And of every thing We have created pairs:
That ye may receive instruction.
-- Sura 51:49
And in his commentary on this verse Yusuf Ali writes:
To make a claim about everything is always bold and indeed only God will ever be able to make claims about everything since such claims need omniscience.
But on the other hand, they are also very dangerous since one counterexample proves such a bold claim wrong.
In electricity there is positive and negative charge creating electrical force fields, this is true. But where is the counterpart for the force of gravitation? It always is attracting. There is no repelling gravity.
But maybe Yusuf Ali was just a bit too enthusiastic with his interpretation of everything? Mayby the Qur'an meant only things that are somehow "alive" like plants and animals? The Qur'an does say "everything" but let us look then to the restricted part of living beings.
I took the freedom to ask around on the biology newsgroups to find out more about this claim. Here a list of some responses I got.
There are quite a few examples of organisms which are exclusively parthenogenetic. I might refer you to Graham Bell's "The Masterpiece of Nature", a weighty tome which has all you could care to know about the evolution of sexual reproduction. Even though there are quite a few example of parthenogens, they tend to be taxanomically isolated, suggesting that they are all of recent origin (often due to hybridization between two disparate specied) and are short-lived in evolutionary time. There is one notable exception, however, which is the topic of study in my lab. Bdelloid rotifers are an entire class of animals which, as far as anyone can tell, has been reproducing entirely without any form of genetic exchange for quite some time (perhaps more than 50 million years), with over 350 species identified. If you're interested in more info about bdelloids and our work, I'd refer to our lab web page, which includes a copy of our research proposal which gives a fair amount of background material.

Actually, one of the students here told me that there is such a thing as a purely asexual reproducing organism. Here is the reference: Science 203: 1247-1249. 1979. It is a lizard called Cnemidophoras. Personnally I don't believe it to be possible, but this "accident" may have arrived quite late in the evolution. Unless this organism "reverts" to sexuality, it is in my view in an evolutive pitfall, if it is an asexual reproducer.
The list is actually decently long : bacteria, fungi imperfecti, etc. All members of the Monera Kingdom reproduce asexually only. Yes, the Plantae and Protista Kingdoms do produce both ways, but almost never only asexually. As for the fungi, a certain group, the fungi imperfecti, are classified as such because no forms of sexual reproduction have been observed. Concerning your question about "higher" species, no members of the Kingdom Animalia produce only asexually (the scientific term is not non-sexual). There are some rare cases of lysogeny (sp?), but it is very rare. Hope this helps.
There is a whole group of fungi (Deuteromycete/Fungi Imperfecti) which do not have sexual cycles. All are related to sexual species but do not reproduce sexually. Many have rather complex mechanisms (parasexual cycles) to allow genetic recombination but they are not based on meiosis and gametic fusion as in true sex. Your best place to start to find out about them is in a good introductory text such as the 4th ed of Alexopoulus, Mimms and Blackwell (Wiley, 1996). This will point yopu to the specific organisms that fulfil the criteria you are looking for.
There is a whole group of organisms wich do no practise sex: fungi imperfecti. This is a group of mushrooms, which don't produce gamets and therefore cannot be put in an certain taxon. An other curious member is the european population of Elodea. All plants here are of the same sex and can therefore only use vegetative amplification.
Could it be that God is wrong? And wrong in so many cases? Or could it be that the one who was wrong here was not God? Maybe Muhammad was a good observer of the world around him, but he was not omniscient. And it shows in the above and other contradictions collected here.
