Ancient DNA suggests drastically different evolutionary history for modern and extinct sloths

New mitochondrial genomes for extinct sloths suggests a very different evolutionary path for giant ground and Caribbean sloths.

Evolution of the Mylodontidae and Arborealism in Sloths

Nuclear and mitochondrial data from Darwin's extinct ground sloth shows close relation to two-fingered sloths and supports multiple origins for arboreality.

Ancient DNA and Isotopes Reveal Roman Italian Ancestry and Family Relationships

McMaster Researcher reveal complex population dynamics in the wake of Roman subjugation of the Italian Peninsula (3rd century BCE)

Whole genomes reveal messy history of promiscuous proboscideans

A new collaboration between researchers at the McMaster Ancient DNA Centre and international researchers from across the United States, Europe, and Australia has resulted in the most comprehensive study of elephant evolution to-date.

Testing the validity of stable isotope analyses of dental calculus as a proxy in paleodietary studies

Stable isotopic analyses (δ13C, δ15N) of dental calculus have been suggested as a proxy for the study of diet of ancient populations but questions about their validity have been raised.

The paradox of HBV evolution as revealed from a 16th century mummy

Hepatitis B virus (HBV) is a ubiquitous viral pathogen associated with large-scale morbidity and mortality in humans. However, there is considerable uncertainty over the time-scale of its origin and evolution.

Genetic Discontinuity between the Maritime Archaic and Beothuk Populations in Newfoundland, Canada

By examining the mitochondrial genome diversity and isotopic ratios of 74 ancient remains in conjunction with the archaeological record, we have provided definitive evidence for the genetic discontinuity between the maternal lineages of these populations. This northeastern margin of North America appears to have been populated multiple times by distinct groups that did not share a recent common ancestry, but rather one much deeper in time at the entry point into the continent.

A molecular portrait of maternal sepsis from Byzantine Troy

Pregnancy complications are poorly represented in the archeological record, despite their importance in contemporary and ancient societies. While excavating a Byzantine cemetery in Troy, we discovered calcified abscesses among a woman’s remains.

17th Century Variola Virus Reveals the Recent History of Smallpox

The partially mummified remains of a young child have offered a unique insight into the history of a once-feared disease. The remains, recovered from the crypt of the Dominican Church of the Holy Spirit in Vilnius, Lithuania, have been dated to the mid-17th century.
