three to five sentences, explain how the fossil record provides evidence for the idea of natural selection (4 points)
The fossil record provides evidence for the idea of natural selection by demonstrating the presence of transitional fossils. These fossils exhibit characteristics that are intermediate between different groups of organisms, indicating a gradual change over time. For example, the fossils of Archaeopteryx show features of both reptiles and birds, providing evidence for the evolution of birds from reptilian ancestors.
Additionally, the fossil record reveals the existence of extinct species that are different from any living organisms, further highlighting the process of natural selection. For instance, the fossil remains of extinct hominids such as Homo habilis and neanderthalensis provide evidence for the evolution of humans from common ancestors with other primates.
Furthermore, the fossil record helps establish the temporal sequence of species, showcasing the emergence and disappearance of different forms. This supports the concept of natural selection as species adapt to changing environmental conditions or face competition from other species.
Lastly, the fossil record demonstrates patterns of diversification, where groups of organisms rapidly evolve into multiple species in response to new ecological opportunities. This indicates the role of natural selection in driving speciation events and the adaptive radiation of diverse forms.
