Ok. I know that you are all as fascinated by this subject matter as I am, not. Still it's a really interesting subject. The correct term for it is parthenogenesis. This means a female egg will self fertilize without the presence of a male and she will give birth.

This has been know to happening with insects, amphibians and reptiles. Usually this happens after long periods without the presence of any males. Recently just to show you how far behind our science is, they realised that sharks have this ability, maybe not all sharks, but at least two species, including the hammerhead shark.

A female shark that had been in an aquarium died, and upon autopsy it showed that she was carrying a fully formed pup. Neat.

Could this happen in other species? Probably, but since science has not been looking for virgin births, when they see it, they probably attribute it to other things, such as long term sperm storage, yeah. If you are not looking for proof of a phenomenon, how can you prove it's existence?

So if this happens with sharks, reptiles, and other amphibians could it ever happen with mammals? With this is an interesting question, and I don't know if they are looking into this, because their science tells them that it's not likely, that is of course until it happens. If you are not looking for a phenomenon, then you won't recognise it even if it does happen.

The problem with mammals is of course by their very nature, they often take care of their young, and many live in communal groups, whales, bats, humans, etc, so the circumstances that would bring about parthenogenesis in other species probably does not present itself as readily in mammals.

I think it's interesting and something that science should try to look into. Since we know that when this happens the offspring has fused chromosomes of the mother, then we could genetically test mammals to see if this phenomenon had happened in any species that exist alone for long periods of time. Here is the story about the shark and it gives you a lot to think about.



Since we now know that this does happen in nature, what we don't know are what are the mechanism that trigger this effect? Is it a rear occurrence or something programed in all genetics to keep the species going? There are a lot of unanswered questions, because if you know what triggers the process, then you can say if it could happen in other species.



This article is saying that parthenogenesis would not be possible with humans, but I don't believe that for a second. Until we understand more about the process, what triggers it, and how do we know what the cells would be capable of? All humans start off as female embryos, and then with the male hormone they become male vs female. How do we know what processes would kick in under these circumstances in nature? Currently however science has not reported parthenogenesis in any mammals, but till a couple of years ago, they had not reported anything in sharks either, and thought that it was impossible, till it happened.

If we can do this in the lab, why could this not naturally occur in nature, when we see that there is a natural process in nature that does make this possible for other species? Could it be that we are not looking?

What we need to do to set science on it's ears once more is to find the process working in nature, which I do believe is fully possible. Again however, we need to know more about what starts the process, so that we can look for optimum circumstances where that can be achieved? Is it just removing males from the environment for long periods of time? Does the female need to be isolated also? Are all creature capable of this, or just some special ones within the species? What tells the process internally to start?

Till science can answer these questions conclusively, I don't think it's fair for them to presume what is and what is not possible at this stage, because we don't know enough about what starts the process, we just know that it is capable of happening.
