Cryptic diversification in ancient asexuals: evidence from the bdelloid rotifer Philodina flaviceps
Bdelloid rotifers, darwinulid ostracods and some oribatid mites have been called 'ancient asexuals' as they speciated and survived over long-term evolutionary timescale without sexual recombination. Data on their genetic diversification are contrasting: within-species diversification is pr...
