Ötzi Ice Man, The Titanic, The Romanovs – Case Study

Ötzi Ice Man

• Ötzi Ice Man: discovery

  • Discovered by German hikers taking a shortcut in the Ötztal Alps, Italy.

  • Human corpse found in a gully; only partly uncovered and surrounded by other items.

• Recovery conditions

  • Took $4$ days to recover the corpse due to bad weather.

  • Body was in a gully at an altitude of $3{,}210 \, \text{m}$ above sea level.

  • Large boulders had protected the body from environmental conditions.

  • Extremely lucky to have been found at all.

• Excavation and associated items

  • Two archaeological digs were required to find all items associated with the body.

  • Steam jets were used to melt the snow and ice.

  • Items recovered: leather, hide, string, hay, muscle fibres, fingernails, longbow, and a bearskin cap.

• Preservation and age estimation

  • Miraculously discovered largely intact.

  • Must have been covered in snow fairly shortly after death.

  • 6 days after discovery an archaeologist claimed it was likely to be at least $4{,}000$ years old.

  • No other human body had been discovered so well preserved.

• Biological analysis and dating

  • Skeletal analysis indicated the man was about $45$ years old.

  • Shot in the shoulder with an arrow that punctured a lung and severed an artery.

  • Carbon dating suggested Ötzi lived between $3350$ and $3100 \text{ BC}$, i.e. roughly $5{,}000$ years ago.

• Items confirming Copper Age context

  • Items found with Ötzi include: bear skin cap, goatskin leggings, copper axe, hide quiver and arrows, flint dagger, grass and deerskin shoes.

• DNA and hoax theories

  • Initially some people thought it was a hoax.

  • Research into mtDNA and Y-chromosome DNA helped to dispel hoax theories.

  • The body was so well preserved that nuclear DNA could be examined as well.

• Genetic and physical profile

  • mtDNA haplogroup: K – common in Northern Italy.

  • Y-chromosome haplogroup: G2a2b – rare today; living relatives in Austria.

  • Physical/phenotypic traits reported: brown eyes; blood group $0$; lactose intolerant; Lyme disease; whipworm; tooth decay; missing ribs.

  • Most likely died in early summer.

The Titanic

• Ship details

  • Built in Belfast in the early 1900s.

  • Length: $269\,\text{m}$; width: $28.2\,\text{m}$.

  • Nicknamed the "Unsinkable".

  • Some extraneous characters appear in the transcript (not part of core content).

• Voyage start and sinking event

  • Set off from Southampton on the $10^{\text{th}}$ of April, $1912$.

  • On board: $2{,}224$ passengers and crew.

  • Hit an iceberg just before midnight on the $14^{\text{th}}$ of April and began sinking.

• Lifeboat shortfall and evacuation order

  • Not enough lifeboats for all on board: $1{,}178$ lifeboat capacity is noted in the transcript.

  • First-class passengers, women and children evacuated first.

  • Many lifeboats released only half full.

  • More than $1{,}500$ people died.

• Survival patterns in the cold water

  • Some lifeboats turned back to look for survivors.

  • Many bodies in the water appeared to be alive due to life jackets and water movement.

  • Others went down with the ship.

  • Only $786$ people survived.

• Handling of the bodies

  • Rescue crews discovered chaos upon reaching the disaster.

  • Bodies were initially placed in coffins or hessian sacks.

  • Eventually bodies were stacked on deck; some embalmed; many buried at sea after identifications.

• Identification efforts and burial

  • Public viewings held to try to identify the bodies.

  • Most poorly preserved.

  • Most bodies buried in Halifax, Canada; $44$ remained unidentified in this cemetery.

  • A project began in the early 2000s to identify these last victims through DNA.

• DNA retrieval challenges

  • Attempts were made to obtain DNA samples from several gravesites.

  • Water damage had destroyed most genetic material.

  • The “Unknown” baby was somewhat protected.

  • A small piece of bone and 3 teeth were recovered.

• Initial identification attempt

  • Passenger lists provided a starting point.

  • Narrowed down to one of 3 unknown children.

  • DNA collected from living maternal relatives.

  • mtDNA was matched to Eino Panula from Finland.

• DNA inconsistencies and resolution

  • However, the mtDNA also matched one of the children that had been ruled out due to the age of the teeth.

  • Shoes had been used as contradictory evidence.

  • More advanced mtDNA tests were performed.

  • The American Armed Forces Identification Lab got involved.

  • Conclusion: the baby was Sidney Leslie Goodwin.

The Romanovs

• Historical background

  • The Romanov family ruled Russia for roughly 300 years.

  • Nicholas II came to power in 1894 and abdicated in 1917.

  • In 1918 the last Romanovs were murdered in the night as part of the Bolshevik Revolution.

  • The location of the bodies remained undiscovered for decades.

• Grave discovery and missing members

  • In 1991 scientists uncovered a disorganized grave.

  • Found were 9 adult skeletons, but there should have been 11.

  • Two children’s skeletons were missing.

  • Question: who was in this gravesite then, and was it actually the Romanovs?

• Chromosome 8 analysis and haplotypes

  • Skeletons were largely intact.

  • Analysis of a small section of chromosome 8 was possible.

  • Haplotypes assigned and family links established using long haplotype data:

  • 15 16 8 8 5 3 13 12 36 32 15 19 7 10 7 7 12 12 11 32 15 19 8 10 5 7 13 12 32 11 16 15 8 10 3 7 13 12 36 32 17 21 18 8 19 7 20 13 32 33 15 16 5 8 6 7 12 15 31 36 18 18 5 9 6 6 13 14 32 32 15 18 5 5 16 7 11 15 32 32

  • Unmatched haplotypes: 15 19 8 10 5 7 13 12 32 11

  • This data helped establish familial connections, though not all relationships were initially clear.

• Mitochondrial DNA and STRs

  • Mitochondrial DNA (mtDNA) was examined.

  • 4 samples shared the same mtDNA sequence.

  • The same 4 samples were also determined to share the same STR (short tandem repeat) profile.

  • The team knew they were a family, but which specific family remained unresolved at this point.

• Royal mtDNA connections

  • A figure shows that Prince Philip shares the same mtDNA, illustrating a matrilineal connection to the same mtDNA sequence.

  • Broader lineage context is given, including Queen Victoria, Prince Albert, Alice, Ludwig of Hesse, Ella, Irene, Henry of Prussia, and others, with connections to the modern royals.

  • Key individuals listed include Prince Philip of England (Duke of Edinburgh, b. 1921) and various Romanovs (e.g., Nicholas II and his daughters Tatiana, Maria, Anastasia, Olga, etc.).

• Tsar and living relatives

  • Discussion of whether the Tsar’s mtDNA could be traced to living relatives.

  • Note: The Tsar’s mtDNA is not passed on to his children, but he has a living maternal relative – the Duke of Fyfe.

• mtDNA sequences and maternal haplotypes

  • Prince Philip and James of Fyfe had mtDNA sequences that differed from the rCRS (revised Cambridge Reference Sequence).

  • Tsar’s maternal haplotype: $16126C, 16169T, 16249T, 16269T, 73G, 263G, 315C$

  • Tsarina’s maternal haplotype: $16111T, 16357C, 263G, 315C$

  • Distinction between female samples and male samples is noted in the transcript.

• Inbreeding considerations and alternative origins

  • The question of whether the bones could belong to another family is addressed.

  • Royal inbreeding makes it extremely unlikely that these bones belong to another family.

  • The Romanov family was buried in a family monument, reinforcing the likelihood of correct attribution.

• The missing children and their identification

  • In 2007 bones were found by amateur archaeologists near the other burial site.

  • mtDNA and chromosome 8 STR analysis confirmed they were indeed the missing Romanov children.

Key connections and implications

• Preservation and DNA analysis in Ötzi demonstrate how ancient remains can yield both mitochondrial and nuclear DNA, enabling insights into ancestry, health, diet, and physical traits, as well as dating and context for Copper Age populations.

• The Titanic case highlights practical challenges in disaster response, identification of victims after mass casualties, and the role of DNA technologies (mtDNA) in resolving identifications when other records are incomplete, along with ethical considerations around burial and memorials.

• The Romanovs case showcases how modern genetics, including mtDNA and chromosome 8 STRs, can resolve questions of kinship and lineage across centuries, the importance of matrilineal inheritance, and how inbreeding reduces the likelihood of misattribution while still leaving open questions about extended family connections.

• Across all three case studies, genetic evidence is integrated with historical records (passenger lists, burial sites, royal genealogies) to build a coherent narrative about identity, lineage, and historical context.

• Ethical and practical implications include handling of human remains, the use of DNA for identification, and how discoveries influence collective memory and historical interpretation.

Key terms to remember

• Hablogroups: mtDNA haplogroup K; Y-chromosome haplogroup G2a2b.

• mtDNA and STRs: mitochondrial DNA and short tandem repeats used in familial matching.

• rCRS: revised Cambridge Reference Sequence (mtDNA standard).

• Chromosome 8 haplotypes: used to establish family links in the Romanovs.

• Burial and identification ethics: balancing scientific interest with respect for the deceased and affected communities.
