The current theory isn't that it's the earth's orbit that changes, but rather that there are regular changes to the angle of inclination on earth's axis. It's currently 23 degrees, but a lesser angle would mean cooler summers across the globe. In the northern and southernmost latitudes, this would mean that the previous winter's ice wouldn't completely melt prior to the next cooling season. Over time, this would result in significant glaciation, until the inclination of earth's axis moved back to 23 degrees.
The above argument that changes in the earth's orbit ended the last ice age isn't plausible. The earth moves in a slightly elliptical orbit, and is about a million miles closer to the sun in January than it is in July.
The Fire age.
The last glacial period is sometimes colloquially referred to as the 'last ice age'. But the use of 'ice age' is incorrect. Glacials, on the other hand, refer to colder phases within an ice age that separate interglacials. The end of the last glacial period is not the end of the last ice age. The end of the last glacial period was about 10,500 BCE, while the end of the last ice age has not yet come.
The present ice age has not ended, it started about 2.58 million years ago and we are living in an interglacial, (warm), period.
The ice age hasn't ended yet. It only started about 2.6 million years ago.
The last glacial period is sometimes colloquially referred to as the "last ice age", though this use is incorrect.Glacials, on the other hand, refer to colder phases within an ice age that separate interglacials. So the end of the last glacial period is not the end of the last ice age. The end of the last glacial period was about 10,500 BCE, while the end of the last ice age has not yet come.At the height of glaciation the Bering land bridge potentially permitted migration of mammals, including people, to North America from Siberia.
Either too much hunting caused the population to end, or the Ice Age was too cold for them.
Global climate change at the end of the last Ice Age.
Most likely, the end of the last ice age.
Most likely, the end of the last ice age.

The Pleistocene theory argues that hunter-gatherers caused the extinction of many species after the end of the last ice age.

A. Animal herds moved north, and hunter-gatherers followed.
The last ice age ended 100 000 years ago.
