The Pleistocene epoch is a period of time that occurred 1.8 million to 11,000 years ago. It is during this period that modern man evolved althogh our relatives in the genus Homo have been present since the late Pliocene. The Pleistocene is also known for its frequent glaciations. Many large animals went extinct at the end of this period including sabre toothed tigers, wooly mammoths, and neanderthals, our sister species. This epoch coincided with ice ages which ravaged the earth as well as interglacials. It is thought that the Pleistocene ice age is still ongoing and that we are merely in another interglacial althogh global warming may result in a superinterglacial. This will delay or prevent us from going into another ice age.

Pleistocene extinctions

Flora and Fauna in the Pleistocene were very similar to what is found today. Many of the same species of mollusks, birds, mammals, and insects still exist. The Pleistocene however, was also characterized by many large mammals which are now extinct. These include giant sloths, neanderthals, wooly mammoths, and sabre toothed cats. Horses and camels once galloped across the North American plains and giant birds with 25 foot wingspans stalked prey. Scientists speculate that the Pleistocene mass extinction event may have been caused by a combination of changing climate, disease, and overhunting by humans.

Young earth creation scientists view

Young earth creationist scientists believe that the evolutionary geological timescale is in error. [1][2][3] These scientists believe that the earth is young and has multiple lines of evidence from the field of geology showing that the earth is young. [4][5][6][7][8] Also, young earth creationist scientists assert that there is an abundance of scientific arguments in addition to geology showing the earth and universe are both approximately 6,000 years in age.[9][10][11] In addition, young earth creationist scientists have a number of arguments against the position of an extremely old age for the earth and the universe.[12][13][14][15] Flood geologists also point out that catastrophism is increasingly being accepted in the field of geology. [16] [17] In addition, creationists also assert that old earth uniformitarian geology has numerous anomalies. For example, creationists cite the work of William R. Corliss who catalogued numerous anomalies in the old earth uniformatarian geology paradigm. [18][19] Corliss wrote regarding paraconformities the following:


“

"Potentially more important to geological thinking are those unconformities that signal large chunks of geological history are missing, even though the strata on either side of the unconformity are perfectly parallel and show no evidence of erosion. Did millions of years fly by with no discernible effect? A possible though controversial inference is that our geological clocks and stratigraphic concepts need working on." William R. Corliss, Unknown Earth (Glen Arm, Maryland: The Sourcebook Project, 1980), p. 219. [20]

”

The secular science journal New Scientist wrote regarding Corliss's work the following: "All I can say to Corliss is carry on cataloging." [21] Young earth creationist scientists assert that paraconformaties pose a serious challenge to the old earth uniformitarian geology paradigm. [22][23][24]
