Unit 8 Reflection

In this Unit, Unit 8, we were taught about evolution. The major themes and understandings to help us better understand evolution was Natural and Artificial selection, the 4 different types of isolations, being reproduction isolation, geographic isolation, behavioral isolation, anat one extremed  temporal isolation. We were also taught about the different selections, being Directional selection which favors phenotypes, stabilizing selection which favors the intermediate phenotype, and disruptive selection which favors both extreme phenotypes.

In this unit I would like to learn more about why a species ant reproduce with each other after going through geographic isolation. I have one unanswered question which is if earth is 4.6 billion years old then how old is the universe? I wonder what the max of how many times a species evolved before the species went extinct? An example of when I was assertive is when I beat this guy in basketball and he still said he was better then me and was really annoying me and making me angry and instead of saying your the worst and stuff like that, all I said was ok maybe next time you will beat me ad then I just walked a way. But I can definitely be more assertive by being more respectful when angry.
