At
present, and based on what we know of the genetic regulation of development, these phenotypic changes in the gut are most likely the result of positive genetic changes in the genetic regulatory pathways controlling the development of the relevant
anatomical features, i.e. they are novel positive, heritable genetic
features producing a specific and functional novel
anatomical structure within the Genus.
The exhibition
features a number of works
presented at Tate for the first time since acquisition, such as William Orpen's meticulously detailed representations of the human figure,
Anatomical Studies (1906), used by students to study anatomy during the early part of the century.
