““The discovery is contrary to the belief of many scientists that apes lack the brain structure for the use of symbolic language in complex communications, said E. Sue Savage-Rumbaugh of Georgia State University. . “Bonobos, apes that closely resemble chimpanzees, live in very dense forest with only faint trails. They live in bands of more than 100 and each night rest together in trees. “During the day, the apes separate into small groups and forage for food, often travelling for miles and m...oving silently to avoid predators. “And yet, when the day ends, members of the band find their way back together at a new resting place. “Savage-Rumbaugh said this behavior shows that the animals communicate. She noticed that whenever a trail crossed another trail, the lead group would stamp down vegetation or rip off large leaves and place them carefully. “’What they are doing is leaving little notes in the vegetation,’ she said.MoreLessRead More Read Less
