Viviparous Quotes (2 quotes)

There are some viviparous flies, which bring forth 2,000 young. These in a little time would fill the air, and like clouds intercept the rays of the sun, unless they were devoured by birds, spiders, and many other animals.
Oeconomia Naturae, The Oeconomy of Nature. Trans Benjamin Stillingfleet, Miscellaneous Tracts Relating to Natural History (1775), revised edition, 1777, 119.

We, however, maintain … that all animals whatsoever, even the viviparous, and man himself not excepted, are produced from ova; that the first conception, from which the foetus proceeds in all, is an ovum of one description or another, as well as the seeds of all kinds of plants.
As translated by Robert Willis in The Works of William Harvey (1847), Vol. 7, 170. Harvey’s doctrine, given herein, has been summarized in later literature as: omne vivum ex ovo omnia, (all life from an egg). Also see the quote “Ex ova omnia,” elsewhere on this webpage.

Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
