Sir:
Professor Andy McIntosh, in yesterday's letters, appoints himself arbiter what 'any serious thinker' knows. If he wishes to include himself among that august tribe, he should get his facts straight. While trilobites did indeed first appear in the fossil record at the base of the Cambrian, the first trilobites had simple, holochroal eyes. The complex, double-lensed schizochroal eyes which he claims 'have no precursor in the rocks' are in fact derived from these simpler eyes, and appeared much later, in the Ordovician. A convincing account of their evolution has been given by Levi -Setti (2002).
Yours Faithfully
