What do archaeologists now believe is the most fundamental difference between the neolithic and paleolithic eras?

The Paleolithic Era (or Old Stone Age) is a period of prehistory from about 2.6 million years ago to around 10000 years ago. In the Paleolithic era, there were more than one human species but only one survived until the Neolithic era. Paleolithic humans lived a nomadic lifestyle in small groups. In the Paleolithic era, there were more than one human species but only one survived until the Neolithic era. Paleolithic humans lived a nomadic lifestyle in small groups. They used primitive stone tools and their survival depended heavily on their environment and climate. Neolithic humans discovered agriculture and animal husbandry, which allowed them to settle down in one area. The Mesolithic era followed the Paleolithic era but the period of the Paleolithic/Mesolithic boundary varies by geography by as much as several thousand years.
