Lab #8 Darwin's Dilemma

The video explores Darwin's dilemma which was that his theory of gradual evolution is not supported by the fact that the fossils he found seemed to have been formed almost at once.  The evolution was not gradual but rather sudden and is called the Cambrian Explosion. The duration is not known and it raises huge questions, it could have lasted from one day to many years.  These findings have stirred up massive debate which challenges Darwin's theory.  Southern China seems to have a lot of fossils in mint condition that can be examined, and there are some fossils from before the Cambrian explosion that can help explain how this came about.  Darwin's theory while viable  is not the only one out there and many people adhere to it so that any other theory seems to be pushed to the wayside.  I don't know what to believe anymore. Evolution is still a lot of theory.  "Nature takes no sudden leaps" is a famous quote from Darwin which is being challenged by this
Cambrian Explosion.  It seems some sort of biological catalyst was introduced that jump started all of these species.

Lab #7 Hitchiti Experimental Forrest

Unfortunately I was unable to make it to the Hitchiti Experimental Forrest because of my Spanish test. However me and Jarett were able to drive out there in time to see everyone's car and leave a note on your car Dr. Rood.  And you told us too look up the wild ginger and here are some of the interesting facts that I learned.


Wild ginger is a workhorse of a groundcover, spreading readily with beautifully glossy, slightly heart-shape leaves. It must have shade and moist but well-drained soil to thrive, but with the right conditions this native plant is indispensable, doing well where many other plants wouldn't. In spring it bears purplish maroon bell-shape blooms mostly hidden in the foliage. 
The plant is called wild ginger because the rhizome tastes and smells similar to ginger root, but the two are not particularly related.

Lab # 6 Jackson Spring

Jackson Spring Park is located at 998 Nottingham Drive in the Shirley Hills neighborhood, Macon, Georgia. The land was left to the "white children and women" of Macon from the wealthy landowner who lived in that area.  The land was eventually sold by the city and bought by commercial industries such as an apartment complex and the Kroger that are in the area.  While we were at the park we looked at very many different types of rocks and used a rock to break them open and look inside.  Rocks from the park itself and near the river is what we examined.  Also the sieve was used to examine the creek beds contents.  This helped us examine the different sizes and contents that are present in the creek.  Also it was a little chilly that day.
