…also employed Bayesian age modeling of the mitochondrial genome, which estimated an age of ∼33,000–87,000 cal yr BP. Our taphonomic investigations show that the bison was scavenged post-mortem and infested…
…either the northern or southern Bahamas but discovered a relatively deep North-South divergence (~750 ka). This result, combined with radiocarbon dating and archaeological evidence, reveals a pre-human biogeographic divergence, and…
Examining skeletal traits within a time-calibrated phylogeny, the authors find that ocean geochemistry (particularly aragonite–calcite seas) has driven patterns of morphological evolution in anthozoans (corals, sea anemones) over time.
Avian diversification has been influenced by global climate change, plate tectonic movements, and mass extinction events. However, the impact of these factors on the diversification of the hyperdiverse perching birds…
…data from ultraconserved elements (UCEs) and whole mitochondrial genomes (i.e., mitogenomes) to explore genetic variation among allopatric populations of the weakly electric fish Sternopygus dariensis across the Isthmus of Panama….
…occurred since its formation. In Micranthes (Saxifragaceae), which has high rates of montane endemism, two species, M. bryophora and M. tolmiei, show this biogeographical pattern. By reconstructing a time-calibrated phylogeny…
…on the island until ca. 9,000 calibrated (cal) YBP [1]. Nevertheless, indigenous peoples, whose ancestors had trekked some 5,000 km from the west coast, arrived approximately 10,000 cal YBP in…
…relationships. Based on divergence times, the diversification at the backbone occurred near the Cretaceous-Paleogene (K-Pg) boundary (65 Mya) which is consistent with other rapid diversifications in the tree of life….
…from Krusza Zamkowa, Poland. To reconstruct kinship and determine biological sex, we extracted DNA from bones and teeth, analyzed mitochondrial genomes and nuclear SNPs using the HID-Ion AmpliSeq™ Identity panel…
