behavior through her long-term study.
One of her most important discoveries includes tool making in chimpanzees, previously considered the defining difference between humans and other animals.
She later founded the Jane Goodall Institute and has become known as an advocate for environmental issues, animal welfare and human rights.
In April 2002, she was named a United Nations Messenger of Peace.
