ELE is the geologic term for a mass extiction of 50% or more of species on the planet. Prof. Richard Leakey put the start of the 6th Great Extinction at 11,000 years ago with the development of the "Folsom Point" spear head, and the extinction of megafauna.
Ok Johhny thanks. "Extinction Level Event" = ELE then right?
I dunno about Leakey's assumption of the 6th one though,does he mean in North America?
Where the megafauna extinction is now also thought to be caused by other factors then just the arrival of human hunter gatherers by the way.
The Folsom point has precedence by many other lithic examples.
But wooden points are used even as we speak, or others.
Ask Sydney Possuelo who got one straight through the face....massive hardwood point nearly killed him as he researched hunter gatherers who prefer isolation.
There is a lot to be said how archeologists tend to overfocus on finds of stone points or tools.
It is simply not possible to preserve wood over time and us to find it except on rare occasions.
The Schoenignen spears were dated to several hundreds of thousands years old.
It seems very unlikely to me hunter gatherers would have wiped out the megafauna of America, even with stone points.
Imagine them in their many thousands....chucking atlatls or arrows at millions of large animals...no way.
Climate studies are showing us the huge impacts which make such events next to insignificant now.
Caused by impacts from space, Earth or industrial society as the man said.
The actual data now shows around 50-60% of life on land gone, more in the ocean.
Did that happen 11,000 years ago?
