在相似环境中相似表型的快速进化，引起原地平行适应，是生态物种形成的一个重要标志。然而，似乎是在原地适应也可能出现分散不同的谱系从其他地方。我们测试是否两个对比的表型重复平行进化，或有一个单一的起源，在一个典型的例子，生态适应辐射：底栖湖沼三棘鱼（Gasterosteus aculeatus）在不列颠哥伦比亚省的物种对和孤立的湖泊。我们确定了两个基因组集群在淡水种群，不同的底栖湖沼不同的表型性状和分离的底栖湖沼物种对湖泊的个人。系统发育重建和生态位进化建模都表明这些集群中的每个集群都有一个单一的进化起源。我们检测到强烈的系统发育信号在底栖湖沼趋异性状，这表明他们是祖先保留。占祖先的状态保留，我们确定当地的适应防弹衣由于存在的intraguild捕食者，杜父鱼（杜父鱼），和环境的影响，湖泊深度和pH值对身体的大小。两者合计，我们的研究结果意味着一个主要的作用，为保留祖先的特点，在驾驶性状分布，与进一步的选择施加在一些性状的环境因素。
Rapid evolution of similar phenotypes in similar environments, giving rise to in situ parallel adaptation, is an important hallmark of ecological speciation. However, what appears to be in situ adaptation can also arise by dispersal of divergent lineages from elsewhere. We test whether two contrasting phenotypes repeatedly evolved in parallel, or have a single origin, in an archetypal example of ecological adaptive radiation: benthic–limnetic three-spined stickleback (Gasterosteus aculeatus) across species pair and solitary lakes in British Columbia. We identify two genomic clusters across freshwater populations, which differ in benthic–limnetic divergent phenotypic traits and separate benthic from limnetic individuals in species pair lakes. Phylogenetic reconstruction and niche evolution modeling both suggest a single evolutionary origin for each of these clusters. We detected strong phylogenetic signal in benthic–limnetic divergent traits, suggesting that they are ancestrally retained. Accounting for ancestral state retention, we identify local adaptation of body armor due to the presence of an intraguild predator, the sculpin (Cottus asper), and environmental effects of lake depth and pH on body size. Taken together, our results imply a predominant role for retention of ancestral characteristics in driving trait distribution, with further selection imposed on some traits by environmental factors.
