Answer:
M.Leakey was a paleoanthropologist of no formal university education and British origin. Her major discoveries were;
1. the proconsul skull
2. Zinjanthropus skull at Olduvai Gorge In Tanzania
3, system of classification of discovered stones.
4.Laetoli footprints at Laetoli sites.
However, her most outstanding discoveries were proconsul skull ( projecting face with no browridges, and presence of ape-like teeth shapes) and the Laetoli prints. She believed the skull belonged to ancestral Homo habilis, which could be traced to origin of mankind.
The discovery of Laetoli prints showed evidences of bipedalism and the origin of Australopithecus. These prints and the skeletons she unearthed proved that the ancestral of human race actually walked upright, nearly four feet tall in height.Hence she concluded that these prints actually belong to the Australopithecus. This brought a paradigm shift in modern understanding of human evolution of prehistoric times and the origin of mankind,
Her discoveries generally throw light on the <u>evolution of mankind </u>and new understanding of <u>genesis of human race</u>

Answer:
The ultimate level of causation refers to the behavior’s evolutionary significance; how the behavior enhances reproductive fitness. The proximate cause refers to the immediate cause of a behavior, whether that be hormonal, neurological, cognitive, interpersonal, or cultural. For example, the proximate cause of humans eating more cookies, cake, and ice cream involves the psychological tendency to desire and enjoy foods with high sugar and fat content. The ultimate cause involves the high caloric content of both sweet and high fat foods, which promotes physical survival in resource-scarce environments.
