TL;DR: This review highlights the opportunities that development of arid conditions provides for rapid and diverse evolutionary radiations, and re-enforces the emerging view that Pleistocene environmental change can have diverse impacts on genetic structure and diversity in different biomes.

TL;DR: In the intertropical cold dry phase from ∼20,000 to 12,500 yr BP, the aggrading Nile was a braided, highly seasonal river as mentioned in this paper, and with a headwaters change to warmer, wetter conditions, it became an incised, sinuous, suspended load river.

TL;DR: This article reviewed terrestrial and near-shore marine records from equatorial and southern Africa between 30,000 and 10,000 years ago (30−10,000) to show how regional climates of the sub-continent have responded to orbital forcing as opposed to other global glacial-interglacial boundary conditions, and how they are related to high latitude climates, sea and land surface conditions, positions of the Intertropical Convergence Zone (ITCZ) and of the westerly belt.

TL;DR: In this paper, the authors have analyzed pollen from a marine core in the Bay of Bengal with stratified Toba ash, and the carbon isotopic composition of soil carbonates directly above and below the ash in three sites on a 400 km transect across central India.
