Explanation:
The Paleolithic Era is also referred to as the Old Stone Age the stage in human prehistory when we first developed stone tools and the longest stage of our prehistory from around 3 million years ago until 12,000 years ago. The Neolithic is the era when humans began to practice horticulture and started domesticating some animals and plants. This covers the period from about 12,000 to around 2,000 years ago. Basically, the Paleolithic is when humans first started to use stone tools, while the Neolithic era is when humans started farming. Tools were more advanced in the Neolithic and our ancestors also lived in more permanent homes.
