From Genes for Intelligence to Our Understanding of Genes

Published online by Cambridge University Press:  28 February 2024

Extract

From its very beginnings, this century has been under the sign of genetics. Indeed, it was in 1900 that the laws established by Mendel in the mid-nirieteenth century were rediscovered. In that same year, Landsteiner identified the first human blood typing, the ABO system. At that time, agronomists, eugenicists, and physicians were the principal agents of the development of genetics. The chromosome theory of heredity was asserted beginning in 1911; it was followed in the 1940s by the understanding of the role of the gene in cellular metabolism, and in 1954 by the explanation of the structure of the DNA double helix. The pre-eminence of genetics was to increase through the second half of the century, particularly in the 1970s with the advent of genetic engineering.

Notes

1. Reference is made here to the growing importance accorded to biological kin ship and to the desire to preserve one's genes for posterity through one's descendants, whereas kinship was first defined by affective bonds within an ethno-sociological context, without particular reference to biology.

3. The lack of interest on the part of certain biologists and the ignorance of many technocrats with respect to these questions often stem from an unshakable faith in the inevitability of "progress." "One of the inevitabilities of scientific progress is that if something can be done then it will be done," according to Daniels et al., in Journal of Biosocial Sciences 28 (1996): 491-507. Moreover, some ways of accentuating and encouraging the hope that may arise out of any sci entific advance is in fact only a clever tactic for leaving one's hands free to cover up research whose consequences will ultimately escape control (on this subject, see the analysis by Axel Kahn, Futuribles 223 (1997): 5-27.
