In the course of evolution, animals have repeatedly shifted from sexual to asexual reproduction. The first evidence of the consequences of parthenogenesis – a type of asexual reproduction – on genome evolution is reported in an international study co-led by scientists at UNIL and SIB. The findings help to explain why species reproducing in this way are generally more vulnerable in the wild, where environments change continuously. The study is published today in Science Advances.
