Transitional fossils are fossilized remains of organisms that show intermediate characteristics between two distinct groups of organisms. They provide a crucial piece of evidence for evolution because they demonstrate gradual change over time, confirming the idea that species have evolved from common ancestors.
Transitional fossils fill in the gaps in the fossil record, showing the gradual development of species over millions of years. They provide a clear visual representation of the theory of evolution, demonstrating how a species can change and adapt over time to eventually become a new species.
By studying transitional fossils, scientists can track the evolutionary history of organisms and identify patterns of change and adaptation. This helps to build a more complete picture of the process of evolution and provides solid evidence to support the theory.
Overall, transitional fossils help to bridge the gap between different species and demonstrate the interconnectedness of all living organisms, providing strong evidence for the theory of evolution.
