The Bronze Age arrived circa 1500 BC when people in the region were turning copper into bronze, growing rice and domesticating poultry and pigs; they were among the first people in the world to do so. Human remains and artifacts from this era were discovered in Monywa District in the Sagaing Division. The Iron Age began around 500 BC with the emergence of iron-working settlements in an area south of present-day Mandalay. Evidence also shows the presence of rice-growing settlements of large villages and small towns that traded with their surroundings as far as China between 500 BC and 200 AD. Iron Age Burmese cultures also had influences from outside sources such as India and Thailand, as seen in their funerary practices concerning child burials. This indicates some form of communication between groups in Myanmar and other places, possibly through trade.
When did the Age of Iron begin?
A: The Iron Age began around 500 BC

CDs are susceptible to damage during handling and from environmental exposure. Pits are much closer to the label side of a disc, enabling defects and contaminants on the clear side to be out of focus during playback. Consequently, CDs are more likely to suffer damage on the label side of the disc. Scratches on the clear side can be repaired by refilling them with similar refractive plastic or by careful polishing. The edges of CDs are sometimes incompletely sealed, allowing gases and liquids to corrode the metal reflective layer and to interfere with the focus of the laser on the pits. The fungus Geotrichum candidum, found in Belize, has been found to consume the polycarbonate plastic and aluminium found in CDs.
Where is the metal reflective layer located?
A: unanswerable

Jeffrey Long and Rick Kittles give a long critique of the application of FST to human populations in their 2003 paper "Human Genetic Diversity and the Nonexistence of Biological Races". They find that the figure of 85% is misleading because it implies that all human populations contain on average 85% of all genetic diversity. They claim that this does not correctly reflect human population history, because it treats all human groups as independent. A more realistic portrayal of the way human groups are related is to understand that some human groups are parental to other groups and that these groups represent paraphyletic groups to their descent groups. For example, under the recent African origin theory the human population in Africa is paraphyletic to all other human groups because it represents the ancestral group from which all non-African populations derive, but more than that, non-African groups only derive from a small non-representative sample of this African population. This means that all non-African groups are more closely related to each other and to some African groups (probably east Africans) than they are to others, and further that the migration out of Africa represented a genetic bottleneck, with much of the diversity that existed in Africa not being carried out of Africa by the emigrating groups. This view produces a version of human population movements that do not result in all human populations being independent; but rather, produces a series of dilutions of diversity the further from Africa any population lives, each founding event representing a genetic subset of its parental population. Long and Kittles find that rather than 85% of human genetic diversity existing in all human populations, about 100% of human diversity exists in a single African population, whereas only about 70% of human genetic diversity exists in a population derived from New Guinea. Long and Kittles argued that this still produces a global human population that is genetically homogeneous compared to other mammalian populations.
How much human genetic diversity exists in a single African population?
A:
100%
