The modern concept of reproductive biology was known to the ancient sage Agasthiayar, a Tamil scholar lived in 800 BC. Based on his classical palm script, a book Panchakaaviya nigandu was prepared and it documented many scientific facts which were fully understood scientifically in late 19thcentury. If so how the science behind the biological functioning fully understood recently was known to ancient Tamil Sages is really a mystery. The ancient script reproduced from palm scripts narrates the size, shape, the movement of spermatozoa towards egg in the uterus and transfer of 96 elements in the gametes representing the paired chromosomes is also very interesting. The present scientific study of the ancient Tamil literary work brings out the science that may be forming a foundation for present day research,
