The fossil record provides evidence for the idea of natural selection by showing how species have changed over time. Fossils from earlier time periods show organisms with traits that differ from modern day organisms. Some of these traits may have provided an advantage for survival, allowing those individuals to reproduce and pass on their advantageous traits to their offspring. As time goes on, we see that these advantageous traits become more common in a population, indicating that natural selection has taken place.
The fossil record provides evidence for the idea of natural selection by showcasing the gradual changes in species over time. Fossils preserved in different layers of rock reveal a progression of life forms, with simpler organisms in lower layers and more complex ones in upper layers. This transition reflects the operation of natural selection, as organisms with advantageous traits are more likely to survive and leave behind more offspring, leading to the accumulation of beneficial traits over generations. By studying these fossils, scientists can draw conclusions about the process of evolution and the influence of natural selection.
The fossil record provides evidence for natural selection by showing the presence of transitional forms. These are fossilized organisms that exhibit characteristics of both older and more recent species, suggesting a gradual change over time. Additionally, the fossil record demonstrates the extinction of certain species and the appearance of new ones, indicating that some organisms were more successful in adapting to their environment than others. This pattern is consistent with the idea that natural selection acts on variations within a population, favoring those traits that increase an organism's fitness and survival.
