Problem: Middle Ages:

Between the 5th and 8th centuries, new peoples and individuals filled the political void left by Roman centralised government. The Ostrogoths settled in Italy in the late 5th century under Theoderic (d. 526) and set up a kingdom marked by its co-operation between the Italians and the Ostrogoths, at least until the last years of Theodoric's reign. The Burgundians settled in Gaul, and after an earlier realm was destroyed by the Huns in 436 formed a new kingdom in the 440s. Between today's Geneva and Lyon, it grew to become the realm of Burgundy in the late 5th and early 6th centuries. In northern Gaul, the Franks and Britons set up small polities. The Frankish Kingdom was centred in north-eastern Gaul, and the first king of whom much is known is Childeric (d. 481).[G] Under Childeric's son Clovis (r. 509511), the Frankish kingdom expanded and converted to Christianity. Britons, related to the natives of Britannia modern-day Great Britain settled in what is now Brittany.[H] Other monarchies were established by the Visigoths in Iberia, the Suevi in north-western Iberia, and the Vandals in North Africa. In the 6th century, the Lombards settled in northern Italy, replacing the Ostrogothic kingdom with a grouping of duchies that occasionally selected a king to rule over them all. By the late 6th century this arrangement had been replaced by a permanent monarchy.

Problem: Mammal:

Mammals include the largest animals on the planet, the rorquals and other large whales, as well as some of the most intelligent, such as elephants, primates, including humans, and cetaceans. The basic body type is a four-legged land-borne animal, but some mammals are adapted for life at sea, in the air, in trees, or on two legs. The largest group of mammals, the placentals, have a placenta, which enables feeding the fetus during gestation. Mammals range in size from the 3040 mm (1.21.6 in) bumblebee bat to the 33-meter (108 ft) blue whale.
