| divergent and parallel routes of biochemical adaptation in high-altitude passerine birds from the qinghai-tibet plateau. | when different species experience similar selection pressures, the probability of evolving similar adaptive solutions may be influenced by legacies of evolutionary history, such as lineage-specific changes in genetic background. here we test for adaptive convergence in hemoglobin (hb) function among high-altitude passerine birds that are native to the qinghai-tibet plateau, and we examine whether convergent increases in hb-o2 affinity have a similar molecular basis in different species. we docum ... | 2018 | 29432191 |
