Biology 10 Notes on Complicated Patterns of Inheritance.

From the past few decades to this solar day, one of the most controversial and grueling researched topics in the scientific and paleontological fields is the evolution of tender-hearted beings. New excavations and reconstructions constantly bring new evidence to crook the human ancestral tree. Today, it is widely accepted that humans separate of land a common ancestor with the primates and that we relieve oneself evolved from somewhat primate closely related to our ultramodern day primates. Scientists, with todays technology, ar able to reconstruct complete skulls of ancient hominids from on the button fragments of the passe-partout skull - like a piece of a mandible, for ex huge. In this research lab it was out job to analyze these models and establish out bear evolutionary tree based on our findings.         The following is my analytic thinking of the 11 specimen we were presented with. I have organized them by genus and in each genus by evolutiona ry chronology - the first off evolved first and the most evolved last.         Igium Magnus (Large Ridge) The species in this genus are characterized by the sagittal peak that runs along the midline of their frontal and parietal bones. This genus is the ancestor for the modern day orangutan, which is similarly displays the crest, protruding maxilla, and exaggerated eyes. Skull #61 was bring in Kenya and is date 2.5 million years ago. The black colouration is due to spicy manganese content, I assume, in the storey it was excavated from. The skull shows a vainglorious sagittal crest running from the parietal bone anchor (white).

It is ch! aracterized by its widely flaring cheekbone processes (red) and its high story of prognathism (green). The orientation of the skull, mainly the angle of the prospect to the cranial cavity, along with the placement of the foramen magnum towards the occipital, rather than more than centralized, suggest that this... ample work, this is an incredibly scientific screen. You have shown great mind and noesis in this particular topic. Its well written and structured. Great essay for human evolution- well done.
