My Thursday LA Times says the that Feb 27 Nature reports someone found
"perfectly preserved 400,000 year old wooden spears"!  If true, this
suggests there is a bigger gap than we thought beteen creatures able
to make advanced tools and us, highlighting the mystery:  Just what
*did* happen to humans in the last 50,000 years?
