So suggests new research that tracked changes in two genes thought to help regulate brain growth, changes that appeared well after the rise of modern humans , years ago. That the defining feature of humans — our large brains — continued to evolve as recently as 5, years ago, and may be doing so today, promises to surprise the average person, if not biologists. Lahn and colleagues examined two genes, named microcephalin and ASPM, that are connected to brain size. If those genes don’t work, babies are born with severely small brains, called microcephaly. Using DNA samples from ethnically diverse populations, they identified a collection of variations in each gene that occurred with unusually high frequency. In fact, the variations were so common they couldn’t be accidental mutations but instead were probably due to natural selection, where genetic changes that are favorable to a species quickly gain a foothold and begin to spread, the researchers report. Lahn offers an analogy: Medieval monks would copy manuscripts and each copy would inevitably contain errors — accidental mutations. Years later, a ruler declares one of those copies the definitive manuscript, and a rush is on to make many copies of that version — so whatever changes from the original are in this presumed important copy become widely disseminated. Scientists attempt to date genetic changes by tracing back to such spread, using a statistical model that assumes genes have a certain mutation rate over time.
A CST member smiles with an Afghan girl in Kandahar province in , during a visit to deliver school supplies, food and clothes. Eventually they reached a tiny village where the men of 75th Ranger Regiment were at work seeking the weapons and insurgent who was the target of their mission. They were on nighttime combat operations, learning what Afghan women knew about what was happening in their communities and keeping them separated from the work Rangers were charged with doing nearby.
The early hominids walked upright and possessed a more sophisticated culture than had previously been assumed. One of the skeletons, excavated in , is known simply as Shanidar 3.
Although it is true that recent U. This is mainly because the underlying problems with the Iraqi security forces are political. The regime in Baghdad has little interest in building the neutral, nonsectarian professional army that the United States has long wanted to create, and this fundamental clash of objectives, common in instances of security forces assistance , has produced serious obstacles to the Iraqi combat effectiveness needed to push back the Islamic State.
Furthermore, the United States has relatively little leverage to pressure Baghdad into conforming to its wishes, in part because it lacks a credible exit option and in part because Iraq can turn to Iran as an alternative patron. Currently, the United States has a total military presence in Iraq of about 3, personnel. Of these, work as trainers and serve as advisers. Yet this effort has produced disappointing results.
First, only a fraction of the Iraqi army — about 13, soldiers — has received any training. Privately, some officials have noted that even when recruits are provided, they are more likely to be support personnel from rear echelons, such as cooks, than fully formed combat units. The recent attempt to retake Ramadi has stalled badly. Ramadi is a Sunni-dominated town long ignored by the Shiite regime in Baghdad, which allowed it to fall to Islamic State forces after local Sunni fighters endured a brutal siege earlier this year.
Some Iraqi officers now fighting and failing to retake Ramadi have pointed the finger at a supposed lack of U. But the real problems stem from a lack of basic tactical skills and, most importantly, an inability to aggregate those skills into the performance of complex operations involving both initiative by individual units and coordination across units.
It also suggests that these skills are particularly unlikely to develop in regimes that are more concerned with maintaining power , especially in the face of political threats from their own military organizations, than combating conventionally powerful adversaries.
Family threats, militia murders, persecution, and fear: Shortly after that, I had to escape to save my life. The report was compiled by advocacy group IraQueer and a partner group that wishes to remain anonymous for safety reasons. It was founded in This number might sound small when compared to other studies in countries like the U. But for a country like Iraq, where any kind of public participation can lead to facing violence and potentially death, this number is positively surprising.

Showbak A lonely reminder of former Crusader glory is Showbak Castle, less than an hour north of Petra. Once called “Mont Real,” Showbak dates from the same turbulent period as Karak. It is perched on the side of a mountain, with a grand sweep of fruit trees below. The castle’s exterior is impressive, with a foreboding gate and encircling triple wall. Despite the precautions of its builder, the fortress fell to Saladin only 75 years after it was raised.
Inscriptions by his proud successors appear on the castle wall. Perched on a splendid hilltop overlooking the Jordan Valley and the Sea of Galilee, Umm Qays boasts impressive ancient remains, such as the stunning black basalt theatre, the basilica and adjacent courtyard strewn with nicely carved black sarcophagi, the colonnaded main street and a side street lined with shops, an underground mausoleum, two baths, a nymphaeum, a city gate and the faint outlines of what was a massive hippodrome.
Pella Tabqit Fahl Pella is exceptionally rich in antiquities, some of which are exceedingly old. Besides the excavated ruins from the Graeco-Roman period, Pella offers visitors the opportunity to see the remains of Chalcolithic settlement from the 4th millennium BC, evidence of Bronze and Iron Age walled cities, Byzantine churches, early Islamic residential quarters and a small medieval mosque. Umm Al-Jimal The eastern most of the major northern cities, Umm Al-Jimal is located at the edge of the eastern basalt desert plain, along a secondary road that was close to the junction of several ancient trade routes that linked central Jordan with Syria and Iraq.
Among the most interesting structures to visit are the tall barracks with their little chapel, several large churches, numerous open and roofed water cisterns, the outlines of a Roman fort, and the remains of several town gates. Another feature at Umm Ar-Rasas walled settlement is a 15m Byzantine tower used by early Christian monks seeking solitude. The Kings’ Highway The Kings’ Highway winds its way through the different ecological zones of the country, including forested highlands, open farmland plateaus, deep ravines, the edge of the Eastern Desert, and the warm tropical Gulf of Aqaba.

Victory stele of Naram-Sin of Akkad. Bronze Age In the 26th century BC, Eannatum of Lagash created what was perhaps the first empire in history, though this was short-lived. Later, Lugal-Zage-Si , the priest-king of Umma , overthrew the primacy of the Lagash dynasty in the area, then conquered Uruk , making it his capital, and claimed an empire extending from the Persian Gulf to the Mediterranean.
From the 29th century BC, Akkadian Semitic names began to appear on king lists and administrative documents of various city states. It remains unknown as to the origin of Akkad, where it was precisely situated and how it rose to prominence.
Japanese Culture Japan has a fascinating and multifaceted culture; on the one hand it is steeped in the deepest of traditions dating back thousands of years; on the other it is a society in a continual state of rapid flux, with continually shifting fads and fashions and technological development that constantly pushes back the boundaries of the.
These people founded the first dynasty of Babylon 19th—16th centuries , whose most important king was Hammurabi. In the 17th century new ethnic groups appeared in both Babylonia and Syria-Palestine: Kassites from the Zagros Mountains,… Foundation of the city At some time in the 4th millennium bce, the city was founded by settlers thought to have been from northern Mesopotamia, farmers still in the Chalcolithic phase of culture.
There is evidence that their occupation was ended by a flood, formerly thought to be the one described in Genesis. Ur in the early dynastic period, 29th—24th century bce In the next Early Dynastic period Ur became the capital of the whole of southern Mesopotamia under the Sumerian kings of the 1st dynasty of Ur 25th century bce. Excavation of a vast cemetery from the period preceding that dynasty 26th century produced royal tombs containing almost incredible treasures in gold, silver, bronze, and semiprecious stones, showing not only the wealth of the people of Ur but also their highly developed civilization and art.
Not the least remarkable discovery was that of the custom whereby kings were buried along with a whole retinue of their court officials, servants, and women, privileged to continue their service in the next world.

March 28, Courtesy of Goran M. Amin Construction workers accidentally discovered a vaulted tomb dating back to the time of the Assyrian Empire in Erbil, the capital of Iraqi Kurdistan. Ten skeletons were also found at the site. Inside the tomb, which was constructed with baked bricks, archaeologists discovered three ceramic sarcophagi holding two skeletons.
Dating is a stage of romantic relationships in humans whereby two people meet socially with the aim of each assessing the other’s suitability as a prospective partner in an intimate relationship or is a form of courtship, consisting of social activities done by the couple, either alone or with others. The protocols and practices of dating, and the terms used to describe it, vary.
Ethnicity, Culture and Religion Christianity entered Mesopotamia from the beginning of the Christian era, and many natives of that land became Christians. Christians remained what they were, i. Therefore, present-day Chaldeans and Assyrians are precisely that: To be accurate from the start, I must add this clarification: These remarks indicate two ingredients in the formation of early Mesopotamian Christianity, that have merged gradually into the general Christian population.
But we can state quite accurately that the hard and large core of that early Christianity was formed from the common population of contemporary Mesopotamia. Therefore, if we pose again the question: Who are the actual Christians of Iraq, i.
South of this lies Babylonia , named after the city of Babylon. However, in the broader sense, the name Mesopotamia has come to be used for the area bounded on the northeast by the Zagros Mountains and on the southwest by the edge of the Arabian Plateau and stretching from the Persian Gulf in the southeast to the spurs of the Anti-Taurus Mountains in the northwest. As a result of the slow flow of the water, there are heavy deposits of silt, and the riverbeds are raised.
Consequently, the rivers often overflow their banks and may even change their course when they are not protected by high dikes. In recent times they have been regulated above Baghdad by the use of escape channels with overflow reservoirs.
History of Mesopotamia, history of the region in southwestern Asia where the world’s earliest civilization developed. The name comes from a Greek word meaning “between rivers,” referring to the land between the Tigris and Euphrates rivers, but the region can be broadly defined to include the area that is now eastern Syria, southeastern Turkey, and most of Iraq.
Iraq is the classic case. I was opposed to the invasion of that country, not because I had any love for Saddam but because I believed that the alternative would be worse. I was concerned that our invasion would destroy the stability of the Gulf which had, since the fall of the Shah in , depended on a tripod comprising Iran, Iraq and Saudi Arabia the latter supported by the West.
That is exactly what happened and we now find that the Iranians are in a position to dominate the Gulf region. Internally, the outcome was even worse. The army was disbanded although some would say it disbanded itself.
