The primate-specific noncoding RNA HPAT5 regulates pluripotency during human preimplantation development and nuclear reprogramming by Jens Durruthy-Durruthy, Vittorio Sebastiano, et al., Nature Genetics. Genetic residue from ancient viral infections has been repurposed to play a vital role in acquiring pluripotency, the developmental state that allows a fertilized human egg to become all the cells in the body.Īncient viral molecules essential for human development by Krista Conger, Stanford Medicine (+ ).

Ī huge chunk of a tardigrade's genome comes from foreign DNA, University of North Carolina. Evidence for extensive horizontal gene transfer from the draft genome of a tardigrade, Thomas C. ![]() Īpproximately one-sixth of the genes in the tardigrade genome were found to have been acquired through horizontal transfer. No evidence for extensive horizontal gene transfer in the genome of the tardigrade Hypsibius dujardini, Georgios Koutsovoulos et al., doi:10.1073/pnas.1600338113, PNAS, online. How Much Foreign DNA Tardigrades Actually Have by Victoria Turk, Motherboard. The genome of the tardigrade Hypsibius dujardini, Georgios Koutsovoulos et al., doi:10.1101/033464, BioR xiv, and commentary: We compare our assembly to a recently published one for the same species and do not find support for massive horizontal gene transfer. For example, see New genetic programs in Darwinism and strong panspermia. They are a basic prediction of cosmic ancestry. Standard darwinism is perplexed by genetic programs that seem to have come from nowhere. ![]() Newman, Professor of Cell Biology and Anatomy, New York Medical College: Many triploblast groups are associated with an entirely new collection of previously nonexistent proteins, mediating previously unprecedented functions. The arrival of this new group was accompanied by a small number of novel proteins (specified by previously nonexistent genes). ![]() The Senior Astronomer at SETI says that an apparent biological fossil on Mars can be ruled nonbiological by geologists, with no need to consult biologists, 13. ![]() Promiscuous DNA: horizontal transfer of transposable elements and why it matters for eukaryotic evolution by Sarah Schaack, Clément Gilbert and Cédric Feschotte, doi:10.1016/j.tree.2010.06.001, Trends Ecol Evol, Sep 2010. We argue that the introduction of transposable elements by horizontal transfer in eukaryotic genomes has been a major force propelling genomic variation and biological innovation. (Rebuttal) Horizontal gene transfer is not a hallmark of the human genome, by Steven L. Expression of multiple horizontally acquired genes is a hallmark of both vertebrate and invertebrate genomes by Alastair Crisp, Chiara Boschetti et al., doi:10.1186/s1305-3, Genome Biol. We identified up to hundreds of active foreign genes in animals, including humans, suggesting that HGT provides important contributions to metazoan evolution. Viruses and Other Gene Transfer Mechanisms is the main related CA webpage. Horizontal transfer of short and degraded DNA has evolutionary implications for microbes and eukaryotic sexual reproduction by Søren Overballe-Petersen and Eske Willerslev, doi:10.1002/bies.201400035, Bioessays, Oct 2014. It is even argued that HGT has been highly active and important since the beginning of cellular life and that the complexity of life, as we know it, may not have evolved without HGT.
