Theory predicts that parallel evolution should be common when the number of beneficial mutations is limited by selective constraints on protein structure. [...] Key Result One to five amino acid replacements were significantly overrepresented or derived in each highland population, and parallel substitutions were more common than in simulated sequences evolved under a neutral model.Expand
Stepwise colonization of the Andes by Ruddy Ducks and the evolution of novel β‐globin variants
TLDR
It is suggested that ruddy ducks first acclimatized or adapted to the Andean highlands and then again to the lowlands, via a less common route as compared to other waterbird species that colonized the Andes northwards from the southern cone of South America. Expand
Convergent Evolution of Hemoglobin Function in High-Altitude Andean Waterfowl Involves Limited Parallelism at the Molecular Sequence Level
TLDR
A comparative analysis of hemoglobin (Hb) function in eight phylogenetically replicated pairs of high- and low-altitude waterfowl taxa shows that convergent changes in protein function can occur through multiple historical paths, and can involve multiple possible mutations. Expand
Adaptive introgression of the beta-globin cluster in two Andean waterfowl.
TLDR
It is found that identical amino acid substitutions in the β-globin cluster that increase Hb-O2 affinity have likely resulted from historical interbreeding between high-altitude populations of two different distantly-related species. Expand
Multilocus coalescent analysis of haemoglobin differentiation between low‐ and high‐altitude populations of crested ducks (Lophonetta specularioides)
TLDR
The combined effects of selection and population history on inferring levels of population divergence for a species distributed across an altitudinal gradient in which selection for hypoxia resistance has likely played an important role is illustrated. Expand
Integrating evolutionary and functional tests of adaptive hypotheses: a case study of altitudinal differentiation in hemoglobin function in an Andean Sparrow, Zonotrichia capensis.
TLDR
A combined functional and evolutionary analysis of Hb polymorphism in the rufous-collared sparrow, a species that is continuously distributed across a steep elevational gradient on the Pacific slope of the Peruvian Andes, demonstrated that the observed amino acid mutations have no discernible effect on respiratory properties of the HbA or HbD isoforms.

Phylogenetic and structural analysis of the HbA (alphaA/betaA) and HbD (alphaD/betaA) hemoglobin genes in two high-altitude waterfowl from the Himalayas and the Andes: Bar-headed goose (Anser indicus) and Andean goose (Chloephaga melanoptera).
TLDR
P phylogenetic analyses of the swans and geese and South American sheldgeese using the three genes that encode the major (HbA) and minor (HBD) hemoglobin isoforms produced well-resolved phylogenies, with high posterior probabilities and bootstrap values for most genera. Expand
Using seasonal genomic changes to understand historical adaptation to new environments: Parallel selection on stickleback in highly‐variable estuaries
TLDR
The genomic changes that occur in threespine stickleback from bar‐built estuaries could provide a glimpse into the early stages of adaptation that have occurred in many historical marine to freshwater transitions. Expand

TLDR
The genomic changes that occur in threespine stickleback from bar-built estuaries could provide a glimpse into the early stages of adaptation that have occurred in many historical marine to freshwater transitions. Expand
GENETIC AND PHENOTYPIC DIVERGENCE BETWEEN LOW‐ AND HIGH‐ALTITUDE POPULATIONS OF TWO RECENTLY DIVERGED CINNAMON TEAL SUBSPECIES
TLDR
Genetic and phenotypic patterns of divergence between low‐ and high‐altitude populations of cinnamon teal inhabiting normoxic and hypoxic regions in the Andes and adjacent lowlands of South America indicated that the highlands were most likely colonized from lowland regions but following divergence, gene flow has been asymmetric from the highland into the lowlands. Expand
Speciation, Subspecies Divergence, and Paraphyly in the Cinnamon Teal and Blue-Winged Teal
TLDR
Examination of the evolutionary history of two closely related waterfowl, the Cinnamon Teal and Blue-winged Teal, finds that these taxa diversified rapidly, and analyses of isolation with migration indicated that sharing of haplotypes and alleles in the two continents is more likely attributable to incomplete lineage sorting than to gene flow.

Signatures of High‐Altitude Adaptation in the Major Hemoglobin of Five Species of Andean Dabbling Ducks
Hypoxia is one of the most important factors affecting survival at high altitude, and the major hemoglobin protein is a likely target of selection. We compared population genetic structure in the αAExpand

The discovery that allelic differences in DPG-sensitivity contribute to adaptive variation in hemoglobin–O2 affinity illustrates the value of integrating evolutionary analyses of sequence variation with mechanistic appraisals of protein function. Expand
Adaptation of bird hemoglobins to high altitudes: demonstration of molecular mechanism by protein engineering.
TLDR
Possession of a Hb with high oxygen affinity helps to adapt bar-headed and Andean geese to high altitudes by introducing each of these substitutions into human globin synthesized in Escherichia coli, which combines cooperatively with oxygen. Expand
Frequent and widespread parallel evolution of protein sequences.
TLDR
The role of homoplasy in shaping the protein record is much larger than generally assumed, and it is suggested that its high frequency can be explained by both weak positive selection for certain substitutions and purifying selection that constrains substitutions to a small number of functionally equivalent amino acids.

Parallel Genetic Evolution Within and Between Bacteriophage Species of Varying Degrees of Divergence
TLDR
By adapting three related bacteriophage species to a novel environment, a high rate of parallel genetic evolution at orthologous nucleotide and amino acid residues within species is found and the probability of parallel and convergent evolution between species is strongly effected by divergence. Expand
Gene flow in the face of countervailing selection: adaptation to high-altitude hypoxia in the betaA hemoglobin subunit of yellow-billed pintails in the Andes.
TLDR
It is hypothesized that migration between the lowlands and highlands is restricted by local adaptation, and the betaA hemoglobin subunit is a likely target of selection related to high-altitude hypoxia; however, gene flow may be sufficiently high to retard divergence at most unlinked loci. Expand

TLDR
It is suggested that most haemoglobins possess an additional phosphate binding site, having such a role in oxygen transport, and may act as an entry/leaving site, thus increasing the probability of capturing phosphate and transferring it to the main binding site located between the two beta chains.
