The Union government’s position vis-a-vis the United Nations conference on racial and related discrimination world-wide seems to be the following: discuss race please, not caste; caste is our very own and not at all as bad as you think. The gross hypocrisy of that position has been lucidly underscored by Kancha Ilaiah. Explicitly, the world community is to be cheated out of considering the matter on the technicality that caste is not, as a concept, tantamount to a racial category. Internally, however, allowing the issue to be put on agenda at the said conference would, we are particularly admonished, damage the country’s image. Somehow, India’s spiritual beliefs elbow out concrete actualities. Inverted representations, as we know, have often been deployed in human histories as balm for the forsaken—religion being most persistent of such inversions. Yet, we would humbly submit that if globalising our markets are thought good for the ‘national’ pocket, globalising our social inequities might not be so bad for the mass of our people. After all, racism was as uniquely institutionalised in South Africa as caste discrimination has been within our society; why then can’t we permit the world community to express itself on the latter with a fraction of the zeal with which, through the years, we pronounced on the former? As to the technicality about whether or not caste is admissible into an agenda about race (that the conference is also about ‘related discriminations’ tends to be forgotten), a reputed sociologist has recently argued that where race is a ‘biological’ category caste is a ‘social’ one. Having earlier fiercely opposed implementation of the Mandal Commission Report, the said sociologist is at least to be complemented now for admitting, however tangentially, that caste discrimination is a reality, although in his view, incompatible with racial discrimination. One would like quickly to offer the hypothesis that biology, in important ways that affect the lives of many millions, is in itself perhaps a social construction. But let us look at the matter in another way.

If it is agreed—as per the position today at which anthropological and allied scientific determinations rest—that the entire race of homo-sapiens derived from an originally black African female (called ‘Eve’) then one is hard put to understand how, on some subsequent ground, ontological distinctions are to be drawn either between races or castes. Let us also underline the distinction between the supposition that we are all God’s children and the rather more substantiated argument about our descent from “Eve”, lest both positions are thought to be equally diversionary. It then stands to reason that all subsequent distinctions are, in modern parlance, ‘constructed’ ones, and, like all ideological constructions, attributable to changing equations between knowledge and power among human communities through contested histories here, there, and elsewhere. This line of thought receives, thankfully, extremely consequential buttress from the findings of the Human Genome Project. Contrary to earlier (chiefly 19th Century colonial) persuasions on the subject of race, as well as, one might add, the somewhat infamous Jensen offering in the 20th century from America, those findings deny genetic difference between ‘races’. If anything, they suggest that environmental factors impinge on gene-function, as a dialectic seems to unfold between nature and culture. It would thus seem that ‘biology’ as the constitution of pigmentation enters the picture first only as a part of that dialectic. Taken together, the originally mother stipulation and the Genome findings ought indeed to furnish ground for human equality across the board, as well as yield policy initiatives towards equitable material dispensations aimed at building a global order where, in Hegel’s stirring formulation, only the rational constitutes the right. Such, sadly, is not the case as everyday fresh arbitrary grounds for discrimination are constructed in the interests of sectional dominance.

It was one of their medical observations: that human bone is one of the few tissues that can re-grow after injury. Hippocrates knew that and hoped that power could be harnessed for healing. Now, 2400 years later, reports from commercial and university laboratories suggest that scientists have begun to do just that: to grow bones and cartilage virtually at will. “This is exciting because we are mimicking the natural process of development,” said Dr. A. HariReddi, a professor of biology and orthopedics at the John Hopkins medical center in Baltimore, who has worked on bone growth for more than thirty years. “We are following the same steps that occur in the first week after conception.” The success is one of several in the new field of tissue engineering, the growing of spare parts for the body. The new power to grow human tissues and organs is a result of years of basic research followed by rapid progress in molecular biology and genetic engineering. Among the tissues now grown successfully, at least in the laboratory, are skins, bone cartilage, liver, kidney and teeth. The new work on bones is among the most advanced, and researchers say that the new treatment will soon be available for a variety of conditions in which the body needs to grow new bones but cannot. The key to the recent success is the family of molecules known as BMPs, for bone morphogenic proteins. They are made when an injury occurs and set off the formation of new bone and cartilage by homing in on certain immature or unspecialized cells, and inducing them to proliferate and become one of several specialized tissues, like bone and cartilage. All this was learned over the last few decades, as scientists labored to find the magical molecules that would produce natural bone growth. They pulverized bones and removed the calcium from the resulting powder, working with the remaining material to isolate the factor that was causing bone growth.

“But the work for many years went like a snail,” Reddi said. Then in recent years, with the new techniques of molecular biology, scientists were able to isolate both the proteins responsible for bone growth and the genes responsible for producing them. Roughly, 20 protein molecules have been identified that could induce bone growth. Each of the molecules also seems to have the power to stimulate other to begin growing. Reddi says that he and other scientists had found that the genes that made the BMPs were both ancient and general. Even fruit flies, which have no bones, use them to set off growth of specialized tissues like wings. “These are not just bone signals but are general signals to initiate differentiation in many tissues,” he said, referring to a wide variety of tissues ranging from kidneys to brain to gonads. “What we are working with, is the body’s own signaling molecules that cells tell to go ahead, ‘you be bone’ or ‘you be muscle’,” said Dr. Charles Cohen, chief scientist at Creative Biomolecules, one of the companies working on making products from bone proteins. “There are two steps,” he said. “The BMP signal to the cells says, ‘Go!’” he said. “Then information the cells get from the neighborhood where they live tells them to be bone or cartilage. “Over the last five or six years, dozens of papers have shown that researchers can reliably stimulate natural bone growth in mice, rabbits, dogs and monkeys. Now the first tests from human experiments are coming in, and they show success as well, researchers say. Two small studies in humans were presented at scientific meetings last month by representatives of the Genetic Institute Inc., in Cambridge, Massachusetts. One was a study at four universities in which twelve dental patients with bone loss in their upper jaws underwent oral surgery in which BMP-2 and a sponge made of artificially produced collagen, a central component of skin and bone, were implanted in the area where was none, and all went on to get implants. The standard treatment for all these cases would have involved surgery of the mouth and also surgery of the harvest bone from the hip for implantation in the mouth. Such procedures are frequently successful, but they are expensive and lengthy and simply cutting down on surgery reduces risk. “We are talking about an outpatient procedure versus the current treatment which involves hospital stay and surgery,” said Dr. Gerald Riedel, at the bone protein project.
