By 2.5 million years ago, there were at least 2 evolutionary lines of hominins descended from the early australopithecines. One line apparently was adapted primarily to the food resources in lake margin grassland environments and had an omnivorous diet that increasingly included meat.t was there in 1936 that he found the first known adult Australopithecus africanus while excavating in Sterkfontein cave. In 1938, he discovered more fossil remains of africanus and other early hominins in Kromdraai cave. Some of these fossils were larger boned and more muscular with powerful jaws.
A student carrying 12 or more credit hours in a fall or spring semester is considered a full-time student. Other definitions: Freshman: a student who has completed fewer than 30 credit hours. Sophomore: a student who has completed 30 or more credit hours. Part time: a student carrying fewer than 12 credit hours in a fall or spring semester.
In my experience, a student must have at least 60 semester hours prior to classification as a Junior, but this varies for each institution and major.ow many credit hours are needed to become a senior in college and what are the number of credit hours needed for each classification such as freshman sophomore junior senior?
