The Chasam Sofer (Toras Moshe parshas Shemini) writes that the meaning of the Medrash (cited by many Rishonim) that the pig is called a חזיר because עתיד הקב"ה להחזירה לישראל - Hashem is going to "return" it to the Jewish people - is that the physiology of the pig will be altered to chew its cud (the Kosher sign that it currently does not have) and will ...


I'd asked Rabbi Hershel Welcher of Queens a similar question, about goats that were given a bit of spider genes so they would produce gossamer in their milk.

Fish were not harmed: the Gemara notes that marine life was not harmed by the Mabul. (Sanhedrin 108a, quoted by Rashi on Bereshis 7:22) that were on the dry land: But not the fish, which were in the sea. — [Sanh. 108a] Maharsha says that only the water that covered the land was boiling hot. Others say that a cone of water under the ark was ...
