Unit 8 Reflection

This unit was about evolution and what goes into a population evolving. Within a population, there are different traits which are called variation. When artificial selection occurs, that is when humans want a specific trait in an animal, that can create a new species overtime. Charles Darwin was an expert about evolution and natural selection. From the observations he made, he conjectured two conclusions: 1) The fittest win and 2) Populations look like the winners. Natural selection is a factor of evolution, which is a process of using the winners of the populations and passing their traits to their offspring to survive. We simulated a species in the real world and how the chances that they survive with different traits. You can read about it here. The gene pool is the sum of variation in a species. Species is a group of individuals that can reproduce and have fertile offspring. Speciation is the formation of new species, and it is caused by reproductive isolation. Evolution is a theory, and every theory has evidence: developmental evidence, vestigial structures, fossils, homologous structure, and analogous structure. Population contains natural selection that can change the distribution of a trait. The formation of the Earth started with chemical and physical processes. The Earth's history was broken into four eras, the era we live in now is the Cenozoic Era.

I love the topic of evolution, but we haven't applied it to us, humans. I'd really like to learn more about homo sapiens and how we came to be. The mysteries of animal and human evolution is so fascinating, like how wolves evolved from whales.

As stated in the last unit reflection, I am a passive-assertive person. A person of that kind will let you walk over them to a certain extent. Our goal is to be an assertive person, hopefully not offending anyone during that path. I've been working on my confidence, although it will take a long time. I noticed that I hide behind my friends when confronting others and during projects, don't express my personal opinion. I'm mostly afraid that they won't accept me and think my ideas are dumb. I see myself inferior from others and that is what is keeping me from my goal. A start would be to stand up for my opinions.

It's coming to an end: 20-Time Individual Refelction

Image
A recap of what my project is all about: I decided to host two different cleanups. One was a beach cleanup at Capitola Beach last Friday, May 19th, and the other was a county wide river cleanup on Saturday, May 20th. I chose idea after countless of other failed attempts for this project. I wanted to impact the bay area, and besides having cleaner beaches and rivers, the main goal was to educate students about the importance of clean bodies of water and be one step closer to a pure environment. Below are the flyers I made for the two events to get the word out. My initial plan for this project is not the plan I ended up doing. If you look back on my last few post about my 20-Time, they've been changing since day one. When I finally settled down on this idea, its was already the midway point of the project. For the goal of my project, I knew that if I wanted it to be successful, I'd have to spread the word out, hence the flyers. I wouldn't call this whole experience su

Poor Piggy: Pig Dissection Lab

Image
In replace of a video, I decided to write about it instead of show it. External Anatomy: Usually, the fetal pig is a light beige/ off pink color. To dissect it, you must tie down the wrists on the plate to have the ventral area exposed for dissection. The wrists of the pig is cut out of the diagram, but just like humans, it would be located near the ends of the arm. The shoulder is spread openly, which can be found after the elbow of the arm. Digits are essentially the fingers and toes of a pig. They are connected to the wrist, at the end of the arm. Those two structures allow the pig to move. The thoracic cavity is everything from the diaphragm and up. We'll talk about what goes into that portion of the pig later. The abdominal cavity should be everything below the thoracic cavity. To determine the sex, you look at the urogenital opening. On males, it should be located near the umbilical cord. For females, the opening is near the anus. Digestive System: In a digestive sys
