Man's still an ape. They prosecuted some poor sucker in these United States For teaching that man descended from the apes. If they'd seen me chasing you, sugar, through the jungle last night. They are the only known species of primate besides man that performs sex in that position. It was also announced on the program, but now shown, that bonobos engage in oral sex and homosexual-like behaviors.
Some scientists believe that bonobos are the species of chimpanzee most like man.
This paper has a picture of all the chromosomes of man, chimpanzees, gorillas, and orangutans with each pair of chromosomes lined up next to each other and showing the 1000 band stage with all the sections labeled. Just by examining the picture you can clearly see that the chromosomes are remarkably similar. The differences are equally revealing as a vast majority are simple inversions of sections of chromosomes. The evolutionary explanation is that the numbers, lengths and banding patterns of the chromosomes of these species were simply inherited from common ancestors. Utilizing modern tricks of the trade geneticists in England have cross-bred a goat and a sheep.
