适应生态上独特的环境可能与生殖障碍的出现同时发生。这一过程的结果是高度可变的，并且可以沿着一个连续体从弱的群体分化一直到完全的全基因组分化。决定分歧类群将沿着沿着这一连续体移动多远的因素仍然知之甚少，但在重复分歧类群中进行的研究最有益。在这里，我们通过比较年轻人的表型和分子差异来探索物种形成的决定因素（
Adaptation to ecologically distinct environments can coincide with the emergence of reproductive barriers. The outcome of this process is highly variable and can range along a continuum from weak population differentiation all the way to complete, genome-wide divergence. The factors determining how far diverging taxa will move along this continuum remain poorly understood but are most profitably investigated in taxa under replicate divergence. Here, we explore determinants of progress towards speciation by comparing phenotypic and molecular divergence within young (
