The first chapter covers the beginnings of life up to the Cambrian Explosion. In the very beginning of Earth's creation, there was almost nothing but extreme weather and lava and boiling oceans. These oceans contained lots of organic chemicals, and we call this the "primordial" soup. Eventually, these joined together to create neucleotides and amino acids that eventually (after thousands of years) formed cells that further evolved (after millions of years) into the beings that walk the earth today.
The two types of cells are prokaryotic and eukaryotic. Prokaryotes are very basic and mostly single celled organisms. Examples of prokaryotes include bacteria and archaea bacteria. Eukaryotes are more complex and mostly multi-cellular organisms. Eukaryotic creatures are special because they have a nucleus in their cells that directs all of the other organelles. Plants, animals, and fungi are all eukaryotic.

evolution comic prologue review
The prologue of this comic series talked a lot about natural selection and gave an overview on the beginnings of evolution. I learned that natural selection is the process in nature in which the most favorable traits are passed on to a species offspring.These arise through mutations in the cell that give the organism an advantage in its changing surroundings. In order for natural selection to occur these things need to happen: (1) there needs to be variation in certain traits of a population, (2) not all organisms can survive to reproduce offspring and pass on their traits, (3) survival cannot be random, and (4) the favorable traits must be heritable.

8/31 writing about my weekend
On Friday, I went to the MHS vs FPC football game. I was a little late to call time, but we still ended up getting there before the game started. It was a lot of fun! We cheered and played stand-tunes throughout the first half of the game. During halftime, we performed our show right before getting rained on. So as an alternative, we went to the FPC gym and hung out with their band. When we went back out in the 4th quarter, we were winning the game! The end score was 14-7, and it was the first time MHS has won a rival game against FPC.
