The emergence of life from non-living matter remains one of the most profound unresolved questions in natural philosophy. Classical models derived from the Oparin-Haldane hypothesis assume a gradual (sequential), selective assembly of biological precursors. Yet, for more than a century, all experimental efforts in this direction have failed in their attempt to achieve material abiogenesis. May be [...]
Unlocking the hidden dimensions of genomic diversity within species
Published: 2024-12-16
Subjects: Evolution, Genomics, Molecular Biology
The missing heritability problem, defined as the failure of genetic variants to explain variance in phenotypes, has been an unsolved issue in genetics for the past two decades. A potential solution to this problem stems from the idea that single nucleotide polymorphisms and copy-number variants, the most commonly studied forms of genomic diversity, do not represent the totality of the information [...]
Hijackers, hitchhikers, or co-drivers? The mysteries of microbial mobilizable genetic elements
Published: 2024-04-26
Subjects: Bacteriology, Evolution, Genetics, Life Sciences, Molecular Biology
Mobile genetic elements shape microbial gene repertoires and population dynamics, but their mechanisms of horizontal transmission are often unknown. Recent results reveal that many, possibly most, bacterial mobile genetic elements require helper elements to transfer between (or within) genomes. We refer to these non-autonomous, albeit mobile, elements as Hitcher Genetic Elements (hitchers or [...]

On May 16, 2020, the Center for Academic Research and Training in Anthropogeny organized the symposium “Impact of Infectious Disease on Humans and Our Origins”. The symposium aimed to gather experts on infectious diseases in one place and discuss the interrelationship between different pathogens and humans in an evolutionary context. The talks discussed topics including SARS-CoV-2, dengue and [...]
