Birds are the only dinosaur lineage that survived until today. About 66 million years ago at the Cretaceous–Paleogene (K–Pg) boundary, a mass extinction event destroyed all non-avian dinosaurs, providing an opportunity for birds to diversify rapidly and occupy a wide range of ecological niches. Neoaves, a diverse group comprising approximately 95% of all bird species today, emerged from this radiation. From the towering condors of the Andes to the diminutive hummingbirds flitting through tropical forests, Neoaves encompass a stunning ...

Microsatellites are valuable tools for studying inheritance, genetic diversity, and population dynamics across a wide range of organisms including bacteria, plants, animals, and fungi. These short, repeating sequence motifs are a common feature of both coding and non-coding DNA and have been observed in all genomes studied to date. Their repetitive nature leads to “slippage” in the DNA replication machinery, resulting in the addition or subtraction of repeats that causes microsatellites to grow or shrink in length. Because of this, there is considerable variability ...
