The above video clip is from the debate โThe Qurโan and the Bible in the Light of Scienceโ between Dr. William Campbell (USA) and Dr. Zakir Naik (India) in April 2000. In this section of the debate Dr. Campbell attempts to refute verses relating to human development (embryology) as described in the Qurโan.
In the above video clip Dr. Campbell discusses the termย โalaqahย ุนููุฉย (the second stage of development as mentioned in the Qurโan). The termย โalaqahย has several meanings, one of which is a โleechโ. It has been suggested that the early embryo resembles a leech in appearance and that such a description was scientifically unknown in earlier times.
Dr. Campbell in response says:
He [Dr. Keith L. Moore] says another verse in the Qurโan refers to theย leech-like appearance, and theย chewed-like stages of human development. From this definition,ย Dr. Moore has gone ahead to propose that a 23 day embryo, 3 millimeters long โ that is an eighth of an inch โ I can hardly put my fingers that close together without touching. This is Carnegie stage 10 shown on the inside cover of Mooreโs book [figure 1]:
Figure 1: Carnegie Stages 7-17.
This is the beginning, and here is the sperm entering the egg โ so thatโs Stage 1. [It] comes down here to Stage 6 in the second week.
And here is the 3rd week. And there is Stage 10, and here is day 23 [figure 1], and this is what Dr. Moore wants to say โlooks like a leechโ.
If we could look further though, and look at the X-Ray [Figure 2]:
Figure 2: Carnegie Stage 10.
Here is day 22 and the back bone is still open. And when we look at day 23 the back bone is open there, and it is open there, and the head is wide open, it doesnโt look like a leech at all!
And if you keep onโฆ this is the diagram of it [Figure 3]. The head is open, the rostral neuropore.
Figure 3: Human embryo at day 23-24.
And finally this diagram [Figure 4] shows there is the 20 day embryo. Itโs got a yolk sac, itโs got an umbilicus, it doesnโt look like a leech at all.

RESPONSE (1): The outer shape of the embryo resembles a leech
If we begin by examining the outer shape of the embryo, we clearly see that the shape of the embryo does in fact resemble a leech. Figure 5A shows a lateral view of an embryo at days 24 to 25. Figure 5B shows a medicinal leech (taken from the BBC TV documentary The Human Body, 1998).
Note the remarkable similarity in appearance between the embryo and leech. The embryo during this time is no more than 2.5-3.0 mm is size. It is only when one views the embryo under a microscope that you see the details that make it look like a leech.
Figure 5: A, shows a lateral view of an embryo (size 2.5-3.0 mm) at days 24 to 25. (Modified from Moore & Persaud: The Developing Human 8th Edition) B, Hirudo medicinalis, medicinal leech (modified from The Human Body. The Incredible Journey from Birth to Death, ยฉ BBC Worldwide Ltd, 1998) C, Scanning electron micrograph of an embryo at Week 4, 26 โ 30 days. (Professor Kathy Sulik, The University of North Carolina). Note the leech-like appearance of the human embryos at this stage.
RESPONSE (2): Viewing the internal organs of the human embryo and leech
Dr. Campbell presented a number images of the human embryo at 22-23 days where the internal organs could be observed through the skin as we see in Figure 2. A leech appears to have none of the characteristics displayed in Figure 2.
If we were to dissect the leech by removing its outer skin, what would its internal anatomy actually look like?
Figure 6 A-C shows views of human embryos during the third and fourth weeks of development (between 22-26 days). The internal organs are clearly visible. Now look carefully at Figure 6D which shows two illustrations depicting the internal structures of a leech.
Once again, note the remarkable similarity in appearance between the embryos and the anatomy of the leech. Note also how the leechโs body is made up of a number of similar segments which resemble the somites in the human embryos. Click on Figure 6 to view a higher quality image.
It is truly remarkable that if we dissect both the embryo and leech (by removing their outer skin) and observe their internal organs, we find that the appearance of their internal structures are similar.
How is it possible for the external shape of the embryo AND its internal anatomy to resemble a leech?

RESPONSE (3): The head of the human embryo at days 22-24 resembles the sucker of a leech
Dr. Campbell also showed illustrations of the embryo at 23-24 days (Figure 3) with its head wide open. In Figure 7 below we see a scanning electron micrograph of the embryo with its head still open, and a scanning electron micrograph of the rear sucker of a leech. Look at the head of the embryo and the leechโs rear suckers and note once again, the remarkable similarity in appearance between the embryo and leech.

RESPONSE (4): Dr. William Campbell confusing the terms embryo and conceptus
Dr. Campbell stated:
And finally this diagram [Figure 4] shows there is the 20 day embryo. Itโs got a yolk sac, itโs got an umbilicus, it doesnโt look like a leech at all.
Dr. Campbell seems to be confusing the termsย embryoย (the developing human during its early stages of development) andย conceptus.ย The conceptus includes the embryoย as well as the embryonic part of the placenta and its associated membranes: amnion, chorionic (gestational) sac, and umbilical vesicle or yolk sac.ย It is the embryo that resembles a leech not the conceptus.ย For a discussion of the embryo at this stage of development see the paperย Embryology in the Qurโan: The โAlaqah Stage.
SUMMARY
- The outward shape of the embryo at 22-25 days resembles that of a leech
- The internal structure of the leech resembles a human embryo of 22-26 days
- The head of the embryo appears to resemble the leechโs rear sucker.
The Qurโanic term alaqah refers to the embryo when it is extremely small. Due to the small sizes involved scientists could not have recognised the detailed features of the โalaqah stage as Dr. Moore states:
Dr. Keith L. Moore
It is remarkable how much the embryo of 23-24 days resembles a leech. As there were no microscopes or lenses available in the 7th century, doctors would not have known that the human embryo had this leech-like appearance. In the early part of the fourth week, the embryo is just visible to the unaided eye because it is smaller than a kernel of wheat.
