A TIMELINE FOR THE PLANET

A very brief history of the planet, with dates.How all the main specialties Ė life, geology and climate Ė tie up.††

 

Thatís what Iím aiming for anyway (more), though Iíve a lot of work still to do.And itís not actually a time line, on account of Wordís limitations as a website design tool.

 

Iím aiming at ordinary folk like me.But I hope Iím sufficiently authoritative to be useful to scientists too.Where Iím not authoritative, I hope Iíve made it clear.Iím also controversial when I feel the need Ė but I hope Iíve made that clear too.If you find anything wrong, in your area of expertise, please click here

How this site works

The table below covers the entire History of the Universe Ėall 13 thousand million years Ė kMy Ė of it.

But a click takes you to a more detailed table covering Ďonlyí the 4Ĺ kMy of the life of the planet.

Another click takes you to the ĎAge of large animals and plantsí Ė a mere 500 My.

And so on, ending up with the ĎAge of Humansí.†† For post ice-age events Iíve resorted to a series of essays covering my take on the major developments.
