French Soldiers Weighed Down by Armour at Agincourt in 1415


France may have lost the battle of Agincourt because their soldiers' armour was so heavy it left them breathless, researchers have claimed.

Wearing a full suit of armour doubled the amount of energy used in battle, according to a new study in which volunteers dressed as 15th century knights were made to run on a treadmill.

The exertion of carrying the steel plate armour, which weighed between 30 and 50kg, (66-110lb), would have placed additional weight on each limb and hampered the wearer's breathing, making them weaker in a fight.

This meant that heavily-armoured French soldiers stood little chance when advancing across boggy ground towards more lightly attired British archers at Agincourt in 1415, experts said.

"Lady of Introd:" Iceman's "Girlfriend" Found

Italian workers building an addition to a kindergarten have unearthed a well preserved female skeleton who might be relatively contemporaneous with Ötzi, the Iceman mummy discovered 20 years ago in a melting glacier in South Tyrol.

The "Lady of Introd" or "Ötzi's girlfriend," as the skeleton was nicknamed in Italy, was found in the tiny Alpine village of Introd, in the Val d'Aosta, famous to be the preferred vacationing spot for both Pope John II and his successor Benedict XVI.

According to archaeologists and anthropologists, the woman has been lying on her right side, with her head facing west, for about 5,000 years.

The dating to the third millennium B.C. was based on the skeleton's burial position and stratigraphy, said Vittorio Anglesio, mayor of Introd.

"She appears to have been buried without any grave goods. However, we are now going to extend the dig to better investigate the area," Anglesio told Discovery News.

Ancient Footprints Show Human-Like Walking Began Nearly 4 Million Years Ago

Scientists at the University of Liverpool have found that ancient footprints in Laetoli, Tanzania, show that human-like features of the feet and gait existed almost two million years earlier than previously thought.

Many earlier studies have suggested that the characteristics of the human foot, such as the ability to push off the ground with the big toe, and a fully upright bipedal gait, emerged in early Homo, approximately 1.9 million years-ago.

Liverpool researchers, however, in collaboration with scientists at the University of Manchester and Bournemouth University, have now shown that footprints of a human ancestor dating back 3.7 million years ago, show features of the foot with more similarities to the gait of modern humans than with the type of bipedal walking used by chimpanzees, orang-utans and gorillas.

The footprint site of Laetoli contains the earliest known trail made by human ancestors and includes 11 individual prints in good condition. Previous studies have been primarily based on single prints and have therefore been liable to misinterpreting artificial features, such as erosion and other environmental factors, as reflecting genuine features of the footprint. This has resulted in many years of debate over the exact characteristics of gait in early human ancestors.

Mysterious Fossils Provide New Clues to Insect Evolution

German scientists at the Stuttgart Natural History Museum were leading in the discovery of a new insect order from the Lower Cretaceous of South America. The spectacular fossils were named Coxoplectoptera by their discoverers and their findings were published in a special issue on Cretaceous Insects in the scientific journal Insect Systematics & Evolution.

The work group led by Dr. Arnold H. Staniczek and Dr. Günter Bechly, both experts on basal insects, determined that these fossils represent extinct relatives of modern mayflies. Coxoplectoptera however significantly differ from both mayflies and all other known insects in anatomy and mode of life. Due to the discovery of adult winged specimens and excellently preserved larvae, the scientists were able to clarify the phylogenetic position of these animals and presented a new hypothesis regarding the relationships of basal winged insects.

Canada: Manitoba Dig Unearths 80-Million-Year old "T-Rex of the Sea" Skeletons, Squid

Manitoba paleontologists have unearthed the bones of a prehistoric sea creature some 80 million years old.

Scientists from the Canadian Fossil museum in Morden have dug up two Mosasaurs -- a huge reptile known as the "T-Rex of the sea."

The dig site also uncovered a prehistoric squid and bird fossils, giving scientists new insight into what Western Canada looked like 80 million years ago.

The museum is already home to a Mosasaur called "Bruce", but curator Anita Janzic says the new find is significant.

She says the discovery of some shore bird fossils seems to contradict the idea that much of the Prairies were under water at the time.

She says they expect to keep working at the southwestern Manitoba dig site for several years and will write up their findings for academic journals.

Mesolithic "rest stop" found at UK supermarket site

An early prehistoric hearth has been discovered on the planned construction site for a branch of major British supermarket chain Sainsbury's

The charcoal remains, excavated from the site in Nairn, a town in the Scottish Highlands, date back to the Mesolithic period (10,000 to 4000 BC). They are believed to have been a temporary travelling stop rather than a settlement, due to the absence of any further Mesolithic findings at the site.

"An extremely large quantity of wood charcoal fragments was recovered from the hearth. The size of the fragments suggests either deliberate deposition or in-situ burning," said Headland Archaeology, who carried out the excavation, in a report.

Archaeologists used carbon-dating of the charcoal to determine the age of the hearth. However, dating a site from this particular substance is problematic, due the potential time lag between the felling of the tree and the burning of the material, the report said.

UK: Urge to binge on fatty food 'dates back to the Ice Age'

Our frozen ancestors of the Ice Age needed plenty of fat in their diets to keep warm - and it seems we might still be carrying their genetic torch.

For British scientists have discovered a DNA switch in the brain that they believe makes Europeans far more likely to binge on fatty food than those living in the East.

The researchers from Aberdeen University made their discovery after comparing the DNA of people with the genetic code of birds and mice.

Comment: It seems like our ancestors knew a thing or two about proper nourishment. And we are not talking about a mere survival and preservation of body's heat during harsh periods. It appears that fat is the preferred fuel of human metabolism and has been for most of human evolution. It not only decreases inflammation and significantly increases energy levels, but improved and healthier brain activity facilitates creativity and human evolution.

Read the following articles to understand how currently promoted low-fat diets lead to slow degradation and danger, especially prior to the possible onset of the next Ice Age.

Submerged sites of ancient communities could be hidden in the seas around the Western Isles, according to experts.

Dr Jonathan Benjamin and Dr Andrew Bicket believe the islands' long and sheltered lochs have protected 9,000-year-old Mesolithic relics.

Rising sea levels may have covered up to 6.2 miles (10km) of land on the west coast of the Outer Hebrides.

The archaeologists are to give a presentation in Comhairle nan Eilean Siar's council chambers on Monday.

During the Mesolithic period, also known as the Middle Stone Age, Britain was transformed from a peninsula to an island.

Ethiopian lake reveals history of African droughts

A new survey of Lake Tana in Ethiopia - the source of the Blue Nile - suggests that drought may have contributed to the demise of the Egyptian Old Kingdom, around 4200 years ago.

A team led by the University of Aberystwyth used seismic surveys and sediment cores to work out how the lake's water levels has varied over the past 17,000 years and linked this to evidence for global climate change.

Understanding how and why rainfall patterns change is particularly important for sub-Saharan Africa, where prolonged droughts have such serious social and economic consequences.

The climate here is dominated by the African-Asian monsoon and the movements of the Intertropical Convergence Zone (ITCZ). This is an area of erratic weather patterns, where winds from the northern and southern hemispheres meet close to the equator: sailors know it as the Doldrums.

UK: "Fantastic results" at Roman Dig in Maryport

The excavation of a Roman site at Maryport, in Cumbria, has produced "fascinating results", experts say.

The project at the remains of a Roman fort at Camp Farm, which started last year, is due to be completed on 22 July.

The team said it had found many features not recorded by a previous excavation in 1870.

Among them are fragments of altars, traces of timber buildings, pottery and coins.

A team of 28 volunteers has worked alongside the archaeologists on the project, which was commissioned by the Senhouse Museum Trust.

It was led by Professor Ian Haynes, from Newcastle University, and field archaeologist Tony Wilmott.
