Introduction

The query focuses on identifying the closest living relatives of dinosaurs. This topic is significant for understanding evolutionary relationships and the transition from ancient reptiles to modern species.

Key Insights

Birds as Closest Relatives of Dinosaurs:
- Birds are considered the closest living relatives of theropod dinosaurs, specifically within the clade Maniraptora, which includes both birds and their closest non-avian relatives.

Conclusion

Birds are the closest living relatives of dinosaurs, particularly theropod dinosaurs within the clade Maniraptora. This relationship highlights the evolutionary transition from ancient reptiles to modern avian species.
