Chimps in Gombe NP, Tanzania
There's only 1.4% difference in our DNA.
(Reassuringly we also apparently share 40% of our DNA with mushrooms).
One young male came and lay down about five feet away and stayed there for ten minutes.
In spite of thier small size in comparison to gorillas they are a lot more violent. They kill other animals - monkeys and also thier own kind like we do.
