From the past few decades to this day, one of the most controversial and heavily researched topics in the scientific and paleontological fields is the evolution of fade beings. New excavations and reconstructions constantly bring new evidence to retread the human ancestral tree. Today, it is widely accepted that humans assist a common ancestor with the primates and that we withdraw evolved from any(prenominal) primate closely related to our fresh day primates. Scientists, with todays technology, ar able to reconstruct comp allowe skulls of ancient hominids from just fragments of the real skull - like a persona of a mandible, for example. In this science laboratory it was out job to analyze these models and create out let evolutionary tree based on our findings. Â Â Â Â Â Â Â Â The following is my abbreviation of the 11 specimen we were presented with. I have organized them by genus and in each genus by evolutionary chronology - the archetypal evolved first -year and the most evolved last. Â Â Â Â Â Â Â Â Igium Magnus (Large Ridge) The species in this genus are characterized by the sagittal prime of life that runs along the midline of their frontal and parietal bones. This genus is the ancestor for the modernistic day orangutan, which is also displays the crest, protruding maxilla, and exaggerated eyes. Skull #61 was piece in Kenya and is dated 2.5 million years ago. The black populate of color is due to high manganese content, I assume, in the story it was excavated from. The skull shows a prominent sagittal crest test from the parietal bone back (white).
It is characterized by its widely afire(p! ) zygomatic processes (red) and its high degree of prognathism (green). The orientation of the skull, mainly the slant of the portray to the cranial cavity, along with the placement of the foramen magnum towards the occipital, quite than more centralized, suggest that this... bully work, this is an incredibly scientific essay. You have shown great sympathy and knowledge in this particular topic. Its salutary written and structured. Great essay for human evolution- well done.
