Dendrochronology

The picture above was supplied in class from a recently cut down tree. By simply counting the tree rings that appeared as the tree went through its growing cycles, the approximate age of the tree can be determined. Although not precise, I counted 67 rings in this tree which means it has seen some history while in Macon. Although not Georgia related, this means that the tree has been around while the Florida Gators football team has won 9 conference titles, 3 National championships, and appeared in 40 bowl games. The basketball team has also won 9 conference regular season titles, 4 conference tournament titles, appear in 4 final fours, and win 2 National championships.

Mitochondrial Eve

Mitochondrial Eve is a general population that all humans come from and is located in northeast Africa. The concept that one hundred percent of mitochondrial DNA comes from the maternal line allows scientist to trace human lineage all the way back to this single Mitochondrial Eve.

The diversity of the human race in modern times can sometimes create the sense that humans are all different. Mitochondrial Eve, however, can prove that the distinctions we see today are just transformations that took place due to the environment that people moved to.

The following pictures show just how much the different regions have allowed humans to transform over the thousands of years.

Maps

Dot Density: These maps place single dots as data points on a regional map. As the dots continue to be added, the locations that contain more points clearly become denser and darker,

Chloropleth: This type of map sets each region to a certain color in order to distinguish certain data locations. In the example below, the darker the county, the more Hispanics that live in that county.

Isarithmic: This map is similar to the chloropleth map except the colored regions are not bounded by predetermined regions but rather based on statistical data alone.

Proportional Symbol: These maps place the same symbol in each region but use the size of that symbol as the indicator of the data.
