This article may be confusing or unclear to readers. Holocene marine deposits along low-latitude coastlines are rare because the rise in sea levels during the period exceeds any likely tectonic uplift of non-glacial origin. United Nations Environment Programme. From Wikipedia, the free encyclopedia. This article is about the geological epoch.

Human impacts on modern-era Earth and its ecosystems may be considered of global significance for future evolution of living species, including approximately synchronous lithospheric evidence, or more recently atmospheric evidence of human impacts. Climate cyclicity through the Holocene Bond events has been observed in or near marine settings and is strongly controlled by glacial input to the North Atlantic. Tell us a little about yourself to get started. They find a general correspondence across Eurasia and North America, though the method was once thought to be of no interest. With Speed and Violence.

Greater moisture in the polar regions has caused the disappearance of steppe-tundra. The temporal and spatial extent of Holocene climate change is an area of considerable uncertainty, with radiative forcing recently proposed to be the origin of cycles identified in the North Atlantic region.

Climate cyclicity through the Holocene Bond events has been observed in or near marine settings and is strongly controlled by glacial input to the North Atlantic. Animal and plant life have not evolved much during the relatively short Holocene, but there have been major shifts in the distributions of plants and animals.

A number of large animals including mammoths and mastodons , saber-toothed cats like Smilodon and Homotherium , and giant sloths disappeared in the late Pleistocene and early Holocene—especially in North America, where animals that survived elsewhere including horses and camels became extinct.

This extinction of American megafauna has been explained as caused by the arrival of the ancestors of Amerindians ; though most scientists assert that climatic change also contributed. In addition, a controversial bolide impact over North America has been hypothesized to have triggered the Younger Dryas.

Throughout the world, ecosystems in cooler climates that were previously regional have been isolated in higher altitude ecological "islands". It has been suggested that this event was caused by the final drainage of Lake Agassiz , which had been confined by the glaciers, disrupting the thermohaline circulation of the Atlantic. The beginning of the Holocene corresponds with the beginning of the Mesolithic age in most of Europe ; but in regions such as the Middle East and Anatolia with a very early neolithisation , Epipaleolithic is preferred in place of Mesolithic.

Cultures in this period include Hamburgian , Federmesser , and the Natufian culture , during which the oldest inhabited places still existing on Earth were first settled, such as Jericho in the Middle East. The Late Holocene brought advancements such as the bow and arrow and saw new methods of warfare in North America.

Spear throwers and their large points were replaced by the bow and arrow with its small narrow points beginning in Oregon and Washington. Villages built on defensive bluffs indicate increased warfare, leading to food gathering in communal groups for protection rather than individual hunting.
