Japan study : Pigeons have Eye for Paintings

pigeons_01-300x198Pigeons may sometimes appear to randomly target city sculptures with their droppings, but according to a new Japanese study they also have the potential to become discerning art critics.

Researchers at Tokyo’s Keio University say they have found that the birds have “advanced perceptive abilities” and can distinguish between “good” and “bad” paintings, recognising beauty the way humans do.

The team — which previously published research saying that pigeons can tell a Monet from a Picasso — was seeking to find out whether the animals may also be able to prefer one to the other.

For their experiment, the scientists took paintings by elementary school children and selected those that were commonly deemed to be “good” and “bad” by teachers and a control group of other adults.

60-mln yr old rabbit-sized elephant ancestor found in Morocco

elephant_evolution_01-300x226Scientists have found the fossil of a 60-million-year-old creature in Morocco, which is the rabbit sized ancestor of the modern day elephant.

Paleontologist Emmanuel Gheerbrant discovered the rabbit-size proto-elephant’s skull fragments in a basin 60 miles (100 kilometers) east of Casablanca, Morocco.

The creature, called Eritherium azzouzorum, bolsters the case that whole new orders of mammals were already around less than 6 million years after global catastrophe ended the age of reptiles some 65.5 million years ago.

Elephant ancestors now join the likes of rodents and early primates as some of the first known mammals to walk the Earth during the Paleocene era, 65.5 to 55 million years ago (prehistoric time line), according to Gheerbrant.

Israeli archaeologists discover ancient quarry

Israeli archaeologists have uncovered an ancient quarry where they believe King Herod extracted stones for the construction of the Jewish Temple 2,000 years ago, the Israel Antiquities Authority said Monday. The archaeologists believe the 1,000-square-foot (100-square-meter) quarry was part of a much larger network of quarries used by Herod in the city.

The biggest stones extracted from the quarry would have measured three yards (meters) long, two yards (meters) across, and two yards (meters) high.

The archaeologists said the size of the stones indicates they could have been used in the construction of the Temple compound, including the Western Wall, a retaining wall that remains intact and is a Jewish shrine.

“The dimensions of the stones that were produced in the quarry that was revealed are suitable for the Temple walls,” said Ofer Sion, the dig’s director.

Arkaim, a mystery of civilization

arkaim_01The site is generally dated on the 17th century BC. Earlier dates, up to the 20th century BC, have been proposed. It was a settlement of the Sintashta-Petrovka culture. Arkaim is an archaeological site situated in the Southern Urals steppe, 8.2 km north-to-northwest of Amurskiy, and 2.3 km south-to-southeast of Alexandronvskiy, two villages in the Chelyabinsk Oblast, Russia, just to the north from the Kazakhstani border. The site was discovered in 1987 by a team of Chelyabinsk scientists who were preparing the area to be flooded in order to create a reservoir, and examined in rescue excavations led by Gennadii Zdanovich. At first their findings were ignored by Soviet authorities, who planned to flood the site as they had flooded Sarkel earlier, but the attention attracted by news of the discovery forced the Soviet government to revoke its plans for flooding the area. Although the settlement was burned and abandoned, much detail is preserved. Arkaim is similar in form but much better preserved than neighbouring Sintashta, where the earliest chariot was unearthed. The site was protected by two circular walls. There was a central square, surrounded by two circles of dwellings separated by a street. The settlement covered ca. 20,000 m². The diameter of the enclosing wall was 160 m. It was built from earth packed into timber frames, and reinforced with unburned clay brick, with a thickness of 4-5 m. and a height of 5.5 m. The settlement was surrounded with a 2 m-deep moat.
