A scientist discovers a fossil of a new organism and places it in the fossil record. The fossil shows the organism had similar structures to organism X, which appears later in the fossil record. Which conclusion about the organisms is most reasonable? (1 point)
The fossils are from organisms that lived in the same location.
The fossils are from an organism that is an ancestor of organism X.
The fossils came from the same organism.
The fossils are from an organism that is a descendant of organism X.

The most reasonable conclusion is that the fossils are from an organism that is an ancestor of organism X. This is because the fossil shows similar structures to organism X, indicating a possible evolutionary relationship between the two organisms.

In three to five sentences, explain how the fossil record provides evidence for the idea of natural selection.
The fossil record provides evidence for natural selection by showing the gradual changes in species over time. Fossils reveal the evolution of different species by displaying intermediate forms that showcase the transition from one species to another. The presence of transitional fossils, such as the Archaeopteryx, provide clear evidence of the evolutionary process and the development of new traits in organisms. By studying the fossil record, scientists can observe how certain traits became more prevalent in a population over time, supporting the idea that organisms with advantageous traits are more likely to survive and pass on those traits to future generations through natural selection.
