Scientific controversy with radioisotopic dating

A major event is a general glacial excursion, termed a "glacial". During a glacial, the glacier experiences minor advances and retreats.

During the Paleolithic period, humans grouped together in small societies such as bands, and subsisted by gathering plants and fishing, hunting or scavenging wild animals.The first evidence of human fishing is also noted, from artifacts in places such as Blombos cave in South Africa.Archaeologists classify artifacts of the last 50,000 years into many different categories, such as projectile points, engraving tools, knife blades, and drilling and piercing tools.The small populations were then hunted out by Paleolithic humans.The global warming that occurred during the end of the Pleistocene and the beginning of the Holocene may have made it easier for humans to reach mammoth habitats that were previously frozen and inaccessible.
