Yep it's the same behavior with apes. The apes eat bananas. Then one ape of a group of apes decides to eat something unknown and drops dead. Other apes try the same and drop dead. Meanwhile the apes are throwing away the bananas cause it must have been the bananas who are responsible for the dead, cause the unknown IS UNKNOWN and therefore cannot be responsible for the dead apes. After everything is said an done, only one ape is left. What will this ape do ?
