en kraniestudie av hominider ur ett evolutionistiskt perspektiv
By examine plastic craniums from eight different hominids I wanted to find morfological characteristics that agreed with those of modern humans. The species that were selected had a plastic casting of its cranium in the laboratory at Gotland University. My focus was on species from the family Australopithecius and Homo and only working with their craniums. And this because the cranium and the theeth shows the most visible morfological characteristics between the different hominids. I also wanted,in a small part of the essay, to write about the differences in now living primates and humans skulls.Except from analysing the plastic castings I also studied surveys written by other scientist on the same subject. And in that chapter write as much about the whole skeleton as possible, eventhough that was not my main field, but I wanted to give the readers an overview of the species before the analysis took place.The most visible morfological characteristics is shown in the theeth because the diet changed during the million years that the evolution took place. It is possible to see the development in Foramen magnum too, the hole at the base of the skull were the vertebrate connects with the cranium. This hole gets more central over time showing that the species got more biped and started to walk upright on two legs just like humans do today. There are of course many more characteristics that are able to be seen that seperates us from the extinct hominids, but many of them are the same. If you look closely at the different craniums you can see how the fantastic evolution formed humans out of apes.It has to be mentioned that the scientist have many different theoris about the evolution, the species and who are the real ancestors to humans and I think the disagreement will continue for many years to come.
