IN THE BEGINNING THERE WERE no women population on earth perhaps until 1000 million years. Airy human males begot male offsprings by biological fission. In some kind of mutation, the first Airy Woman known as Satrupa came into existence from the airy Swyambhu Manu. It was during 700 - 400 million years when male gave up and women took the exclusive responsibility of procreation by laying eggs ( in their hydromorphic and amphibian bodies).

It was only after 99.3 m yrs. when women started menstruating and started delivering gross bodied 1 human beings regularly. ( Details 'The Real History of the Ancient World ISBN 9788190950268
