In three to five sentences, explain how the fossil record provides evidence for the idea of natural selection.

Answered by GPT 3.5
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.

"Hominins" is the correct answer as it includes only bipedal animals.

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.
