In this Unit, we learned about evolution, and different factors that go with evolution or effect evolution. Charles Darwin, the one who first discovered the theory of evolution, taught us many things on how evolution really works. For an example, we learned about artificial selection which is when humans select traits and breed for them, this lets humans breed for the traits that are more useful to them, and the population evolves like the human wants it to. We learned about natural selection which is when the population weeds out traits that doesn't help it survive, evolution is caused by natural selection. A way to measure evolution is through measuring the allele frequency in a population. The allele frequency in a population can change as the individuals of the population produce offspring; as the allele frequency changes, the population evolves. Next we learned about speciation, which is the rise of 2 or more species from one existing species, this can happen because of the separation of a population which can create new traits and eventually a new species. We also learned about how life came about to the Earth so many years ago. Life started as very simple cells, then evolved into more complex cells until finally it formed small plants and animals. In a broad scale of time, life has evolved very rapidly on Earth both biotically and abiotically. Finally we learned why evolution really is something that takes place, and what evidence there is to support the theory of evolution. Embryology is something that supports the theory of evolution. It shows that many species have similar stages of embryo development, which suggests common ancestry. 
This Unit was very intriguing, and I learned a lot. Although we have learned about evolution before, I feel like this Unit went much more in depth and I have a much greater understanding. I definitely want to go more in depth in certain aspects such as, the reasons to support evolution. I found it very interesting that species have many things in common including the stages their embryos go through. This Unit was also very fun in that we did some very interesting labs. One lab that I really enjoyed was the Hunger Games Lab. The Hunger Games Lab mimicked what survival would be like in the wild, from fighting for our food, to trying to find a mate. This lab helped me visualize evolution and how it really takes place in nature.
In this Unit we watched a video on how to be assertive. It talked about having good posture and good leadership skills, in order to be more respected wherever you are. I have tried to apply some of these to my daily life by trying to keep good posture, and making direct eye contact with whomever I am speaking to. However I can still work on speaking more assertively, so my voice and opinion is heard and taken seriously wherever I go.
