Unit 8 Reflection


This Unit was about evolution and how things affect a population over time. Natural selection is a tool of evolution and it changes the allele frequency of a gene pool. Natural selection favors certain traits and those are passed on to offspring. Darwin said that there are winners and losers and the population starts to look like the winners. 
This was demonstrated in the Bird Beak Lab. Speciation is the rise of 2 or more species from 1 existing species. This can be caused by behavioral isolation, as seen from the Hunger Games Lab when knucklers only wanted to mate with other knucklers, geographic isolation, and temporal isolation. There is a lot of proof of evolution such as vestigial structures, which are the evolutionary leftovers of ancestors and fossils which are a big piece of evidence. Fossils can do relative dating, homologous structures, and analogous structures. The earth is extremely old and amino acids have been found in meteorites giving the idea that RNA monomers have been made spontaneously from molecules. 
I want to learn more about the proof of evolution and other theories because it is like solving the mystery of time and there are many creative theories. How did we gather this information about the different eras and epochs from fossils? I wonder about how much time the earth was empty and what the development of humans looked like. What are the drastic events that led to life on land, plants, and everything else. 

 I was ranked as being assertive, but I need to fix my collaborative skills.  It's much better once everyone gets involved in a project, rather than one person taking control and making everyone do their tasks. It is very important to find a perfect blend of being assertive, but also being a good leader, and making sure everyone feels that their ideas are felt.
