Explanation
Why Correct: The horse was not depicted on Harappan seals. The Harappan people were not familiar with the horse; its bones are absent from Harappan sites, and the animal appears only in post-Harappan (Vedic) contexts. Common animals on Harappan seals include the humped bull (zebu), elephant, rhinoceros, tiger, and various composite creatures.
Distractor Analysis: The humped bull (zebu) is one of the most frequently depicted animals on Harappan seals, especially on the famous Pashupati seal. The elephant appears on several seals, including the Pashupati seal. Sheep are also depicted on some Harappan seals, though less commonly than the bull. The horse is the animal not depicted; its absence is a key archaeological marker distinguishing the Harappan civilization from the later Vedic period.
Takeaway: The horse (ashva) first appears in the Indian subcontinent in the late Harappan/post-Harappan period, around 2000-1500 BCE, and is prominently associated with the Vedic Aryans. The absence of horse bones and horse depictions is a major piece of evidence used to date the decline of the Indus Valley Civilization.
