By studying embryos, scientists can compare the similarities and differences between the early stages of development of different species. This can help them understand the evolutionary relationships between organisms and how they have changed over time. For example, similarities in embryos of different species can suggest a common ancestor. Additionally, studying fossilized embryos can provide insight into the evolutionary history of a species and how it has changed over time. Overall, embryos can provide valuable information for scientists to understand evolution and the relationships between different organisms.
