Unravelling DNA: Applying Christian Values to a Genetic Age

Gattaca and the quiet doomsday of genetic determinism

ABSTRACT Gattaca was a box-office disappointment when it was released in 1997. It has since become one of the most influential cultural texts to explore biotechnology and its social consequences, especially in a world where CRISPR-based gene editing, embryo screening, and consumer genomics are becoming more common. Gattaca is unique because its warning is not about genetic engineering technologies themselves, but about the ideology of genetic determinism or the belief that DNA defines human destiny. The film imagines a society in which a person’s worth, opportunities, and identity are determined exclusively by their genetic profile. Through its narrative, visual symbolism, and sterile futuristic aesthetics, Gattaca illustrates how genetic prophecy can reshape both social institutions and individual identity. The film anticipates a consumer-driven eugenics in which reproductive choices about genetic engineering are framed as responsible parenting. It shows how what begins as the pursuit of healthier children can become a discriminatory institutional system for ranking human value. Ultimately, Gattaca shows us a form of existential risk that is much different from sudden apocalyptic catastrophe. Its existential threat involves the slow erosion of the values that make human life meaningful: equality, self-determination, human diversity, and tolerance for imperfection.

The Overclocked Genome

The divergence between modern humans and archaic hominins such as Denisovans and Heidelbergensis is routinely presented as evidence for an evolutionary timescale spanning hundreds of thousands of years. This paper asks whether the number of substitutions arising on an archaic lineage can instead be accounted for by elevated paternal mutation input within a chronology derived from advanced ages of the patriarchs following the Flood that occurred just a few thousand years ago. Applying the paternal age dependence of the de novo mutation rate reported by Kong and colleagues (2012) to the patriarchal ages preserved in the Biblical text, I model a nine generation lineage descending from Shem and find that it accumulates approximately 29,747 de novo mutations, of which roughly 1,041 are classified as slightly deleterious but invisible to selection. Combined, this is approximately 98 percent of the figure of 31,389 that is frequently cited as the count of changes separating modern humans from archaic hominins. I then show that this figure, drawn from Pruefer and colleagues (2014), refers specifically to sites fixed on the modern human lineage while remaining ancestral in archaics, and is therefore neither a Denisovan branch quantity nor a measure of Denisovan diversity. I distinguish three quantities that are frequently merged in both creationist and evolutionary discussion, namely per generation mutation input, lineage divergence, and within population diversity, and I argue that a defensible young age model must aim its mechanism at the correct quantity. I further note that Denisovan and other archaic within population diversity is in fact extremely low, a result that favors a recently founded small population. I close by stating, in falsifiable terms, the objections the model must still answer.

Resequencing the Middle Ages through Archaeogenetics

Offering a clear and accessible introduction to the fast-growing field of archaeogenetics, this book pays particular attention to the methods and approaches that are reshaping how archaeologists and historians think about the past. Written for readers with no prior background in genetics, it explains in straightforward terms how genomic research can shed light on mobility, population change, social organization and cultural practices. At the same time, it begins with a critical reflection on the troubling history of attempts to fuse biology and history, showing how earlier racialized approaches distorted the past and warning against their resurgence today. By foregrounding both the current approaches and challenges of archaeogenetics, this book helps readers approach the field with a critical and informed perspective. The book’s central case study is the Carpathian Basin between 400 and 900 CE, which was a region at the crossroads of the transformation of the Roman world. Drawing on the most up-to-date research, this book demonstrates how integrating genomic, archaeological and historical data can illuminate the complex social and cultural changes of Late Antiquity and the early Middle Ages. The result is a concise yet compelling narrative of how cutting-edge science is reshaping medieval studies. Resequencing the Middle Ages is an introduction intended for archaeologists, historians, and a wider audience to how genomic data can be integrated into medieval archaeological and historical research. It begins with a cautionary account of the dark history of earlier attempts to integrate biological data into history that led to racial essentializing and warns of the danger of misuse of genetic analysis today. It then presents the integrated methodologies that are being used to avoid such tendencies while providing new, vital evidence of social processes in the past. It is written in a style that requires no previous knowledge of genetics and explains in a clear and non-technical manner the kinds of genomic methods currently being employed. By way of illustration, it surveys some of the most recent applications of ancientDNA analysis to early medieval Europe and then focuses on what such an integrated, interdisciplinary approach can contribute, drawing upon primarily upon research produced by the author and his colleagues who have conducted a major study of the Carpathian Basin between 400 and 900 CE. This project has produced numerous case studies that have appeared in scientific journals including Nature, Cell, PNAS, and Current Biology. The author weaves together these studies into a narrative illustrative of the transformation of the Roman world in this region. It concludes that the proper integration of genomics into historical research requires equal collaboration among humanists as well as natural scientists, with geneticists, historians, and archaeologists working as equals to analyse the past.

Why Evolution Has Failed the Sciences

The Neo-Darwinian synthesis asks us to accept that the biological distance separating humanity from an apelike common ancestor was crossed by nothing more than the accumulation and fixation of random genetic mutations, sifted across deep time by natural selection. This paper contends that the molecular evidence points decisively in the opposite direction. Rather than exhibiting the mutational openness that Darwinian change demands, the living cell is equipped with an elaborate, multi-layered apparatus whose measurable and undisputed function is to detect, excise, and reverse the very genetic alterations that evolution requires as its raw material. Over a dozen distinct DNA repair pathways operate continuously in somatic and germ line cells alike, correcting the overwhelming majority of the tens of thousands of lesions each cell sustains daily. The double helical architecture of DNA is itself a repair-ready design, storing two complementary copies of every base so that a damaged strand can be restored from its intact partner. Where a chromosome lacks a homologous partner, as with the male-specific Y chromosome, the genome supplies an ingenious alternative in the form of internal palindromic self-repair. I argue that a system engineered so comprehensively to prevent heritable change cannot plausibly be the engine of unlimited heritable change. The number of coordinated beneficial mutations required to convert an ape-like creature into a human being is so vast, and the waiting times so prohibitive, that molecules-to-man evolution is not merely improbable but effectively impossible. Life, in short, was designed not to evolve.

DNA Genealogy

DNA genealogy is a new field of science which considers patterns of mutations, which are different in different human lineages, in the DNA of present-day humans and of our ancient ancestors. Since the DNA is often preserved in ancient excavated bones, including those in archaeological burials, and can be recovered and studied, this approach allows us to compare the mutation patterns in the course of centuries and millennia. This in turn provides us with a knowledge of how often the mutations occur, that they are gradually changed over centuries and millennia, and, hence, calibrate the rate of mutations in various sites of the DNA in terms of time. In other words, it gives us a “molecular tool” aiming at establishing chronology of events along the ancient history of the humankind. Since the DNA is a molecule, DNA genealogy is also called the “Molecular History”. This is a subject of this book. The book begins with an explanation of what is a nature of mutations in the DNA, why the mutations are random, how to measure their rates, in terms of how many mutations occur in the DNA over centuries and millennia, therefore, to calculate their mutation rate constants. This first part of the book provides the reader with many examples of how DNA genealogy employs the mutation rates to uncover hidden puzzles of ancient human history, such as when Homo sapiens first appeared, who were ancient Europeans, Asians, Africans, Americans compared with their present-day descendants in terms of their DNA lineages, and introduces a rather simple calculator which everyone can run on their personal computer devices, iPhones, etc. to conduct such calculations of ancient chronology. Subsequent chapters of the book consider such controversial issues as whether early people came “out of Africa” or “into Africa” (both hypotheses have their supporters among scientists), who were the ancient Aryans and why their language obtained – much later – a name “Indo-European”, where was a homeland of a majority of nowadays Europeans and Native Americans (a hint – South Siberia), who were ancient Jews and Arabs and when their actual common ancestor lived, what DNA was revealed from a few Khazar burials, why look-alike ancient ceramics, made many thousand years ago, was found both in Europe and Asia, how ancient and contemporary languages are connected with the DNA of people, both ancient and contemporary. The book is targeted for multidisciplinary scientists as well as students and advanced general readership.
