Virgin Births? Nothing New!
January 13th 2008 17:29
Virgin births among animals probably existed almost from the beginning. Especially among the more primitive ones. Parthenogenesis is when an egg starts to divide without being fertilized. Here is an article about a shark that performed such a 'miracle'!
From the article:
Parthenogenesis...occurs in a number of lower animals such as bees and ants but, it was thought, not in higher animals including cartilaginous fish such as a shark.
That is totally false, because I've known about it for years in higher animals such as lizards! I also learned that in lizards the offspring are all females. It is a survival skill when no males are present. Lab experiments that result in pathenogenesis births don't count.
Other articles can be found here, here, here, and here to name a few.
