A diagram titled Classification of Animals shows a tree of images and names of animal ancestry. A diagram, labeled Classification of Animals, shows images of animals under different groups. From left to right, top to bottom: ● Classification of Animals to Vertebrates ○ Vertebrates to Warm-Blooded ■ Warm-Blooded to Mammals ● Mammals to bear, tiger, whale ■ Warm-Blooded to Birds ● Birds to ostrich, peacock, eagle ○ Vertebrates to Cold-Blooded ■ Cold-Blooded to Fish ● Fish to salmon, goldfish, guppy ■ Cold-Blooded to Reptiles ● Reptiles to turtle, crocodile, snake ■ Cold-Blooded to Amphibians ● Amphibians to frog, toad, newt ● Classification of Animals to Invertebrates ○ Invertebrates to With Jointed Legs ■ With Jointed Legs to with 3 pairs of legs ● With 3 pairs of legs to ant, cockroach, lady ■ With Jointed Legs to with more than 3 pairs of legs ● With more than 3 pairs of legs to scorpion, spiders, millipede ○ Invertebrates to Without Legs ■ Without Legs to Worm-like ● Worm-like to earthworm, leech ■ Without Legs to Not-worm like ● Not-worm like to fluke worm, tapeworm.

Based on the classification diagram provided, the two groups of organisms that share the most similar DNA would be turtles and frogs.
Both turtles and frogs are classified as cold-blooded vertebrates, and they share a more recent common ancestor compared to the other pairs of organisms listed. The other comparisons (warm-blooded and cold-blooded, bears and salmon, vertebrates and invertebrates) involve larger and more diverse groups that are less closely related genetically.
