Remeasurements of the children for symmetry and for growth are planned for a later date as well. We also plan complete medical and dental evaluations of our children. The first article based on the research has appeared in the journal Evolution and Human Behavior. This specialization is particularly well-developed in women and we believe that asymmetry of the ears partly reflects a breakdown of the usual pattern. The Jamaican children are more symmetrical than a comparable sample of English children, boys are ever so slightly more symmetrical than girls, primarily due to their symmetrical elbows.
Size increases absolute asymmetry, while age is associated with greater symmetry.
Each child is identified by a number and all the scientific information is stored by reference to a child s number. Each child is paid to a modest sum to participate in the project. In addition to teachers and principals, Jamaican students are also employed to help with the project. We gratefully acknowledge the permission of the Ministry of Education and Culture and the cooperation of the three schools in St Elizabeth, especially the Top Hill Primary School. Our aim is to follow these individuals if possible into adulthood.
