Abstract: Human activities have changed the biosphere that many have called to name this new time period the Anthropocene. The investigation of conspecific populations at different time points may shed light on the magnitude of human-mediated changes to the genome. We implemented ancient-DNA protocols and retrieved whole genomes from museum specimens for both time comparison and supplementation of currently rare taxa. We analysed genomes of the red junglefowl and the white-rumped shama complex to test the hypothesis that anthropogenic activities have greatly affected and changed the genomes of these bird groups. By comparing chickens and junglefowl, we found an increased in domestic contribution overtime. For the shama, we also found a significant decrease in genetic diversity and a concomitant increase in homozygosity affecting various taxa when comparing samples from a 100 years ago with modern samples. Both study systems illustrate the deleterious effects that the Anthropocene has on biodiversity.
