The Cambrian is a major division of the geologic timescale that begins about 541.0 1.0 Ma. Cambrian continents are thought to have resulted from the breakup of a Neoproterozoic supercontinent called Pannotia. The waters of the Cambrian period appear to have been widespread and shallow. Continental drift rates may have been anomalously high. Laurentia, Baltica and Siberia remained independent continents following the break-up of the supercontinent of Pannotia. Gondwana started to drift toward the South Pole. Panthalassa covered most of the southern hemisphere, and minor oceans included the Proto-Tethys Ocean, Iapetus Ocean and Khanty Ocean.
What continent moved to the southern-most part of the earth in the Cambrian era?
****
The answer: Gondwana

In the early stages of the First Punic War (264 BC) the first known Roman gladiatorial munus was held, described as a funeral blood-rite to the manes of a Roman military aristocrat. The gladiator munus was never explicitly acknowledged as a human sacrifice, probably because death was not its inevitable outcome or purpose. Even so, the gladiators swore their lives to the infernal gods, and the combat was dedicated as an offering to the di manes or other gods. The event was therefore a sacrificium in the strict sense of the term, and Christian writers later condemned it as human sacrifice.
How was the gladiatorial combat described?
****
The answer: funeral blood-rite
