When Richard Potts, an expert in ancient environments, reviewed evidence about the environment in which Ardipithecus ramidus would have lived at Aramis and Gona, he concluded that the sites:.

The sites indicated variability in the proportion of grass versus trees

Explanation:Ardipithecus ramidus is a hominin species dating to between 4.5 and 4.2 million years ago (mya) using paleomagnetic and radioisotopic dating methods. (Paleomagnetic uses periodic reversals in the Earth’s magnetic field; radioisotopic utilizes the known rate of decay of one radioisotope into another) Importantly, Ar. ramidus represents the oldest species that possesses features unequivocally linked to the hominin lineage. Thus, Ar. ramidus is the best evidence discovered thus far for the root of the hominin family tree. Fossils of this species, found in the Middle Awash region and the site of Gona in Ethiopia, possess derived features (features different from those found in the ancestor) in the skull and teeth.

an empire is a sovereign state functioning as an aggregate of nations or people that are ruled over by an emperor or another kind of monarch. the territory and population of an empire is commonly of greater extent than the one of a kingdom.[1]

an empire can be made solely of contiguous territories, such as the austro-hungarian empire or the russian empire, or of territories far remote from the homeland, such as a colonial empire. aside from the more formal usage, the word empire can also refer colloquially to a large-scale business enterprise (e.g. a transnational corporation), a political organisation controlled by a single individual (a political boss), or a group (political bosses).[2] the word empire is associated with such other words as imperialism, colonialism, and globalization. empire is often used to describe a displeasure to overpowering situations.[3]
