Abstract：
Does genetic background contribute to populations following the same or divergent adaptive trajectories? A recent study by Filipow et al. evolved multiple genetically distinct Pseudomonas aeruginosa strains to an artificial cystic fibrosis lung sputum media. The strains adapted at different rates but converged on similar phenotypes despite their initial diversity.

遗传背景是否有助于种群遵循相同或不同的适应轨迹？Filipow等人最近的一项研究。将多种遗传上不同的铜绿假单胞菌菌株进化为人工囊性纤维化肺痰培养基。尽管最初具有多样性，但菌株以不同的速率适应，但收敛于相似的表型。
