Life changes over time for many reasons. My connection to life is how cars evolved. I chose it because cars have made drastic changes over the past few decades. It applies to common ancestry because all cars had one ancestor to start it. There is evidence of evolution because cars started with horses and now we have engines. A new species of car could be a electric car vs a diesel truck.
This photo is of a Tesla Cybertruck. This car is an electric vehicle with modern features. Completly opposite of the horse drawn buggie
Common Ancestry
All living things started somewhere and branched off and held on the that first ever trait. Earth started as one big ball of molten rock. Once the oceans formed we had tiny organisms living near geothermal vents. Which was called LUCA. We know that LUCA is the bottom of our phylogenetic tree because of what LUCA stands for. organisms on a phylogenetic trees all have at least 1 common trait. To be alive an organism has to consist of organization, metabolism, reproduction, growth and development, response to the environment, and evolution.
My connection is how cars evolved. All cars basically sprouted from the horse drawn buggy. Then Henry Ford created the still known car brand today FORD. Which branched off into vans, SUV's, trucks, and so on. All with the same purpose of getting you somewhere with more efficiency

Recipe for evolution
Evolution happens with time, selection, and so much more.
Things that are needed for evolution are common ancestors, populations, adaptations, natural selection, mutations, Survival of the fittest. There is artificial selection, which is chose specifically to get exactly what is wanted. There is also natural selection which happens in nature and is random with no specifics. Also extinction is needed because new spices need to be created and to make differences in life/evolve.
Some factors for cars to evolve are new technology, higher intelligence, efficiency, popularity, and extinction. There is also opportunities for cars to change. People can choose exactly what they want for their car making modifications like paint color/wrap. There are also things they have no control over, like size of the body and horsepower. Also a car that has gone "extinct" is the Monza Spider, and now their are new cars that didn't use the traits of that car to be more successful.

New Spiecies
New species evolve with time, separation, etc. We proved how to get a species with our butterfly lab. We had hunters and hiders which represented how the life cycle works in real life. Also within that lab we had gotten introduced to allele frequencies. Allele frequency is the number percentage of the living variation of a species. Like my red butterflies ended up with a 0.16 frequency. Separation is needed to create a new species. For example peripatric separation is when a small chunk of a population is separated from the rest. Like when the finches were blown over to a separate island causing them to cross breed to make something new. For a new species to be declared new 10,000 generational years needed to have passed.
The hunters and hiders of cars are like buyers and sellers. The buyers scope out for what they want and buy it from the dealership taking it away from them. The dealership puts cars out for "hunters" to come get. We can represent allele frequency with how many of the make or model have/haven't been bought. Also cars get separated like the Volkswagen is made in Germany allowing new, fresher models to be made while the older ones are being sold in Germany and elsewhere.
This is an image of a Voltswagen Beetle which this is an older model which sold very well while new versions were being created
Human Evolution
Humans have the same evolution idea as do all other organisms. Humans started from what we know as Lucy. Lucy was our original common ancestor with proof of the first organism to walk vertically. (common gene). Humans slowly got less hairy, bigger brains, and walked only vertically, giving proof we evolved from Lucy. We became a new species from Ardipithecus. They were one of our early ancestors on our phylogenetic tree but on a different branch than what we are.
Like humans cars evolved too. For example the first car with a gas engine was the Ben's Patent Motorwagen. This car was shaped/built like a tricycle but larger and had room for my passengers. The automobile's engine was located in the back of the vehicle instead of the front of how we know it now. Our cars now are normally fully enclosed. The Motorwagen was just a seat engine and wheels.

To conclude I think the best/most important thing I learned about this unit was human evolution. I understand more of how phylogenetic trees work and how there is one common trait on every tree. How did Lucy "decide" to walk vertically. I think I could improve my notebook by writing more thoroughly and using color.
I could start writing my notes like this to make important details to stand out making it more memorable.
