Pleistocene

We know that some of man's close ancestors predated the Pleistocene.

At the end of the Pleistocene (around 10,000 B.C.), the technologies of food production may have already been employed on the fringes of the rain forests of western and central Africa, where the common use of such root plants as the African yam led people to recognize the advantages of growing their own food.

Middle and Late Pleistocene raised beaches in the Mediterranean are one instance of such movements.

In the Americas, most megafauna began disappearing by the end of the Pleistocene.

It soon became clear that there were multiple glacial ages during the Pleistocene, with warmer interglacial intervals between them.

The drift of the last glaciation was deposited during one of the most recent epochs of geologic time, the Pleistocene, which lasted from 1.8 million to 10,000 years ago.

Granted, the climate today is not as cold as it was in the Pleistocene.

The fossils buried in Pleistocene and earlier ocean sediments were of foraminifera—small, single-celled marine organisms that secrete shells of calcium carbonate, or calcite.

During the Pleistocene Ice Age , the ancient drainage systems were almost completely rearranged by glaciation.

In contrast with the Pleistocene cultures of the Levant, Natufian culture appears to have experienced considerable social change. 

Pleistocene rewilding is based on good intentions, but you know, it probably would just be more of the same thing.

Eh, actually, the proposal focuses on a particular subset of megafauna, the kind that lived during the Pleistocene epoch.

Ok. The Pleistocene epoch, most commonly known as the Ice Age, stretched from 1.8 million to 11,500 years ago.

They call their plan Pleistocene rewilding.

Now, the advocates of Pleistocene rewilding cite two main goals.

So during the Pleistocene epoch… let’s take the now extinct American cheetah, for instance.

Like Pleistocene rewilding could spark the re-emergence of large seeded American plants, such as the maclura tree.

But as I alluded to earlier, Pleistocene rewilding is extremely controversial.

In the years since the Pleistocene epoch, native species have adapted to the changing environmental there, plants, smaller animals, they have been evolving without megafauna for millennia.

By the early part of the twentieth century, scientists believed that four distinct glaciations had affected North America and Europe during the Pleistocene epoch.

Different ratios in the shells preserved in various layers of sediment reveal the temperature changes in the oceans during the Pleistocene epoch.

For example, from about 1.8 million years ago to around 11,000 years ago was the Pleistocene epoch.

The Pleistocene epoch was an ice age.

The Holocene epoch followed the Pleistocene epoch when the Earth’s climate warmed up around 11,000 years ago.

Quartz is quartz—a silicon ion surrounded by four oxygen ions—there’s no difference at all between two-million-year-old Pleistocene quartz and Cambrian quartz created over 500 million years ago.
