Natasha, a black Macaque in the Safari Park Zoo near Tel Aviv, Israel surprised scientist by the difference between her from others Macaque. Black Macaque, like others monkey usually walks on all four and occasionally they will walk upright for a short period of time. Natasha walks upright all the time, bearing similarity to the walking style of the legendary creature Bigfoot with not such a big foot.

In 2004, Natasha went through a death experience, a stomach ailment that almost killed her. She and three other monkeys were diagnosed with severe stomach flu. At the zoo clinic, she slipped into critical condition. The veterinarian Igal Horowitz that's treating Natasha said "I was sure that she was going to die," he said. "She could hardly breathe, and her heart was not functioning properly."

After intensive treatment, Natasha's condition began to stabilize. But a day after she was released from the clinic, she soon starts to walk upright from this day onwards. Horowitz was baffled, and said that the possible explanations to her advanced evolution of movement might due to her brain being damaged from the illness. Probably she thought that she has become Bigfoot. But apart from her evolutional walking style, her others monkey behavior remain unchanged.
