Final answer:
The evolutionary novelties distinguishing theropods from other dinosaurs include a broad exposure of the lachrymal bone, a clawed hand, and a bowed femur. These features support the idea of theropods as the ancestors of modern birds, exemplified by the Archaeopteryx fossil.
Step-by-step explanation:
Evolutionary novelties that distinguish theropods from other dinosaurs include D. all of the above: broad exposure of the lachrymal bone, a clawed hand, and a bowed femur. Theropods are a group of bipedal predators from which modern birds are believed to have evolved.
This subgroup of the Saurischia ("lizard-hipped") dinosaurs is characterized by these unique features which are part of the evolutionary adaptations leading to the emergence of birds. The discovery of the Archaeopteryx fossil supports this evolutionary link, showcasing traits of both dinosaurs and birds, highlighting the transitional nature of this species.
