14 lut 2018 · I have surveyed technology, fire control and prospects for social proto-music in the Middle Pleistocene, the archaeological evidence for music in the Late Pleistocene, the musics of some ethnographically known forager groups, and considered theoretical implications from signalling theory.

The Mid-Pleistocene Transition (MPT), also known as the Mid-Pleistocene Revolution (MPR), [1] is a fundamental change in the behaviour of glacial cycles during the Quaternary glaciations. [2] The transition occurred gradually, [3] taking place approximately 1.25–0.7 million years ago, in the Pleistocene epoch. [4]
The mid-late Middle Pleistocene saw the emergence of the woolly mammoth (Mammuthus primigenius), and its replacement of Mammuthus trogontherii, with the replacement of M. trogontherii in Europe by woolly mammoths being complete by around 200,000 years ago.
It is currently defined as the time between c. 129,000 and c. 11,700 years ago. The late Pleistocene equates to the proposed Tarantian Age of the geologic time scale, preceded by the officially ratified Chibanian (commonly known as the Middle Pleistocene). [1]
3 kwi 2019 · Of particular interest is the transition between ~1.25 and ~0.7 Ma ago, known as the mid-Pleistocene transition (MPT) (5–7), from mostly symmetric cycles with a period of about 41 thousand years (ka) to strongly asymmetric 100-ka cycles. Several hypotheses for the mechanism of the MPT have been proposed.
2 gru 2015 · This interval, known as the Early–Middle Pleistocene transition (EMPT), essentially begins at 1.4 Ma with a relative decrease in the duration of interglacials and a change in the climate's sensitivity to orbital forcing (Lisiecki and Raymo, 2007).
23 mar 2023 · The Mid-Pleistocene Transition (~1.2–0.8 million years) corresponds to a time interval when high-amplitude ~100,000 years glacial–interglacial cycles replaced the more subdued ~40,000 years...
