“…The first explanation (introgression) is most common for nuclear sister species with divergent mtDNA 4 , 12 . In this study, we test whether the anomalous mtDNA divergence of the closely related wisent and bison 13 originated as a result of ancient introgression or ILS.…”

“…Intriguingly, the wisent and American bison are morphologically similar and cross-fertile and have closely related nuclear genes 17 , 18 , but the mtDNA phylogeny consistently clusters the wisent with the lineage leading to taurine cattle and zebu 19 . Recently, this has been studied in more detail on the basis of ancient DNA and/or whole-genome sequences (WGS) 13 . Wecek et al 20 and Gautier et al 21 found that a small but variable part of the wisent genome originated from domestic cattle.…”

The wisent or European bison is the largest European herbivore and is completely cross-fertile with its American relative. However, mtDNA genome of wisent is similar to that of cattle, which suggests that wisent emerged as a hybrid of bison and an extinct cattle-like species. Here, we analyzed nuclear whole-genome sequences of the bovine species, and found only a minor and recent gene flow between wisent and cattle. Furthermore, we identified an appreciable heterogeneity of the nuclear gene tree topologies of the bovine species. The relative frequencies of various topologies, including the mtDNA topology, were consistent with frequencies of incomplete lineage sorting (ILS) as estimated by tree coalescence analysis. This indicates that ILS has occurred and may well account for the anomalous wisent mtDNA phylogeny as the outcome of a rare event. We propose that ILS is a possible explanation of phylogenomic anomalies among closely related species.

“…This situation was achieved only around 2016 when the genome of the extant B. bonasus (wisent) was sequenced [7,8], partial genomic information from historical specimens was obtained [9] and ancient Bison specimens from the Upper Pleistocene and the Holocene in Eurasia yielded sequencing results [10][11][12]. As a consequence, 2016 was declared the year of the wisent [13]. Likewise, in 2017, paleogenetic data focusing on the evolution of the B. priscus lineage in the American continent were produced [1].…”

The Evolution and Population Diversity of Bison in Pleistocene and Holocene Eurasia: Sex Matters

et al. 2018

Knowledge about the origin and evolutionary history of the bison has been improved recently owing to several genomic and paleogenomic studies published in the last two years, which elucidated large parts of the evolution of bison populations during the Upper Pleistocene and Holocene in Eurasia. The produced data, however, were interpreted in contradicting manners. Here, we have gathered, reanalyzed and compared previously published or unpublished morphometric and genetic data that have not yet been integrated and that we synthesize in a unified framework. In particular, we re-estimate dates of divergence of mitogenome lineages based on an extended dataset comprising 81 complete ancient bison mitogenomes and we revisit putative gene flow between the Bos and Bison genera based on comparative analyses of ancient and modern bison genomes, thereby questioning published conclusions. Morphometric analyses taking into account sexual dimorphism invalidate a previous claim that Bison schoetensacki was present in France during the Late Pleistocene. Both morphometric and genome analyses reveal that Eurasian bison belonging to different Bison priscus and Bison bonasus lineages maintained parallel evolutionary paths with gene flow during a long period of incomplete speciation that ceased only upon the migration of B. priscus to the American continent establishing the American bison lineage. Our nuclear genome analysis of the evolutionary history of B. bonasus allows us to reject the previous hypothesis that it is a hybrid of B. priscus and Bos primigenius. Based on present-day behavioral studies of European and American bison, we propose that apparently conflicting lines of evidence can be reconciled by positing that female bison drove the specialization of bison populations to different ecological niches while male bison drove regular homogenizing genetic exchanges between populations.

“…), goat (Capra hircus) and sheep (Ovis aries). We also find reads classified as wisent (Bison) and buffalo (Bubalus), however, both species and their geographical distribution in this area remains debated (34)(35)(36)(37) (38)(39)(40), and reads could likely be missing or represent past genetic diversity from the taurine cattle found in the same layers. We therefore extracted all reads classified to each genus and blasted these against the nucleotide database (NCBI, RefSeq databases) using blastn (41) (see Methods).…”

Central European forests have been shaped by complex human interactions throughout the Holocene, with significant changes following the introduction of domesticated animals in the Neolithic (∼7.5 – 6.0 kyr BP). However, understanding early pastoral practices and their impact on forests is limited by methods for detecting animal movement across past landscapes. Here we examine ancient sedimentary DNA (sedaDNA) preserved at the Velký Mamuťák rock shelter, in northern Bohemia (Czech Republic), which has been a forested enclave since the early Holocene. We find that domesticated animals, their associated microbiomes, and plants potentially gathered for fodder, have clear representation by the Late Neolithic, around 6.0 kyr BP, and persist throughout the Bronze Age into recent times. We identify a change in dominant grazing species from sheep to pigs in the Bronze Age (∼4.1 – 3.0 kyr BP) and interpret the impact this had in the mid-Holocene retrogressions that still define the structure of Central European forests today. This study highlights the ability of ancient metagenomics to bridge archaeological and paleoecological methods and provide an enhanced perspective on the roots of the Anthropocene.
