Understanding how the dispersal of cultural innovations intersects with the spread of genes remains a central challenge in prehistoric archaeology. Here, we examine how the third millennium BCE Corded Ware (CW) and Bell Beaker (BB) burial traditions disseminated across Europe and their relation to the influx of steppe ancestry. To investigate these spatiotemporal dynamics during one of Europe's most transformative periods, we compiled a dataset of radiocarbon dates from 967 burials, applying kernel density estimation alongside optimal linear estimation. We show that the adoption of CW and BB funerary rites is not synchronized with, and often contradicts, the spread of steppe ancestry. Furthermore, we show that these burial traditions spread rapidly and polyfocally among dispersed communities before a brief yet continent-wide consolidation phase around 2600 BCE for CW and 2400 BCE for BB, suggesting broad, simultaneous societal changes among preliterate societies.

Loss and fragmentation of habitat from agricultural conversion led to the near extirpation of the pygmy rabbit ( Merriam, 1891) population in the Columbia Basin (CB) of Washington, USA. Recovery efforts began in 2002 and included captive breeding, translocations from other regions for genetic rescue, and reintroduction into native habitat in three sites: Sagebrush Flat (SBF), Beezley Hills (BH), and Chester Butte (CHB). We used noninvasive and invasive genetic sampling to evaluate demographic and population genetic parameters on three translocated populations of pygmy rabbits over eight years (2011-2020).

The transition from the Bronze Age (BA) to the Iron Age (IA) on the Northeastern Iberian Peninsula is characterized by the emergence of cremation as the main funerary practice. Cultural attributes of a group, known as the Urnfield Culture, expanded from Central Europe to Northeastern Iberia during the Final Bronze Age (FBA), from ~1300 to ~850 cal BCE. Various hypotheses on the group's emergence exist, but cremations hinder DNA preservation.

Genetic evaluations are predicated on routine access to large quantities of data on a range of performance traits from individual animals, their genetic relationships, as well as data on the factors other than additive genetic merit that influence phenotypic performance. Based on the well-established breeding pyramid, far more commercial animals generally exist relative to seedstock animals. Despite this, performance data from commercial animals is not always used in genetic evaluations.

Background: Recent ancient DNA studies uncovering large-scale demographic events in Iberia have presented very limited data for Portugal, a country located at the westernmost edge of continental Eurasia. Here, we present the most comprehensive collection of Portuguese ancient genome-wide data, from 67 individuals spanning 5000 years of human history, from the Neolithic to the nineteenth century.
Results: We identify early admixture between local hunter-gatherers and Anatolian-related farmers in Neolithic Portugal, with a northeastern-southwestern gradient of increasing Magdalenian-associated ancestry persistence in Iberia.
