What was happening 3600 years ago

Hunter-gatherer nomads. Isotopic analysis suggests most people were non-locals, hailing not from a unified homeland but an international influx.

Other archaeological evidence supports this idea. Researchers have struggled to find signs of a battle in this region, despite extensive burial sites, and during this time, there's more documentation of men with Egyptian names marrying women with non-Egyptian names than the other way around. This matters because most invasions in history have been waged by men.

Yet the new analysis suggests before the Hyksos uprising, there were far more non-local females immigrating to this region than non-local males. Egyptologist Orly Goldwasser, who was not involved in the study, told Science Magazine he suspects most immigrants travelled to Egypt during this time with peaceful intentions. While ancient historians described them as "invaders of an obscure race", some archaeologists suspect that's actually 'fake news' or ancient propaganda.

Instead, they argue the Hyksos probably rose to power in a slow and peaceful way, bringing technology like the horse and chariot along with them. Clothing and wood immediately burst into flames. Swords, spears, mudbricks and pottery began to melt. Almost immediately, the entire city was on fire.

Some seconds later, a massive shockwave smashed into the city. The deadly winds ripped through the city, demolishing every building. They sheared off the top 12 metres of the 4-story palace and blew the jumbled debris into the next valley.

None of the 8, people or any animals within the city survived — their bodies were torn apart and their bones blasted into small fragments. About a minute later, 22 km to the west of Tall el-Hammam, winds from the blast hit the biblical city of Jericho. It all sounds like the climax of an edge-of-your-seat Hollywood disaster movie. How do we know that all of this actually happened near the Dead Sea in Jordan millennia ago? Getting answers required nearly 15 years of painstaking excavations by hundreds of people.

It also involved detailed analyses of excavated material by more than two dozen scientists in 10 states in the United States, as well as Canada and the Czech Republic. When our group finally published the evidence recently in the journal Scientific Reports, the 21 co-authors included archaeologists, geologists, geochemists, geomorphologists, mineralogists, paleobotanists, sedimentologists, cosmic-impact experts and medical doctors.

Here is how we built up this picture of devastation in the past. Years ago, when archaeologists looked out over excavations of the ruined city, they could see a dark, roughly 1. It was obvious that an intense firestorm had destroyed this city long ago. This dark band came to be called the destruction layer. No one was exactly sure what had happened, but that layer was not caused by a volcano, earthquake or warfare.

None of them is capable of melting metal, mudbricks and pottery.
