Problem: Molecular studies based on DNA analysis have suggested new relationships among mammal families over the last few years. Most of these findings have been independently validated by retrotransposon presence/absence data. Classification systems based on molecular studies reveal three major groups or lineages of placental mammals- Afrotheria, Xenarthra, and Boreoeutheria- which diverged from early common ancestors in the Cretaceous. The relationships between these three lineages is contentious, and all three possible different hypotheses have been proposed with respect to which group is basal with respect to other placentals. These hypotheses are Atlantogenata (basal Boreoeutheria), Epitheria (basal Xenarthra), and Exafroplacentalia (basal Afrotheria). Boreoeutheria in turn contains two major lineages- Euarchontoglires and Laurasiatheria.
During these Molecular studies, which three major groups of mammals shared a common ancestors from the Cretaceous period?

Answer: Afrotheria, Xenarthra, and Boreoeutheria


Problem: After the Partisans managed to endure and avoid these intense Axis attacks between January and June 1943, and the extent of Chetnik collaboration became evident, Allied leaders switched their support from Draža Mihailović to Tito. King Peter II, American President Franklin Roosevelt and British Prime Minister Winston Churchill joined Soviet Premier Joseph Stalin in officially recognising Tito and the Partisans at the Tehran Conference. This resulted in Allied aid being parachuted behind Axis lines to assist the Partisans. On 17 June 1944 on the Dalmatian island of Vis, the Treaty of Vis (Viški sporazum) was signed in an attempt to merge Tito's government (the AVNOJ) with the government in exile of King Peter II. The Balkan Air Force was formed in June 1944 to control operations that were mainly aimed at aiding his forces.
From whom did Allied leaders switch their support from to Tito?

Answer: Draža Mihailović


Problem: However many early history books like the Islamic Conquest of Syria Fatuhusham by al-Imam al-Waqidi state that after the conversion to Islam Muawiyah's father Abu Sufyan ibn Harb and his brothers Yazid ibn Abi Sufyan were appointed as commanders in the Muslim armies by Muhammad. Muawiyah, Abu Sufyan ibn Harb, Yazid ibn Abi Sufyan and Hind bint Utbah fought in the Battle of Yarmouk. The defeat of the Byzantine Emperor Heraclius at the Battle of Yarmouk opened the way for the Muslim expansion into Jerusalem and Syria.
Who was the Byzantine leader at the Battle of Yarmouk?

Answer:
Heraclius
