The prehistoric period during which the earliest forms of human language (articulate speech) are believed to have begun is the:
Answer:
Middle Paleolithic
While the exact origin is debated, anatomical and genetic evidence (like the development of the hyoid bone and the FoxP2 gene) suggests that the ability for more complex, **articulate speech** began to emerge with *Homo heidelbergensis* and **Neanderthals** during the **Middle Paleolithic**, reaching its full capacity with *Homo sapiens*.
20682
The development of permanent dwellings, often semi-subterranean, at the Mesolithic site of **Lepenski Vir** (Serbia) is an example of:
Answer:
Sedentism based on intensive fishing resources
**Lepenski Vir** is a key Mesolithic site that shows that sedentism and permanent structures were sometimes possible *before* agriculture, driven by the reliable and **intensive exploitation of aquatic resources** (fishing) from the Danube River.
20683
The earliest known domesticated crop in the Yellow River valley of China, marking the start of the Neolithic there, was:
Answer:
Millet
While rice was domesticated in the Yangtze River valley, the northern Chinese Neolithic, represented by cultures like the Yangshao, focused on the domestication of **Millet** (specifically foxtail and broomcorn millet) in the **Yellow River valley** as their primary staple crop.
20684
The use of **polished stone axes (celts)** was most crucial in the Neolithic period for facilitating:
Answer:
Forest clearance for agriculture
The advent of the strong, sharp **polished stone axe (celt)** in the Neolithic was vital for the **clearance of forests** to create arable land, a necessary prerequisite for the expansion of settled agriculture.
20685
Which Chalcolithic site in India is famous for its intricate burial practices, including the practice of **urn burial** for children?
Answer:
Inamgaon
**Inamgaon**, a major Jorwe Chalcolithic site in Maharashtra, is well-known for its detailed funerary evidence. A common practice was the **urn burial** of children, where the remains were placed in one or two large clay urns and buried within the house floor.
20686
The term **'Acheulian'** refers to the stone tool industry characterized by what specific type of tool?
Answer:
Large, symmetrical, oval or pear-shaped hand-axes
The **Acheulian industry** (Lower Paleolithic) is defined by the prevalence of its distinctive, skillfully manufactured **bifacial hand-axes**. These tools were multi-purpose, used for chopping wood, butchering animals, and digging.
20687
The primary cause of the significant environmental changes, including sea-level rise and the transformation of global flora and fauna, that marked the transition to the Mesolithic Age was:
Answer:
The end of the Pleistocene Ice Age
The shift from the Paleolithic to the **Mesolithic** (and the start of the Holocene epoch) was primarily driven by the melting of continental glaciers and the subsequent **end of the Pleistocene Ice Age**, leading to warmer temperatures, higher sea levels, and the expansion of forests.
20688
The **Neolithic Revolution** led to the development of **Sedentary Life**. This term means:
Answer:
A settled lifestyle in permanent villages
**Sedentary life** (or sedentism) is the practice of living in one place for a long time. It was made possible and necessary by the development of agriculture in the Neolithic Age, as farmers had to remain near their fields and domesticated animals.
20689
The **Lower Paleolithic** is primarily associated with which two traditions of stone tools in succession?
Answer:
Oldowan and Acheulian
The **Lower Paleolithic** spans the earliest tool use. It begins with the simple chopper tools of the **Oldowan** tradition (*Homo habilis*), followed by the more complex, bifacially worked hand-axes and cleavers of the **Acheulian** tradition (*Homo erectus*).
20690
The Chalcolithic cultures of Central India are particularly known for the cultivation of **lentils** and the practice of **rotation of crops**, which is a sign of:
Answer:
Highly developed, sustainable agriculture
The cultivation of various crops, including legumes like **lentils** and cereals, along with evidence for **crop rotation**, suggests that Chalcolithic farmers had a well-developed understanding of soil fertility and sustainable agricultural practices, indicating a high degree of skill.
