Excerpts from the Paper

The beginning:
Skull Size in Relation to Intelligence Over Time (Evolution)
The following paper outlines a recent excursion to Redpath Museum (at McGill University) whereat this writer reviewed several skulls that appear to depict a general increase in cranial size amongst human beings over time. The paper will then discuss how the literature appears to suggest that cranial size is intimately connected with a general increase in human intelligence over the millennia. We may thus surmise that evolutionary upswings are the product of human beings gradually – presumably through natural selection or via better nutrition – and steadily developing increased intellectual capacity as their brains grow in size and as their skull cases increase in size...
The end:
.....nue to evolve – for humanity is not done changing just yet. At the end of the day, brain size does appear to correlate to the ability to manipulate and control the natural environment and the resources at our disposal. Without such evolutionary growth, we might well have fallen prey to extinction as have other species that lacked our capacity for higher-level cognition and our capacity to adjust to a dynamic world.
