The higher-level phylogeny of the arthropods continues to be a matter of debate and research. In 2008, researchers at Tufts University uncovered what they believe is the world's oldest known full-body impression of a primitive flying insect, a 300 million-year-old specimen from the Carboniferous period. The oldest definitive insect fossil is the Devonian Rhyniognatha hirsti, from the 396-million-year-old Rhynie chert. It may have superficially resembled a modern-day silverfish insect. This species already possessed dicondylic mandibles (two articulations in the mandible), a feature associated with winged insects, suggesting that wings may already have evolved at this time. Thus, the first insects probably appeared earlier, in the Silurian period.
With what type of insect is a dicondylic mandible associated?
A: winged

There were several protests along the torch relay route. Members of the Hong Kong Alliance in Support of Patriotic Democratic Movements in China, including pro-democracy activist Szeto Wah, waved novelty inflatable plastic Olympic flames, which they said symbolised democracy. They wanted accountability for the Tiananmen Square protests of 1989 and the implementation of democracy in Hong Kong. Political activist and Legislative Council member Leung Kwok-hung (Longhair) also joined the protest, saying "I'm very proud that in Hong Kong we still have people brave enough to speak out." Pro-democracy activists were overwhelmed by a crowd of torch supporters with insults like "running dog," "traitor," "get out!," and "I love the Communist Party." At the same time, about 10 members of the Civil Human Rights Front had orange banners calling for human rights improvements and universal suffrage. Onlookers were saying "Aren't you Chinese?" in Mandarin putonghua as they tried to cover the orange banners with a large Chinese national flag. One woman had an orange sign that said, "Olympic flame for democracy", while a man carried a poster with a tank and the slogan "One world, two dreams". A university student and former RDHK radio host Christina Chan wrapped the Tibetan snow lion flag around her body and later began waving it. Several onlookers heckled Chan, shouting "What kind of Chinese are you?" and "What a shame!" In the end, she and some of the protesters were taken away against their will by the authorities via a police vehicle "for their own protection." Chan is currently[when?] suing the Hong Kong government, claiming her human rights were breached. (case number HCAL139/08)
This group wanted accountability for what 1989 event?
A: Tiananmen Square protests

In 2010, there were concerns among Tajik officials that Islamic militarism in the east of the country was on the rise following the escape of 25 militants from a Tajik prison in August, an ambush that killed 28 Tajik soldiers in the Rasht Valley in September, and another ambush in the valley in October that killed 30 soldiers, followed by fighting outside Gharm that left 3 militants dead. To date the country's Interior Ministry asserts that the central government maintains full control over the country's east, and the military operation in the Rasht Valley was concluded in November 2010.

Most clothing appears to have been made of animal skins, as indicated by finds of large numbers of bone and antler pins which are ideal for fastening leather. Wool cloth and linen might have become available during the later Neolithic, as suggested by finds of perforated stones which (depending on size) may have served as spindle whorls or loom weights. The clothing worn in the Neolithic Age might be similar to that worn by Otzi the Iceman, although he was not Neolithic (since he belonged to the later Copper age).
What famous figure of the Copper Age wore clothes similar to the Copper age?
A:
unanswerable
