Article Synopsis
- The paradox of the great speciators describes a conflicting pattern in avian lineages in Oceania that shows broad geographic distributions indicative of strong dispersal, yet also displays significant genetic divergence suggesting limited inter-island movement.
- A study using genomic sequencing of dwarf kingfishers from northern Melanesia found deep genetic divergence and an absence of gene flow between nearby island populations, highlighting the paradox effectively.
- The research proposes a framework based on founder effects and changing selection pressures that explains how diverse traits and environmental factors influence dispersal capabilities, shedding light on the evolutionary dynamics of these bird lineages.
Body size is a key morphological attribute, often used to delimit species boundaries among closely related taxa. But body size can evolve in parallel, reaching similar final states despite independent evolutionary and geographic origins, leading to faulty assumptions of evolutionary history. Here, we document parallel evolution in body size in the widely distributed leaf-nosed bat genus Hipposideros, which has misled both taxonomic and evolutionary inference.
