Two studies have found that analyzing the timing of horizontal gene transfer events can help date microbial phylogenies.
Using haplotype profiling, phylogenetics, and other analyses, researchers retraced sickle allele emergence to a single event occurring roughly 7,300 years ago.
Researchers report on a genetic analysis of ravens that indicates a species reversal event took place, according to the Guardian.
