From the Hindu religious epic, the Mahabharata, says one of the warriors learns a battle tactic hearing his father speaking, while he is still in the womb.
Keeping the religious aspect out of this, my question is whether such detailed learning is possible or proven?
Wikipedia summary of this episode in the Mahabharata
As an unborn child in his mother's womb, Abhimanyu learned the knowledge of entering the deadly and virtually impenetrable Chakravyuha (see Wars of Hindu Mythology) from Arjuna, his father. The epic explains that he overheard his Arjuna talking about this with his wife Subhadra from the womb. Arjuna explains to Subhadra in detail, the technique of attacking and escaping from various vyuhas (an array of army formation) such as Makaravyuha, Kurmavyuha, Sarpavyuha etc. After explaining all the vyuhas, he explains about the technique of cracking Chakravyuha. Arjuna explains to her how to enter the Chakryavyuha. When he was about to explain how to exit from the Chakravyuha, he realises that Subhadra is asleep and stops expounding on the Chakravyuha further. As a result, the baby Abhimanyu in the womb did not get a chance to learn how to come out of it.
