What were the observations of the three scholars about Gulliver?

From the text:

They all agreed that I could not be produced according to the regular laws of nature, because I was not framed with a capacity of preserving my life, either by swiftness, or climbing of trees, or digging holes in the earth. They observed by my teeth, which they viewed with great exactness, that I was a carnivorous animal; yet most quadrupeds being an overmatch for me, and field mice, with some others, too nimble, they could not imagine how I should be able to support myself, unless I fed upon snails and other insects, which they offered, by many learned arguments, to evince that I could not possibly do. One of these virtuosi seemed to think that I might be an embryo, or abortive birth. But this opinion was rejected by the other two, who observed my limbs to be perfect and finished; and that I had lived several years, as it was manifest from my beard, the stumps whereof they plainly discovered through a magnifying glass. They would not allow me to be a dwarf, because my littleness was beyond all degrees of comparison; for the queen’s favourite dwarf, the smallest ever known in that kingdom, was near thirty feet high. After much debate, they concluded unanimously, that I was only relplum scalcath, which is interpreted literally lusus naturæ; a determination exactly agreeable to the modern philosophy of Europe, whose professors, disdaining the old evasion of occult causes, whereby the followers of Aristotle endeavoured in vain to disguise their ignorance, have invented this wonderful solution of all difficulties, to the unspeakable advancement of human knowledge.
