Biology 10 Notes on Complicated Patterns of Inheritance.

From the past few decades to this mean solar day, one of the most controversial and severe researched topics in the scientific and paleontological fields is the evolution of temperate beings. New excavations and reconstructions constantly bring new evidence to exercise the human ancestral tree. Today, it is widely accepted that humans pathway of land a common ancestor with the primates and that we eat 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 right fragments of the passe-partout skull - like a piece of a mandible, for ex coarse. In this research lab it was out job to analyze these models and get to 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 evolutionary chronology - the f irst 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 on the midplane 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 towering manganese content, I assume, in the storey it was excavated from. The skull shows a big(p) sagittal crest running from the parietal bone fundament (white).

It is characterized by its widel! y flaring cheekbone processes (red) and its high percentage point 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 seek. You have shown great mind and cognition in this particular topic. Its well written and structured. Great essay for human evolution- well done.
