The effect of sex on the repeatability of evolution in different environments

摘要: The adaptive function of sex has been extensively studied, while less consideration given to the potential downstream consequences on evolution. Here, we investigate one such consequence, effect repeatability By affecting evolution, could have important implications for biodiversity, and our ability make predictions about outcome environmental change. We allowed asexual sexual populations Chlamydomonas reinhardtii evolve in novel environments monitored both their change fitness variance after Sex affected evolution by changing importance selection, chance, ancestral constraints evolutionary process. In particular, effects were highly dependent initial genetic composition population environment. Given lack a consistent across used here, further studies dissect more detail underlying reasons these differences as well additional are required if general understanding
