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.

Advances in Experimental Medicine and Biology. Studies from the 20th to the 21st Century. Devoted to the evolution of Hox genes and Hox complexes, in relation to animal evolution. Discusses function of the Hox genes at the organism level. Examines biological function of the Hox genes in the Bilateria. 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.

Just as the 19th century can be considered the age of cellular biology, the 20th and 21st centuries were characterized primarily by developments in molecular biology

Just as the 19th century can be considered the age of cellular biology, the 20th and 21st centuries were characterized primarily by developments in molecular biology. Important conceptual and technological developments. Lifesaving advances in medicine, for example, had allowed people to live longer and resulted in a dramatic drop in death rates (primarily in developed countries), contributing to an explosive increase in the human population. Chemical contaminants introduced into the environment by manufacturing processes, pesticides, automobile emissions, and other means seriously endangered all forms of life.
