Assumptions about origins of life challenged

Assumptions about origins of life challenged | Aux origines | Scoop.it
Before there was life on Earth, there were molecules. A primordial soup. At some point a few specialized molecules began replicating. This self-replication, scientists agree, kick-started a biochemical process that would lead to the first organisms.

Stone me! It’s Britain’s newest stone circle

Stone me! It’s Britain’s newest stone circle | Aux origines | Scoop.it

A STONE circle has been restored to its former glory after “going missing” for over 200 years.

The circle was discovered in a meadow at Wilton, near Egremont by landowners Philip and Lyndsey Johnson. And according to Dr Terence Meaden, a research archaeologist from Oxford University, the stones could be over 4,000 years old.

The formation was unearthed when the Johnsons began researching the history of their house.

Stonehenge facts

The article, including the headline, (Stonehenge dig finally unravels the mystery of why it was built, 9 September) failed to distinguish between fact and interpretation, and presented one expert's view as established fact. It also gives the impression that the expert's view has been adopted by English Heritage. This is very confusing for your readers. English Heritage is firmly of the view that Stonehenge was built as a prehistoric temple aligned with the movements of the sun, contrary to what was implied in the article.

Summer Discoveries at Stoneheng

Two ditches belonging to the Stonehenge Avenue buried beneath the modern roadbed of the A344 have been uncovered during works to decommission the road as part of English Heritage's project to transform the setting and visitor experience of Stonehenge.

The two ditches represent either side of The Avenue, a long linear feature to the north-east of Stonehenge linking it with the River Avon. It has long been considered as the formal processional approach to the monument and is aligned with the solstice axis of Stonehenge. But its connection with Stonehenge had been severed by the A344 for centuries as the road cut through the delicate earthwork at an almost perpendicular angle.

The two ditches were found in their expected positions near to the Heel Stone, about 24 metres from the entrance to monument.

Prehistoric Archaeology Blog: Stonehenge was built on solstice axis, dig confirms | Aux origines | Scoop.it

English Heritage says it has discovered a "missing piece in the jigsaw" in our understanding of Stonehenge, England's greatest prehistoric site. Excavations along the ancient processional route to the monument have confirmed the theory that it was built along an ice age landform that happened to be on the solstice axis, according to Professor Mike Parker Pearson, a leading expert on Stonehenge.

An international team that includes Spanish researchers has sequenced the mitochondrial genome (special DNA passed on exclusively by mothers) of bears who lived about 400,000 years ago in Atapuerca, near Burgos in northern Spain. This brings scientists closer to sequencing the entire genome of pre-Neanderthal humans who lived at the same time, and who hold clues about the evolution of our species.
