The discovery and observations of fossils have led us to a lot of conclusions of where modern humans come from (Larsen 2008). Fossils are very significant because they are pieces from the past that provide us with evidence of organisms that were once alive (Larsen 2008). The three hominins that I’ll be comparing are Sahelanthropus tchadensis, the Australopitheicus afarensis, and the Homo neanderthaleasis. This gives us a wide range to compare from really early on to a more recent hominins that eventually leads to modern humans. Comparing the brain size of this 3 species is very interesting because it allows us to see the evolution of how much growth and adaptation the cranial part and therefore the intelligence level of this species has done leading up to modern humans. It also shows us the immense brain capacity modern humans have, therefore becoming the species with the biggest brain for our body size. The Sahelanthropus tchadensis is one of the oldest, if not the oldest hominin specie that we have in the primate fossil record (Larsen 2008). Being approximately 7 million years old, there’s minimal fossils found for it, being mostly represented by a skull (Zollikofer, Lieberman, Frank 2005). The cranium is very important when studying systematics and behavioral characteristics in these individuals (Zollikofer 2005). The reconstruction of the cranium, which had suffered fractures and deformation confirm that S.tchadensis is a part of the hominid group and not as related to…
