Homology
Explanation:
Homology refers to the presence of similar or shared body structures, body parts, gene sequences, proteins, etc. among various lineages. It represents divergent evolution of these lineages from a common ancestor.
Presence of various similar structures in human and salamander reflects the fact that these two species have shared a common ancestor during their evolution. The shared ancestry between human and salamander led to the presence of various homologous body parts and identical gene sequences in them.
The statement that is true about this species is A. Deinonychus have claws that were likely adaptations for disabling their prey. One theory by Fowler states that D<span>einonychus may capture their prey by "raptor prey restraint" model wherein the dinosaur leap to its prey, pinning it to the ground and gripping it tightly with the use of its claws thus disabling the prey.</span>
