The great angiosperm radiation, when a great diversity of angiosperms appears in the fossil record, occurred in the mid-Cretaceous (approximately 100 million years ago). However, a study in 2007 estimated that the division of the five most recent (the genus Ceratophyllum, the family Chloranthaceae, the eudicots, the magnoliids, and the monocots) of the eight main groups occurred around 140 million years ago. By the late Cretaceous, angiosperms appear to have dominated environments formerly occupied by ferns and cycadophytes, but large canopy-forming trees replaced conifers as the dominant trees only close to the end of the Cretaceous 66 million years ago or even later, at the beginning of the Tertiary. The radiation of herbaceous angiosperms occurred much later. Yet, many fossil plants recognizable as belonging to modern families (including beech, oak, maple, and magnolia) had already appeared by the late Cretaceous.
What is the appearance of a large amount of angiosperms in the fossil record known as?
****
The answer: great angiosperm radiation,

Voting results have been a consistent source of controversy. The mechanism of voting had also aroused considerable criticisms, most notably in season two when Ruben Studdard beat Clay Aiken in a close vote, and in season eight, when the massive increase in text votes (100 million more text votes than season 7) fueled the texting controversy. Concerns about power voting have been expressed from the very first season. Since 2004, votes also have been affected to a limited degree by online communities such as DialIdol, Vote for the Worst (closed in 2013), and Vote for the Girls (started 2010).
When did Vote for the Girls start?
****
The answer: 2010

Later, the constitution was amended to state that the citizens of the 16 states had successfully achieved the unity of Germany in free self-determination and that the Basic Law thus applied to the entire German people. Article 23, which had allowed "any other parts of Germany" to join, was rephrased. It had been used in 1957 to reintegrate the Saar Protectorate as the Saarland into the Federal Republic, and this was used as a model for German reunification in 1990. The amended article now defines the participation of the Federal Council and the 16 German states in matters concerning the European Union.
The amended article 23 now defines the participation of the Federal Council and what else?
****
The answer: the 16 German states
