For close to 30 years, Dr. Frank
Ryan has investigated theoretical evolutionary biology. In this
conversation he discusses the genomic creativity of virus-host
coevolution.
Listeners will hear Dr. Ryan recount
Author Dr. Frank Ryan is Honorary Senior Lecturer of the Department
of Medical Education at the University of Sheffield, UK, and an
emeritus consulting physician with the affiliated Sheffield
Teaching Hospitals. He's also a Fellow of the Royal Colleges of
Physicians of England and a Fellow of the Royal Society of Medicine
and the Linnaean Society of London.
He recounts incidences of genomic creativity from his research into symbiont viruses and host coevolution. Early in his academic career, he studied bacteria phages in rabbits, and thus began a lifelong interest. He discusses relevant findings such as the mechanics of the coronavirus and its use of the host's ribosomes to replicate itself.
As he discusses the behavior of symbiont viruses, he explains how a virus like AIDS uses a selective pressure on its hosts through survival rates. He explains that if there were no medical involvement, Aids would have changed the human genome to benefit itself.
Finally, he talks about such controversial issues as the consideration of viruses as living vs. nonliving and explains what the ocean would like without viruses to keep the bacterial population in check.
