Problem: The Vedas, the earliest texts on Indian philosophy and Hindu philosophy dating back to the late 2nd millennium BC, describe ancient Hindu cosmology, in which the universe goes through repeated cycles of creation, destruction and rebirth, with each cycle lasting 4,320 million years. Ancient Greek philosophers, including Parmenides and Heraclitus, wrote essays on the nature of time. Plato, in the Timaeus, identified time with the period of motion of the heavenly bodies. Aristotle, in Book IV of his Physica defined time as 'number of movement in respect of the before and after'.
How long ago are the earliest texts of Heraclitus philosophy dated?

Problem: Synnecrosis is a rare type of symbiosis in which the interaction between species is detrimental to both organisms involved. It is a short-lived condition, as the interaction eventually causes death. Because of this, evolution selects against synnecrosis and it is uncommon in nature. An example of this is the relationship between some species of bees and victims of the bee sting. Species of bees who die after stinging their prey inflict pain on themselves (albeit to protect the hive) as well as on the victim. This term is rarely used.
Why do bees sting even though it will kill them?

Answer: to protect the hive

Problem: In early August 2008, Iowa Labour Commissioner David Neil announced that his department had found that Agriprocessors, a kosher meatpacking company in Postville which had recently been raided by Immigration and Customs Enforcement, had employed 57 minors, some as young as 14, in violation of state law prohibiting anyone under 18 from working in a meatpacking plant. Neil announced that he was turning the case over to the state Attorney General for prosecution, claiming that his department's inquiry had discovered "egregious violations of virtually every aspect of Iowa's child labour laws." Agriprocessors claimed that it was at a loss to understand the allegations. Agriprocessors' CEO went to trial on these charges in state court on 4 May 2010. After a five-week trial he was found not guilty of all 57 charges of child labour violations by the Black Hawk County District Court jury in Waterloo, Iowa, on 7 June 2010.
When did the CEO go on trial?
