GENOMES AND CULTURAL HERITAGE DEMAND COMMON APPROACHES TO FUTURE CHALLENGES

The science of Biology, and particularly its subfield Genetics, determines that every human being carries two types of traits during his/her lifetime: inherited and acquired. The inherited properties come from the interaction of genes contained in the father’s sperm and the mother’s egg when they combined to create the individual. The acquired are formed mostly during the early years of life through the interaction of each individual with the natural and man-made environment in which he/she grows up.

However, the genes of our parents contain properties and characteristics of two categories. Some are in harmony with the apparent characteristics of the parents, while others result from non-apparent traits, which are the recessive genetic factors. From the joining of sperm and egg during the creation of new life, it is equally likely that characteristics from both these groups of genes will appear. This possibility points to the research of the genome of our distant relatives from whom our parents inherited their genetic material. (Note that a genome is all the genetic material of each organism, while a gene is the basic physical unit of heredity in living organisms, part of the chromosome that passes on information about properties from one generation to the next). The logical analysis imposed by this cause ultimately leads to common racial characteristics of the population groups that have long inhabited each geographic area. The research process to identify these characteristics is generally difficult, but it is facilitated if the reference geographical areas are “closed,” i.e., if they have limited communication with other areas over long periods of time. This category also includes Mani, which for about four centuries before the creation of the modern Greek state, and for several decades afterwards, had limited communication with other regions. The mapping of the human genome, completed in recent decades, allows for the comparison of the genome of contemporary individuals with the genome of population groups that are believed to have contributed to its formation in distant periods of time, when they settled in these specific areas. However, a prerequisite for the reliability of the results of this comparison is a sound knowledge of the relevant historical data of each era combined with archaeological research that has led to the recording of genetic material from the bodily remains of individuals from those periods.

Moreover, in the creation of acquired traits, a dominant role is played by each child’s interactions with the environment in which he/she is raised, both the immediate and the wider family environment, as well as the physical space in which he/she develops. The influence of the customs and traditions of the society in which he/she lives, the language he/she first hears spoken, and in later years, the approach to the supernatural element through the religion embraced by his/her family environment also play a dominant role. According to more recent approaches of Sociobiology, a subfield of Biology, some acquired qualities can affect genes and become inheritable over a long-term perspective.

The long list of scientific opinions presented above is an attempt to substantiate the causes that created the common characteristics of the inhabitants of Mani, as they have appeared over the two centuries that they began to leave the region and integrate into the structures and functions of the modern Greek state. Throughout the 25-year publishing journey of MANIOT SOLIDARITY, aspects of these common characteristics have been presented in our columns, and we believe that our compatriot readers recognise some of their own traits in them. Among these common characteristics are the impulsive tendencies to accept or reject many of the ongoing socio-political developments.

Systematic genomic comparisons of contemporary individuals with scientifically documented genomes from racial groups that history has recorded as having settled in our region during the Middle Ages and mixed with its Eleutherolakonian inhabitants could lead to conclusions about behavioural tendencies created on the basis of these racial affinities. Most importantly, however, these comparisons of the inhabitants of modern Mani and those who emigrated, with the genome of inhabitants of the region from 3-4 centuries ago, will undoubtedly reveal the multifaceted common characteristics found throughout the entire geographical area. This element, now substantiated, should lead to common actions by individuals with Maniot genetic roots to successfully addressing future challenges related to the promotion of our region.
