 Geologic Time: The Pleistocene
However, one group of early human lineages, the robust australopiths, suffered extinction in the early part of the Pleistocene.
Environmental fluctuation during the Pleistocene was apparently conducive to human evolution, which is characterized by an increase in the adaptability of the human lineage.
The Pleistocene is the fifth epoch of the Cenozoic; it started approximately 1.8 million years ago and ended 11,000 years ago.

 Field Trip To Pleistocene Lake Manix, Mojave Desert, California
The fossil mammal bones from the Pleistocene exposures were discovered sometime in the early 1900s by John T. Reed of San Bernardino, California.
The older of the two lakes disappeared, they concluded, due to desiccation, while the younger body of water vanished--as Buwalda had claimed many years before, when the overflow channel at Afton Canyon was eventually downcut enough to allow the ancestral Mojave River to flow freely across the land, draining the lake.
Specimens of the Tui Chub and Three-spine stickleback, while found scattered throughout the fine silts and sands of the upper half of the Manix Formation, are often concentrated in the middle of the sedimentary section in strata roughly 290 thousand years old.

It followed Pleistocene epipalaeolithic and early Holocene Mesolithic cultures with the start of farming and ended when metal tools came into widespread use in the Copper Age ( chalcolithic), Bronze Age or Iron Age, depending on geographical region.
The term "Neolithic" is associated with a suite of specific behavioural characteristics including the growing of crops and the use of domesticated animals.

 Early Man Site
The history of the Early Man Site dates back to the early ’40s after an amateur archeologist stumbled upon what appeared to be stone tools while exploring an area that was once the shoreline of a Pleistocene lake.

 ABC Science - Australian Beasts- Why the beasts died
Perhaps the early people of Australia hunted the megafauna to extinction or new land management practices — in particular the introduction of firestick farming — may have altered the environment too much for the megafauna to survive.

He reasons that as early hunter-gatherers followed their prey, they triggered local extinctions which ultimately drove total populations down the slippery slope to extinction.
Fullagar says the site provides evidence that humans and megafauna coexisted for some 10,000 years, casting doubt on the proposition that people quickly did in the big critters.

 The California Condor on the Colorado Plateau
There is evidence indicating that condors returned to the southwest as early as the 1700s in response to the introduction of large herds of cattle, horses, and sheep that replaced the extinct Pleistocene megafauna as a source of carrion.
The disappearance of the condor and other large scavenging birds from these regions coincided with the extinction of the Pleistocene mammalian megafauna, their primary food source.
California condors nested in west Texas, Arizona, and New Mexico during the Late Pleistocene.

The results indicate that man did not produce these lithics but, rather, that they were created naturally.

He tells me that, if there was one thing which used to completely floor him early on in this research, it was the extent to which most of these tribes retain oral traditions of Indians having to deal not only with pleistocene megafauna, but with dinosaurs as well.
Thus, in the story of large animals at Pomme de Terre prairie in southwestern Missouri, a variant of the story suggests that the western animals were megafauna and the creatures who crossed the Mississippi and Missouri Rivers and invaded the lands of the megafauna were dinosaurs.

 New Evidence on the Antiquity of Piltdown Man
Any such post-Villafranchian elements might theoretically be of first interglacial age (when according to Hopwood's terminology the "Middle Pleistocene" fauna began to appear); of great interglacial age (that is, Middle Pleistocene of all authors), or of last interglacial age (that is, early Upper Pleistocene of some authors, late Middle Pleistocene of others).
The question of the precise geological age of the Piltdown gravel is open to further inquiry, but taking the balance of available evidence, Eoanthropus may be provisionally referred to the last warm interglacial period (Riss-Würm interglacial; that is, early Upper Pleistocene, although here it should be noted that some authorities count Russ-Würm as Middle Pleistocene).
Since distinctively Cromerian forms are absent and as there are indications that the deposit has been repeatedly re-worked, the post-Villafranchian material is probably partly Middle and partly Upper Pleistocene.

 FSU Anthropology - Körös Regional Archaeological Project
Initially deposited by a series of rivers (Tisza, Szamos, Kraszna, and Bodrog) during the Pleistocene, the Nyírség was uplifted during the early Holocene, creating a substantial boundary to later streambeds.
During the early Holocene, tectonic processes shifted the bed of the Tisza further to the north, where it currently enters the Plain north of the Nyírség at the Tokaj Gate, leaving behind a large deltaic plain (the Dévaványa plain; see Sherratt 1997b:296-7) that was cross-cut by a series of much smaller lowland rivers.
Created by the continuous meandering of the Tisza, Berettyó, and Körös rivers throughout the Holocene, this region was annually inundated by early spring and early summer floods.

 Roy Sugarman reviews Under the Canopy: The Archaeology of the Tropical Rain Forests. Edited by Julio Mercader
The fact that it was only recently that archaeologists began to document the Pleistocene occupation of tropical forested regions says more about the nature of archaeological research than it does about early human adaptations to such ‘harsh’ environs (page 239).
The Sahara for instance was not the wasteland we now see, not in the Pleistocene anyway, nor did the capabilities of the early hominids restrict their movement here, with a strong archaeological record of bifaces and picks in areas such as Ghana, with later small flaked-stone industries found all over West Africa.
The macrolithic material in itself is thought to be a derivative of that found in early adaptations to a heavily forested environment.

The Early Quaternary is known as the Pleistocene Epoch and stretches from 3 mya until 10,000 years ago.
Core samples of deep ocean sediments provide evidence that there were more than 16 glaciations during the Quaternary Period, starting at the beginning of the Pleistocene Epoch.
The minor features, such as the final rounding of surface features, the alignment of surface lineations, surficial deposits and sea level changes, are the product of glacial activity during the Quaternary Period.
