Can someone tell me what you would score the following questions from my geol exam? Don't worry you can't help me cheat, I already finished it (and did shit lol). Just feeling nervous.
> Why is the early rock record of the Precambrian rocks more difficult to interpret than the rock record of the Phanerozoic Eon?
The Precambrian era lasted for much, much longer than the Phanerozoic era and the usual methods of analyzing minerals aren't as present, due to the atmospheric makeup of earth at the Precambrian being far different than modern days and lack of fossils besides Cyanobacteria.

>Compare and contrast the Darwin-Wallace mechanisms of natural selection and evolution with Lamarck’s theory of inheritance of acquired characteristics. Explain how both of these concepts might apply to the development of long necks in giraffes.
Darwin-Wallance mechanism for natural selection and evolution involves each generation involves getting longer necks, by having parents of a fitter genetics (which in this case, longer necks) breed with each other. This makes evolution a gradual process, that happens over generations of a species time line
Lamarck's theory of inheritance of acquired characteristics says that the animal would get the needed trait. The giraffes in this case, would develop a longer neck over it's lifetime. This puts the change on the individual, and the giraffes gets a longer neck.
They both share the same principle of adapting to need, but they differ with how the change happens. Lamarck's is within the time scale of an animal's life, while Darwin-Wallaces timescale is within a species's timeline.

I asked chatGPT and it says "um, SWEATY, you didn't go enough detail", kinda stuff, for an intro to geol class. So here we are. ChatGPT says I would get 14/16 respectfully.
