Jews, Judaism and Genetically Modified Crops
Credit: USDA
Genetically modified (“GM”) crops are plant products which have been genetically altered for certain traits. Such traits include resistance to viruses, bacteria, fungi, nematodes, insects, herbicides and drought, as well as aspects of product quality like improved yield, nutritional value and longer shelf life. (See here and here.)
The characterization is somewhat of a misnomer. Modification of biological organisms is not a new process. It has been occurring in nature for billions of years. Indeed, the natural selection of some traits over others is the driving force of biological evolution, the process by which a species over time secures a competitive advantage in its environment. Today, though, the label of GM foods is meant to identify those products that have been modified or engineered by human means.
And yet, the intervention of humans in an otherwise natural process is not new either. Humans have been actively engaged in plant breeding for up to ten thousand years. An Assyrian relief, dated to 870 BCE, illustrates pollination of date palms by man.
Similarly, the Torah tells of Jacob manipulating his flocks of goats and lambs so that he would increase his herd with the fittest among them. (See Gen. 30:31-31:13.)That the author ambiguously attributed Jacob’s success to both magical sticks and God’s miraculous power is irrelevant, for present purposes. What is important is that the story is testament to the reality that at least since the text was written some twenty-five centuries ago, humans have recognized the desirability of and have sought to guide the alteration of existing species in ways thought beneficial. This guided intervention has produced a host of useful and now common food products, but it is, or was, slow, unpredictable, unreliable, costly and inefficient. read more
Science and Judaism: The Strange Claim of Dr. Schroeder (Part II)
In a prior post (10/18/11), we started to look at Dr. Gerald Schroeder’s argument in The Science of God (“TSOG”)(rev. ed. 2009) that the six biblical days of creation and the billions of years of the evolution of the universe as measured by scientists actually occurred over the same time period. Our focus was on Schroeder’s interpretation of certain biblical passages that he believes show that time is treated differently before and after the creation of Adam. (See, e.g., TSOG, at 52, 54.)
Now we are going to address that part of Schroeder’s argument that rests of physics and mathematics. In the concluding post of this series, we will review the conclusion of Schroeder’s conflation argument. read more
Science and Judaism: The Strange Claim of Dr. Schroeder (Part I)
The literal accuracy of the biblical description of the origin of the cosmos and of life itself has been the subject of controversy and reinterpretation for millennia. Even before recent scientific discoveries made the story of a six-day creation simply untenable as fact, many Jewish scholars, among others, readily acknowledged that the opening chapters of the Bible do not reflect a true portrayal of historic creation. (See, Post 10/11/11.)
Today that view has achieved a sort of consensus. With respect to B’reishit (Genesis), the Reform movement’s latest commentary asserts that the Bible “has a great deal to tell about God’s relationship to the world and about human beings and their destiny,” but concedes that the opening chapters are “unscientific, antiquated myths” that may be approached “in the same manner as one approaches poetry.” (Plaut, The Torah, rev. ed. (2005), at 6.) Etz Hayim, the Torah commentary published by the Conservative movement (2001) holds similarly: “The opening chapters of Genesis are not a scientific account of the origins of the universe. The Torah is a book of morality, not cosmology.” (At 3, emphasis supplied.) The Chumash (The Stone Edition)(1993), published as part of the more traditional Art Scroll series, accepts Rashi’s understanding that Torah starts with Creation in order to establish God’s supremacy, but acknowledges that “the Torah is not a history book . . . .” [All year citations are CE, unless otherwise noted.] read more
