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.
When did the division of the eight main groups of angiosperms occur?
40 million years ago

Many Islamic anti-Masonic arguments are closely tied to both antisemitism and Anti-Zionism, though other criticisms are made such as linking Freemasonry to al-Masih ad-Dajjal (the false Messiah). Some Muslim anti-Masons argue that Freemasonry promotes the interests of the Jews around the world and that one of its aims is to destroy the Al-Aqsa Mosque in order to rebuild the Temple of Solomon in Jerusalem. In article 28 of its Covenant, Hamas states that Freemasonry, Rotary, and other similar groups "work in the interest of Zionism and according to its instructions ..."
What are most of the arguements by anti-masonic muslims centered on? 
antisemitism and Anti-Zionism

Some "popular" genre musicians have had significant classical training, such as Billy Joel, Elton John, the Van Halen brothers, Randy Rhoads and Ritchie Blackmore. Moreover, formal training is not unique to the classical genre. Many rock and pop musicians have completed degrees in commercial music programs such as those offered by the Berklee College of Music and many jazz musicians have completed degrees in music from universities with jazz programs, such as the Manhattan School of Music and McGill University.
Rock and pop musicians may have degrees in what type of music?
commercial
