Beefalo Genomes Challenge Three-Eighths Standard, Uncover Zebu Influence

Beefalo Genomes Challenge Three-Eighths Standard, Uncover Zebu Influence

A genome-wide study of 47 Beefalo semen samples from founding lines shows 39 animals have no detectable bison ancestry, calling into question the breed standard of three-eighths bison; the eight with bison DNA show only 2–18% ancestry. The analysis also reveals widespread zebu ancestry in 38 of the animals, including Joe’s Pride, which was recorded as over a third bison. The researchers suggest zebu introgression may have shaped the breed’s appearance and that backcrossing patterns explain how bison DNA could appear in a largely taurine/cattle background. Using preserved germplasm and multiple genomic approaches, the study provides a genomic audit that pedigrees alone could not reliably establish the breed’s composition.

America’s Ancestry by Neighborhood: A Live Map of Our Roots

NYT’s interactive map uses the Census Bureau’s 2019–2024 American Community Survey to show how Americans identify their ancestry across the country. Tap any area to see the blend of origins, with colors representing mixed ancestries. Data allow multiple ancestries and percentages may not sum to 100, with figures rounded; read more for full context.

DNA Reveals Rare Twin with Different Fathers

DNA Reveals Rare Twin with Different Fathers

Two UK twins, Lavinia and Michelle, discover they share a womb but have different fathers due to heteropaternal superfecundation after taking Ancestry DNA tests—a rare finding that reshapes their identities, leads Lavinia to meet her biological dad Arthur Moon Foot, and brings Michelle into a wider network of half-siblings. The piece follows their difficult upbringing, the emotional fallout of the revelations, and how casual home DNA testing is increasingly exposing hidden family histories.

UK twins uncover two fathers after DNA test, a rare biological twist

Two British twins, Michelle and Lavinia Osbourne, learned via Ancestry DNA testing that they have different biological fathers—a phenomenon called heteropaternal superfecundation that is extremely rare, with only about 20 cases documented worldwide and none previously in British history; the sisters say the discovery doesn’t alter their close bond as they continue to live in England.

DNA Rewrites Beachy Head Woman’s Origins: Local to Roman Britain

DNA analysis of the Beachy Head Woman, a Roman-era skeleton found near Beachy Head, shows she was likely local to the Roman Britain population, revising earlier guesses of Sub-Saharan African or Mediterranean ancestry; improved DNA techniques also updated her facial reconstruction to reflect light skin, blue eyes, and fair hair, placing her life along the Roman coastal landscape (129–311 AD) and underscoring how genetics can revise archaeological narratives.

Ancestry at the Center of the Birthright Citizenship Case

Ancestry at the Center of the Birthright Citizenship Case

Nine Supreme Court justices will decide whether birthright citizenship under the Fourteenth Amendment endures after President Trump's 2025 executive order to end automatic citizenship for children born to undocumented immigrants or people in the U.S. on temporary visas; lower courts have blocked the measure. The piece also traces each justice's ancestry—from Roberts' English and Slovak roots to Sotomayor's Puerto Rican heritage and Jackson's enslaved-African lineage—showing how personal histories intersect with this defining constitutional question.

Countries Offering Ancestry-Based Citizenship for Americans Post-Trump

Following the 2024 presidential election, many Americans, including celebrities, are considering leaving the U.S. and exploring dual citizenship options. Nine countries—Ghana, Germany, Hungary, India, Ireland, Italy, Poland, Portugal, and Spain—offer pathways to citizenship based on ancestry, allowing individuals to claim nationality through parents, grandparents, or direct ancestors. These countries provide various benefits and requirements for those seeking to reconnect with their heritage or obtain a second passport.

Uncovering Charleston's Legacy of Slavery through DNA Analysis

In Charleston, S.C., a project to collect DNA from Black residents has evolved into a search for living descendants of 36 enslaved people whose bones were discovered by a construction crew. Despite initial skepticism due to historical exploitation, participants like Edward Lee have been swabbed for DNA, hoping to uncover clues about their ancestry and history. The project aims to provide Black residents with new insights into their heritage and connections to the region's history of slavery.

"The Genetic Ancestry of Every Blue-Eyed Person Traces Back to a Single Human Ancestor"

"The Genetic Ancestry of Every Blue-Eyed Person Traces Back to a Single Human Ancestor"

Every person with blue eyes on Earth is a descendant of one single human who lived between 6,000 and 10,000 years ago, as a genetic mutation from the HERC2 gene completely turns off the OCA2 gene, diluting brown pigment into blue. This discovery, made in 2008, suggests that all blue-eyed individuals share a common ancestor and that the mutation likely spread when humans migrated from Africa to Europe. The study also explains the rarity of blue eyes, estimating that 8 to 10 percent of the world's population have them, mainly among people of European descent.
