Info Post

Click here for a very cool Interactive Time Line from the Smithsonian.

From the Time Line:  The Holocene is a chronostratigraphic division that follows the Pleistocene Epoch. By consensus, it covers the last 11,500 years of Earth history. It is an important time to scientists because during this epoch most of our modern landscapes and soils evolved. In addition, significant changes in global climate occurred as the Earth moved into a postglacial — or interglacial — regime. In areas that were glaciated, this transition is marked by a clear stratigraphic boundary due primarily to the scouring effects and debris that retreating glaciers left on the landscape.

Defining Characteristics: impact of Homo sapiens and technology; Secondary Characteristics: climate warming following the last ice age; continents drying out, polar areas contract; plant communities shifting with the climate.
