"After she passed, the chimps examined the body, inspecting Pansy’s mouth, pulling her arm and leaning their faces close to hers. Blossom sat by Pansy’s body through the night. And when she finally moved away to sleep in a different part of the enclosure, she did so fitfully, waking and repositioning herself dozens more times than was normal. For five days after Pansy’s death, none of the other chimps would sleep on the platform where she died."—

Indeed, at 6 million years of separation, the difference in [Y-chromosome] gene content in chimpanzee and human is more comparable to the difference in autosomal gene content in chicken and human, at 310 million years of separation.
It is commonly said that the Human and Chimpanzee genomes share 99% or more identical DNA. In a surprising development about to be published in Nature
, the Y-chromosomes of these two species were found to share only 70% of their DNA, raising important questions about the mode and tempo by which speciation from a common ancestor occurred. This finding may point the finger
at the evolution of different patterns of sperm-competition and mating practices within these two species.

The Hunt for the Origin of AIDS
"The notion that AIDS arose from a polio vaccine made with contaminated chimpanzee cells is far from the only theory about how the epidemic started, and it is hotly disputed. The quest for the source of the epidemic is intensifying, as researchers scour the jungle for clues and try to "walk back" the disease genetically with the help of the world's most powerful computers."

Nigerian Boy Raised by Chimps.
I swear I'm not making this up. A disabled two-year-old Fulani boy was abandoned by his nomadic family because he was mentally and physically disabled, and was raised by a chimpanzee family in Nigeria's Falgore forest for a year and a half. He was found by hunters several years ago, and now lives in a children's home, where he walks and vocalizes like a chimpanzee, unable to communicate with humans normally. So the obvious question: Is it better to have taken this child away from his chimp family to live in an orphanage, or should they have let him continue to live in the forest?
