Question

What did humans and all other animals in the new stone age depend on for satisfying their needs?​

Answer 1

Answer:

The New Stone Age (Neolithic Era)

Like the Old Stone Age, the people of the New Stone Age used stone for tools. Neo is a root we use in the English language, it comes from the Greek word neos, which means new or recent. So, Neolithic means "New Stone."

If people were still using mostly stone for tools, why do we bother separating these two eras? The New Stone Age was a time when the Earth's climate was warmer than the climate in the Old Stone Age. No one knows for sure why the Earth warmed; around 12,000 years ago the Earth ended its last great ice age.
