A few days ago I published a very short version of my approach regarding the biological characteristics of lice as related to the Talmudic statement in Masechet Shabbat 107b (http://www.toriah.com/pdf/Betech-MesechtaShabbos-On-Lice.pdf).
In your blogspot you said that the four refutations you wrote on your website refute my approach.
I will copy your four claims verbatim (emphasis mine) and I will try B”H to analyze them by interspersing my comments:
NS: Some have attempted to defend the notion of the scientific infallibility of the Talmud, or at least the applicability of this ruling, by reinterpreting this statement about lice. A popular argument is that the Sages actually meant only that the eggs of lice are halachically insignificant due to their small size, not that they do not exist.
1.1. IB 20/Jan/13:
I did not claim that.
NS: Similarly, some claim that the life-force of a louse is not halachically classified as an animal life-force (just as a plant is alive and yet is not classified in a halachah as a living creature). An alternate claim that is advanced is that since the eggs or larvae require this particular environment in which to develop, it can be said that they are generated from there.
1.2. IB 20/Jan/13:
Although these are not my claims, some could think that my approach can be categorized together with the two above. Thus, I will try to analyze the continuation of your “refutations” as they could theoretically apply to my approach. Please continue reading.
NS: However, there are numerous problems with such explanations, notwithstanding their obvious appeal.
1.3. IB 20/Jan/13:
I agree that “appeal” is not enough.
NS: First, there is no independent evidence for these explanations; they are presented simply on the grounds that there could not be a scientific error in the Talmud.
1.4. IB 20/Jan/13:
Although absence of “independent evidence” is not an evidence that Chaza”l did not mean that particular suggested explanation on their statements about lice, nevertheless I want to present the following that could be an independent evidence.
I have found three   Rishonim that clearly spoke about the “nits” (the eggs of lice), so they understood that there are lice and additionally there are egg-lice (besides the “betze kinim” a type of organism which is called eggs of lice).
NS: Yet, as we discussed in the introduction to this work, most authorities understand that the Sages of the Talmud did make a scientific error in believing that the sun passes behind the sky at night.
1.5. IB 20/Jan/13:
Undoubtedly this is an important issue I have also written about; but by now, it is beyond the scope of this short analysis on the reproduction of lice.
NS: And since the Sages spoke of a mouse that grows from dirt, they clearly did believe in spontaneous generation.
1.6. IB 20/Jan/13:
I do not agree that it is so “clear” in the case of the mouse that you have mentioned.
I will write B”H my view on this specific case you mentioned. But it should be clear that a detailed discussion of the mouse, is beyond the scope of this short analysis on the reproduction of lice.
In the case of this Talmudical “half-mouse” we are not discussing inanimate matter transforming into animate matter, but soil that is already an integral part of a preexisting living entity, which transforms (by an unidentified process) to organic material.
In this soil, maybe there were already organic residua, or certain organic material migrated from the flesh-part to the soil-part, and then became flesh.
Today we know from the cloning of Dolly, that from a single cell, we may obtain a complete organism, not only from a zygote, but even, a differentiated cell may recover its totipotentiality.
Therefore the case of the half-mouse is not a “clear” case of spontaneous generation (ד"ע).
NS: Thus there is no reason to accept that they could not have believed that lice generate this way, which was the common belief in their era.
1.7. IB 20/Jan/13:
We have found some cases where Chazal “scientific” statements were independent from which was the common belief in their era.
NS: Second, the words of the Talmud say nothing about the eggs being halachically insignificant, or about the life-force of lice not being like that of other animals. It simply states that they do not reproduce sexually.
2.1. IB 20/Jan/13:
I could not find the latter in Chazal writings.
NS: While it is not impossible that this could be a shorthand reference for something else, the burden of proof is certainly upon those who would make such a claim. Especially since, in Talmudic times, the entire world believed that lice spontaneously generate, it is highly unreasonable to state that when the Sages spoke of lice as not reproducing sexually, they intended a different meaning entirely.
2.2. IB 20/Jan/13:
See above 1.7 and 2.1
Third, such explanations are inconsistent with the views of the traditional Talmudic commentators. Rambam, Rashba, Ran, Tosafos and others all state that lice spontaneously generate from sweat or dust. True, it is not impossible that they misunderstood the nature of the Talmud’s ruling—indeed, we posited similarly in the case of mermaids. Yet in the case of mermaids, there was compelling textual evidence that the Talmud was referring to dolphins instead; here, no such evidence exists. Furthermore, those who posit that the Talmudic statement about lice must be scientifically correct are usually the same people who are reluctant to posit that the traditional commentators all erred in their understanding of the Talmud.
3.1. IB 20/Jan/13:
The apparent inconsistency between my approach and the Rishonim’s commentaries is addressed in the Hebrew expanded version of my article on lice.
Please see the linked document.
NS: The final objection to such reinterpretations of the Talmud’s statement is that there is a straightforward refutation from the continuation of the Talmud:
Abaye said: And do lice not reproduce? Surely it was said, “God sits and sustains from the horns of aurochsen to the eggs of lice” (which shows that lice come from eggs)? — That refers to a type [of organism] which is called eggs of lice (but not that lice actually hatch from these).
If the Sages were not denying the existence of lice eggs, why do they reject the simple meaning of the statement that speaks about God sustaining the eggs of lice, and resort to difficult explanations instead? Let them simply state that although lice do hatch from eggs, these are too small to be halachically significant! It therefore seems that they did not consider this possibility. (I am aware that some claim that the Talmud means that since the eggs are halachically insignificant, they cannot be the subject of the statement about lice eggs. However such a reading is highly contrived, lacks any evidence, and is certainly not how the Rishonim and Acharonim understood the Talmud.)

The apparent inconsistency between my approach and the Gemara-text is addressed in the Hebrew expanded version of my article on lice.

P.S. IB 20/Jan/13:
I am ready B”H to analyze comments directly related to our issue:
