Answer 1

Answer:

3.Chalcolithic period: Chalcolithic age can be considered as a transition period between Neolithic age and Bronze Age. This is the first metal age where metals like copper and its alloy bronze were discovered. As the name itself indicates, in this period both metal and stone were used for making tools vessels, for day to day life

4.Agriculture was introduced in the Aegean (modern day Turkey) around 8,500 years ago and steadily spread across Europe, reaching France around 7,800 years ago, and Britain, Ireland and northern Europe approximately 6,000 years ago. In all instances, the introduction of agriculture meant a drastic change in food production and consumption patterns, which led to a population boom. Utilizing radiocarbon dating, and an innovative new method for improving the accuracy of this data, the study's authors examined how population levels changed over time across Europe during the late Mesolithic, ("Middle Stone age") and Early Neolithic ("New Stone age").
