Digging Beneath Britain’s Houses of Parliament

The Palace of Westminster in London houses Britain’s Parliament. While digging beneath this palace, archaeologists have discovered several artifacts, including a 19^th-century beer jug, a fragment of a 2,000-year-old Roman altar, and 6,000-year-old prehistoric flint flakes.

Excavations were commissioned by the Houses of Parliament Restoration and Renewal Program. The digs are part of an ongoing archaeology project to illuminate Westminster’s history and inform restoration work.

Westminster has been a central part of Britain’s national story for at least a thousand years. It has been the location of momentous events in the U.K.’s history. While planning for restoration and renewal, scientists must also protect and learn from the history below the building.

60 prehistoric flint fragments (which date to about 4300 BCE) are evidence of toolmaking in the late Mesolithic or early Neolithic periods. Tools were made from flint by chipping the stone until it had a sharp edge. They were discovered in sand deposits that once formed part of Thorney Island, where prehistoric inhabitants fished, hunted, and gathered food. Finding prehistoric remains in central London is rare.

Researchers also discovered remains of Lesser Hall, also known as the White Hall. As a medieval two-story building built in 1167, it originally was a royal dining area. Later, it accommodated the Court of Chancery, the Court of Requests, the House of Commons, and the House of Lords during certain time periods. This was an unexpected discovery found below the present-day courtyard and car park.

When Lesser Hall housed the House of Lords in 1834, a fire started in the basement furnace room and became the Great Fire of 1834. These excavations showed the hall’s stone walls survived the fire. The building was reroofed and used until 1851, when it was demolished. The discovery of Lesser Hall provides insights into the layout of historic structures. The remains of Lesser Hall and other pre-1834 structures were documented (and some recreated in 3D models) before being reburied.

The Roman altar fragment was likely repurposed in another structure built later. Other artifacts included 800-year-old shoe soles, straps, a leather boot, and a lead badge shaped like a flowering heart from the 14^th or 15^th century.

Several artifacts from the 19^th century included fragments of clay tobacco pipes, which were probably smoked by the stonemasons working after the 1834 fire. Also found was a five-pint beer jug bearing the words “Ship and Turtle Tavern”. It also said “Geo Painter”, which likely referred to George Painter, the owner of the tavern.

I’ve been to London. I found it to be a very busy place. And all these artifacts show that it has been a busy place for a very long time.

Ancient Tools Contradict the Timeline of Civilization

When studying the proliferation of humanity across the globe, researchers have been stumped by how the islands of Southeast Asia (ISEA) became well-inhabited so long ago.

It was thought that technological seafaring advancements to make this possible were unlikely during the Paleolithic era. But research now shows that the ancient people of the Philippines and ISEA may have mastered seafaring well before anyone else.

The evidence is stone tools excavated in the Philippines, Indonesia, and Timor-Leste, which indicates that 40,000 years ago, ancient seafarers had technological sophistication that rivals much later civilizations.

Proving seafaring history is tricky because wood and fiber that would have been used to construct Paleolithic seacraft rarely survive in the archaeological record. These stone tools show traces of plant processing to extract fibers used for making ropes, nets, and boatbuilding bindings. When you also discover fishing hooks, gorges, net weights, and the remains of deep-ocean fish (tuna and sharks), it is plain these archeological sites are of a robust seafaring culture.

The remains of large predatory fish indicate advanced seafaring capabilities as well as knowledge of those fish species’ migration routes. The fish and tool remains show a need for strong and well-crafted cordage for ropes and fishing lines.

It seems that ancient seafarers constructed boats from organic materials and held them together with ropes. The rope technology was then adapted for fishing.

Up until now, the prevailing theory is that prehistoric migrations were passive sea drifters on bamboo rafts. These researchers posit that such migrations were made by highly skilled navigators who had the knowledge and technology to travel over deep water to remote locations.

This advanced maritime technology highlights the ingenuity of early ISEA peoples. Their boat-building knowledge probably made the region a center for technological innovations thousands of years ago, laying the foundation for maritime traditions that still thrive there today.

New Timeline of Life on Earth

Evidence of ancient life on Earth is tough to find. But some scientists think they’ve found some of the oldest. Previously, it was estimated that the oldest biomolecules known by man were about 2.5 billion years old. However, the oldest biosignatures are actually 3.3 billion years old.

The authors of a new study claim to have deepened our understanding of Earth’s earliest biosphere and, at the same time, will provide new avenues for potentially finding past life on Mars and other planets.

The team studied the world’s oldest rocks. High-resolution chemical analysis broke down organic and inorganic materials from the rocks, producing molecular fragments. An artificial intelligence system was used to recognize the chemical fingerprints left behind by life. The system learned how to do this by analyzing 406 samples of plants, animals, fossils, and meteorites. The AI can distinguish between biological and non-biological material with over 90% accuracy.

The biggest splash was the detection of photosynthesis in 2.5-billion-years-old rocks. It seems that ancient life leaves more than fossils. It also leaves chemical echoes, which the AI can now reliably interpret. Computers have been trained to recognize any molecular trace left by living organisms, even after the biomolecules were gone.

Earth’s earliest life hasn’t left many traces behind, since ancient cells have been swallowed by Earth’s crust. This has pretty much obliterated clues about the origins of life. But the researchers hope ancient rocks can reveal glimpses of that history.

Most organic molecules from the past have been altered by geological processes but are still useful to study. And this process isn’t restricted to Earth-formed rocks, either. It could help guide the search for life on other planets.

Why This Ancient Civilization Vanished

The ancient Indus River Valley civilization had gridded streets, multistory homes, flush toilets, and bustling shops. It traded gold, precious stones, and bronze carts with other areas along the region’s waterways. Some people carved human figurines and others made toys of clay. Crops included wheat, barley, and cotton. Tools were made to bring water from nearby rivers for crops.

The valley is largely located in Pakistan and northwest India. It hosted one of the most advanced societies at the time, rivaling Mesopotamia and ancient Egypt. And then it disappeared.

Scientists have been looking at the environmental conditions in an attempt to explain the downfall of Harappa, one of the valley’s largest cities. Using paleoclimate data and computer models, they re-created the climate during the civilization’s existence, which was between 3000 and 1000 BC. During that time, four intense droughts dried up waterways and soils. This probably caused the Harappan residents to relocate frequently.

Harappa’s decline was partially caused by repeated, long, and intensifying rivers droughts that lasted centuries. It is thought that if there is less food and a weak government, such droughts can push a civilization over the brink. Despite the persistent droughts, this civilization lasted a long time.

Over 2,000 years, Harappan settlements became more concentrated closer to water.

Scientists determined that vigorous monsoons across the region created much wetter conditions than today. That was between 3000 and 2475 BC. But then drier conditions and increased temperatures came in. And droughts.

There were four droughts—each lasting more than 85 years—between 2425 and 1400 BC. The third drought was the worst and it peaked around 1733 BC. It lasted for 164 years and affected most of the region.

The rainfall changes meant lakes and shallow waterbodies shrank, river flow decreased, and the soil dried up. Lower rivers meant that trade boats and barges could only move at certain times. Agriculture also became tougher in areas away from waterways.

This pushed people to move, which may have contributed to the society’s decline.
