Explanation:
Stone Age Tools
Much of what we know about life in the Stone Age and Stone Age people comes from the tools they left behind.
Hammerstones are some of the earliest and simplest stone tools. Prehistoric humans used hammerstones to chip other stones into sharp-edged flakes. They also used hammerstones to break apart nuts, seeds and bones and to grind clay into pigment.
Archaeologists refer to these earliest stone tools as the Oldowan toolkit. Oldowan stone tools dating back nearly 2.6 million years were first discovered in Tanzania in the 1930s by archaeologist Louis Leakey.
Most of the makers of Oldowan tools were right-handed, leading experts to believe that handedness evolved very early in human history.
As technology progressed, humans created increasingly more sophisticated stone tools. These included hand axes, spear points for hunting large game, scrapers which could be used to prepare animal hides and awls for shredding plant fibers and making clothing.
Not all Stone Age tools were made of stone. Groups of humans experimented with other raw materials including bone, ivory and antler, especially later on in the Stone Age.
Later Stone Age tools are more diverse. These diverse “toolkits” suggest a faster pace of innovation—and the emergence of distinct cultural identities. Different groups sought different ways of making tools.
Some examples of late Stone Age tools include harpoon points, bone and ivory needles, bone flutes for playing music and chisel-like stone flakes used for carving wood, antler or bone.
Answer:
The diversity and richness of Philippine literature evolved side by side with the country's history. This can best be appreciated in the context of the country's pre-colonial cultural traditions and the socio-political histories of its colonial and contemporary traditions.The average Filipino's unfamiliarity with his indigenous literature was largely due to what has been impressed upon him: that his country was "discovered" and, hence, Philippine "history" started only in 1521. So successful were the efforts of colonialists to blot out the memory of the country's largely oral past that present-day Filipino writers, artists and journalists are trying to correct this inequity by recognizing the country's wealth of ethnic traditions and disseminating them in schools and in the mass media. The rousings of nationalistic pride in the 1960s and 1970s also helped bring about this change of attitude among a new breed of Filipinos concerned about the "Filipino identity."
