Scientific Theories Of Evolution

Introduction: History of the life on Earth shows species gain new traits as they evolve. Evolution is a development over time in response to the environment. Evolution is a scientific theory. Some evidence scientists have in order to prove this theory are fossils, homology, analogy, vestigial structures and embryology. The purpose of measuring these skulls is to show how our ancestors have evolved over the years. .

Hypothesis: If the skull has similar measurements as the homosapien, then the organism is most likely bipedal.

Variables:
Dependent- The skulls
Independent- the measurements of the skull

Materials:
Protractor
Caliper
The eleven skull models we used
Pencil
Graph to record measurements

Procedure:
Gather all your materials …show more content…
To get the maxillary angle, you lay the skull on its side on the table
You then use the protractor and measure the angle made by the Nasion, Maxilla and the Socket.
You then find the height, width and length of the skull using a caliper
You then find the cranial captivity by Multiplying the length by width by height then you multiply by .5236
