Based upon the information left with each of the seven skulls, the remains can be identified with the appropriate genus and species. For all seven skulls, Dr. T. C. Musoma left the cranial capacity, location and the artifacts, if any, found with …show more content…
Evolution shapes certain characteristics which can be shared by many species of a certain organism. These traits can be related to the four evolutionary trends of hominins: bipedalism, dental change, cranial capacity and material culture. (Gonzalez, pwpt) The three anatomical characteristics of skull one are the teeth and jaw are smaller, the projection of the face and jaw is less than previous hominins and the cranial capacity increases by elongating. The dental change suggests a change in diet from being herbivores to being omnivores because of environmental changes. The changes in the prominence of the face and jaw is due to evolution choosing the species to be bipedal. The cranial capacity increases which allows the capacity to have a materialistic culture. The slight projection of the face and jaw, a large cranial capacity and large nasal feature are the anatomical characteristics of skull two. Evolution chooses the slight projection of the face because the species is bipedal. The large cranial capacity allows for the culture of Homo sapiens neandertalensis to become more materialistic. Also, the increase of cranial size provides the capacity to create and use tools. The large nasal feature on the skull is an evolutionary adaptation due to the cold environment the species lived in. The anatomical characteristics of skull three …show more content…
The second theory of “Out of Africa” involves Homo sapiens (archaic) leaving African and replacing most populations of Homo erectus in Europe and Asia. Homo sapiens sapiens left Africa and spread into the rest of the world which brought about the third theory of “Out of Africa.” The evidence for and against the theories of Out of Africa have been developed throughout time. The increase in bipedalism due to the anatomical changes to the skeletal build of each species supports each theory. Also, the changing environments and diet of each species support the theories of “Out of Africa.” Through research, there is little evidence against the theory of “Out of Africa.” According to Dr. Katarina Harvatia, the genetic diversity of the species who left Africa wouldn’t have evolved as quickly as timeline presents which goes against the theory of “Out of Africa.” (Harvatia, Mysterious
