Natural-born divers and the molecular traces of evolution
Date:6/28/2009

to the charge of its individual amino acids, and therefore it can be predicted if the amino acid sequence is known. Dr. Berenbrink's team have determined large parts of the myoglobin sequence for four different species of insectivores, and combined it with the analysis of already published sequences from other species to reach their conclusions. They were careful to select species with close terrestrial relatives that could be used as a natural control group during the sequence comparison, so that differences at the molecular level could be safely assumed to be the product of their habitat preference. "This work will contribute to our understanding of protein solubility in general", explains Dr.Berenbrink. "It will also allow the analysis of natural selection on protein structure/function in multiple parallel cases in which a high muscle myogobin content evolved, such as in divers but also in burrowing animals that normally experience hypoxia".
