In his 1894 book, Materials for the Study of Variation, William Bateson coined the term Homoeosis with the following prose: The case of the modification of the antenna of an insect into a foot, of the eye of a Crustacean into an antenna, of a petal into a stamen, and the like, are examples of the same kind. It is desirable and indeed necessary that such Variations, which consist in the assumption by one member of a Meristic series, of the form or characters proper to other members of the series, should be recognized as constituting a distinct group of phenomena. ...I therefore propose...the term HOMOEOSIS...; for the essential phenomenon is not that there has merely been a change, but that something has been changed into the likeness of something else. The book was intended as a listing of the kinds of naturally occurring variation that could act as a substrate for the evolutionary process and Bateson took his examples from collections, both private and in museums, of materials displaying morphological oddities. Interestingly the person who also coined the term “Genetics” proffered little in the way of speculation on the possible genetic underpinnings of these oddities. It wasn’t until the early part of the next century that these changes in meristic series were shown to be heritable.

4e de couverture : "Jean Deutsch propose un nouvel ouvrage sur les merveilles de l’évolution biologique, dont il est l’un des spécialistes réputés. L’incroyable inventivité de la nature est illustrée par la variété des yeux dont sont dotés des animaux aussi différents que les méduses, les caméléons, la mouche, la coquille Saint-Jacques, le poulpe et bien d’autres. Darwin lui-même s’étonnait que le simple mécanisme de l’évolution ait pu conduire à des dispositifs de vision aussi différents et aussi complexes. Mais les connaissances biologiques les plus récentes éclairent l’apparition de tant de solutions au même problème : comment voir. Cette synthèse sur une question capitale de la théorie de l’évolution est sans équivalent et répond aux attentes des lecteurs intéressés par les subtils aspects conceptuels de cette théorie, comme à ceux que ravissent les curiosités du monde vivant. De nombreuses illustrations étayent le propos de l’auteur."

Qu’est-ce donc que le gène ? Dans quel contexte ce concept fondateur de la génétique est-il apparu, quelles interrogations a-t-il suscitées, quelles évolutions a-t-il subies au cours des décennies, et pourquoi est-il toujours en question aujourd’hui ? Malgré ses avatars, peut-on finalement se passer du concept de gène ? Jean Deutsch aborde ainsi certains des problèmes les plus actuels de la biologie et nous offre une synthèse des moments clés de la construction de la génétique moderne ainsi qu’une rencontre avec les personnages cruciaux, souvent remarquables, de son histoire. À partir du gène, il s’agit au fond de faire mieux connaître et comprendre cette science, et au-delà, la démarche scientifique elle-même, qui produit non pas des vérités définitives, mais des représentations provisoires, demandant toujours à être remises en cause.
