Mass extinction comes every 62 million years, UC physicists discover

There does not seem to be a Topic for "Science" and this could be considered History

Unlike global warming. climate change or glaciation, there does not seem to be a political component.

Mass extinction comes every 62 million years, UC physicists discover

(http://www.sfgate.com/cgi-bin/article.cgi?f=/c/a/2005/03/10/MNGFIBN6PO1.DTL)

With surprising and mysterious regularity, life on Earth has flourished and vanished in cycles of mass extinction every 62 million years, say two UC Berkeley scientists who discovered the pattern after a painstaking computer study of fossil records going back for more than 500 million years

Their findings are certain to generate a renewed burst of speculation among scientists who study the history and evolution of life. Each period of abundant life and each mass extinction has itself covered at least a few million years -- and the trend of biodiversity has been rising steadily ever since the last mass extinction, when dinosaurs and millions of other life forms went extinct about 65 million years ago.

The Data kind of indicates we should be experiencing a Mass Extinction

Right now actually

Maybe if we are good, us humans can help with mass extinction this time. The dinosaurs would be so jealous.

America it seems it's your time now...

[alpine-frolic]

The beginning of the credit mass extinction began in 2007!

Alpine-frolic: America it seems it's your time now...

If it is, then the whole world's time is now. Except for some 3rd world countries. They might not notice.

Consider me as living in a 3rd world country then.
If we must stop to sell Airbus we will learn how to fabric puzzles, how to play bridge and drink tea with roasties; life will look like heaven.

LOL it would appear there is no topic including something that has been happening in 62 million year cycles that cannot end up with a statement about America, we are almost like Global Warming in that regards no matter WHAT happens it will be claimed that CO2 and US SUVs are a facet.

If my history is good Mass extinction comes to the L.L. forum every 4 years:faint:

why does all the bad things have to happen in my lifetime???:confused:

You must have had one HECK of a LONG life!!!

Now now not ALL bad things happen in your life time, we have not got hit by an asteroid yet. Which took out 50% of all Life during the End-Cretaceous Extinction



and what ever happened that caused the Pre-Cambrian die off when all forms of life except a few unicellular oganisms died of has not happened
"The first extinction of the Precambrian, which largely affected stromatolites and acritarchs, has been correlated with a large glaciation event that occurred about 600 million years ago. This event was of such severity that almost all micro-organisms were completely wiped out."

I am certain we would have noticed


BTW except for the Dinosaur Killer indicated by the The K-T Boundary

Seems to be the only one not caused by glaciation, remind me again
why are we concerned because some glaciers are retreating???

we have not got hit by an asteroid yet.

that's because Bruce Willis blew it up before it hit :becky:
