Final answer:

The circulatory system similarities between frogs and humans are due to shared evolutionary history and genetic factors.


Explanation:

Amphibians have a relatively complex circulatory system with a three-chambered heart. This circulatory system is shared with most reptiles and is characterized by partial separation of oxygenated and deoxygenated blood to enhance efficiency.

Scientists discovered that many animals, including humans and frogs, share similar embryonic morphology due to the presence of genes dictating developmental direction that are common among various species.

The similarity in the circulatory system between frogs and humans is a result of their evolutionary history stemming from a common ancestor that shaped their anatomical similarities.
