Summary

Story summary

Hybridization between domestic pigs and wild boars in Fukushima after the 2011 disaster has created a hybrid population.
The study, led by Shingo Kaneko, finds that maternal pig lineages accelerate genetic turnover in wild boars.
The researchers show hybrid boars inherit rapid reproductive cycles from domestic pigs, causing quicker generational turnover.
The findings may inform similar studies globally and aid in managing invasive species.
