Summary
There is a lot of evidence for evolution including the fossil record. The fossil record is the history of life documented by fossils. When looking at the fossil record, you can compare different fossils to other fossils that look similar and slightly different to one another. By examining the rock you found the fossil in, you can also get an estimated time and duration of that species life. Once you have found enough fossils of animals that look extremely similar, you can place them in an order that makes sense and see how the particular organism evolved over time. More evidence of evolution can be found in comparative anatomy. For example, when you look at the bones in the arm of a human, bird, dog, and whale, you will see that all of those organisms have a very similar bone structure. This tells us that all of those species are related therefore evolution has occurred.
SP2: Developing and Using Models
I developed a model when I created a poster with my group containing the fossil record for the "adventurian" species. The table included the duration and time that the species lived as well as a picture of what the species looked like. You can use this model as a visual representation of how the species evolved over the years by looking at the pictures of the species and noticing the small changes that appeared. The purpose of this model was to explain how fossil records can be used as evidence for evolution.
XCC: Stability and Change
In evolution, organisms always change and evolve through generations. In our fossil record of the "Adventurian" species, I noticed how in the beginning or first few eras the species didn't really evolve. This must mean that the environment of the species was stable. However, after that, the species started to change a lot. It evolved by growing spikes, legs, changing shape, size, and more. in nature, though it may seem stable organisms are always changing.
