We share 99+% of our genes with the Great Apes of Africa.

They also display ALL of the "supposedly" humans-only traits. From Parental love, through possessiveness, jealousy, hate, spite covetousness, greed, remorse, loneliness, stupidity and love etc.

The only REAL difference is that WE worry about why we are here, how we came to be and what will happen to us when we die.

Maybe we are over compensating for our inadequacies.
