Unit 8 Reflection

Hunger Games Lab

   In this unit we learned about how over time artificial and natural selection cause evolution, and also how this evolution is shown and how it can be proven. In the Change, It's all natural and Very Gradual Change you can believe in vodcasts we learned how both natural and artificial selection over time cause a population to evolve. The swimming in the gene pool vodcast explained how this evolution happens over time more statistically by showing allele frequencies and population numbers. We later simulated this process in the hunger games lab in which natural selection played on a population causing the population to have a higher allele frequency of the allele that resulted in a beneficial phenotype. The speciation vodcast explained how a species splits into 2 different species because of behavioral, geographic, or temporal reasons. Evidence for evolution can be shown in embryology, vestigial structures (evolutionary left overs like the human tailbone), Fossils, homologous structures (same structure of bones but different function), or in analogous structures which is the opposite of homologous structures. And finally the origin of life vodcast the possible theories for how life first formed are explained.

    I would like to learn more about the causes and effects of evolution over time and the specific species that where created and how they came to be. This unit was very full of information and left me with no unanswered questions. I wonder about what species existed on earth before and later when extinct and how some of their traits are shown in our modern species.

    In the Unit 7 Reflection I reflected on the topic of being assertive. We watched a video and did a survey on how assertive I am. Most of the points I got on the survey showed that I was assertive. Over this unit I have kept being assertive and helpful in our timeline project.
