The word Holocene was formed from two Ancient Greek words. Hólos is the Greek word for "whole". "Cene" comes from the Greek word kainós (καινός), meaning "new". The concept is that this epoch is "entirely new". [7] [8] [9] The suffix '-cene' is used for all the seven epochs of the Cenozoic Era.
The Holocene extinction, also referred to as the Anthropocene extinction, [3] [4] is an ongoing extinction event caused by human activities during the Holocene epoch. This extinction event spans numerous families of plants [ 5 ] [ 6 ] [ 7 ] and animals, including mammals , birds, reptiles, amphibians , fish, and invertebrates , impacting both ...
An epoch is the second smallest geochronologic unit. It is equivalent to a chronostratigraphic series. [14] [13] There are 37 defined epochs and one informal one. The current epoch is the Holocene. There are also 11 subepochs which are all within the Neogene and Quaternary. [2]
The scientific working group is proposing that Anthropocene Epoch followed the Holocene Epoch, which started about 11,700 years ago at the end of an ice age.
The 10th millennium BC spanned the years 10,000 BC to 9001 BC (c. 12 ka to c. 11 ka). It marks the beginning of the transition from the Palaeolithic to the Neolithic via the interim Mesolithic (Northern Europe and Western Europe) and Epipaleolithic (Levant and Near East) periods, which together form the first part of the Holocene epoch that is generally believed to have begun c. 9700 BC (c. 11 ...
The Holocene extinction event is currently under way. [12] Factors in mass extinctions include continental drift, changes in atmospheric and marine chemistry, volcanism and other aspects of mountain formation, changes in glaciation, changes in sea level, and impact events. [10]
Humans are in the midst of a current mass extinction, known as the Holocene extinction period, as it continues to the 21st century. And as it turns out — we are the culprits, as well.
Scientists believe that the sediment layers of a lake in Canada point to a new era marked by the damaging consequences of human activities.
