  • Fossils: The Evolution Of Modern Humans

    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…

  • Recombinant Dna Synthesis

    landmass formation in the Southern Hemisphere that separated toward the end of the Paleozoic Era, which led to the configuration of South America, Africa, Antarctica, and Australia. Laurasia was composed of what are now North America, Greenland, Europe, and Asia. Tethys ocean was the body of water that lay between the Gondwana and Laurasia split. Gymnosperms are plants with seeds that are not enclosed by an ovary and angiosperms are fruit-bearing plants known for having ovules develop within an…
