How should the fossils in the sediment layers of Earth appear if species have evolved over time?
Idk why should I care??
The most recent ones on top so you find them first. Lots of things can go wrong with that though :)
If species have evolved over time, the fossils in the sediment layers of Earth should appear in a specific pattern called the fossil record. Here's an explanation of how the fossil record should look if species have evolved:
1. Law of Superposition: The law of superposition states that in undisturbed layers of sedimentary rocks, the oldest rocks are at the bottom and the youngest rocks are at the top. So, the deeper you dig into the sediment layers, the older the fossils you'll find.
2. Transitional Fossils: If species have evolved, there should be transitional fossils that show a combination of characteristics from different species. These fossils act as evidence for the gradual changes that occurred over time. For example, if a land-dwelling mammal evolved into a whale, there should be fossils that show intermediate stages with features of both land mammals and whales.
3. Chronological Order: The development of new species should follow a chronological order in the fossil record. This means that fossils of simpler organisms should be found in lower, older layers, while more complex organisms should be found in higher, younger layers. For instance, fossils of single-celled organisms should be found in deeper layers, while fossils of complex multicellular organisms, like mammals, should be found in higher layers.
4. Extinction Events: Throughout Earth's history, there have been several mass extinctions that wiped out a significant number of species. These events should be reflected in the fossil record. You would see layers where certain groups of fossils suddenly disappear and new ones appear after the extinction event.
By studying the sediment layers and the fossils they contain, paleontologists can analyze the patterns, transitional forms, and chronological order of fossils to support the theory of species evolving over time.
It is evolution, because we all have some of the same traits like eye color or shape or ears.

Use this one, I fixed the grammar.
