The hominid that is described is <em>Australopithecus africanus</em>.
<em>Australopithecus africanus</em> is one of the extinct hominids. It lived approximately from between 3.2 to 2.1 million years ago, in the late Pliocene and early Pleistocene. It is a species that lived in Africa, but its total range is not well known as there is only four fossils from it found, all in the same region, in the southern part of Africa.
The <em>Australopithecus africanus</em> is thought to be the ancestor of the later <em>Homo habilis</em>, and it is also considered to be a direct ancestor of the modern <em>Homo</em> <em>sapiens</em>, though that is still debatable.
Answer:
Because a stationary front marks the boundary between two air masses, there are often differences in air temperature and wind on opposite sides of it. The weather is often cloudy along a stationary front, and rain or snow often falls, especially if the front is in an area of low atmospheric pressure.
This is still a reliable source because it clearly cites scientific research. Sometimes sources flatly contradict a given statement, study or an existing fact. In that case, there are things that we need to consider like the source of the evidence, is there outside evidence that supports one of the sources, and how do the conflicting sources fit with other existing facts present about the topic.
