Humans may have been driven out of Africa 70,000 years ago by a changing climate, according to a new study.While scientists have long suspected the region may have experienced climatic changes in line with the known period of migration, a new study has found evidence to suggest the people may have been escaping a ‘deteriorating’ environment.“The notion that you have a seal of approval just because you’re not a criminal — that you walk into a gun store and you’re ready for game day — is ridiculous,” said David Chipman, a former SWAT team member with the Bureau of Alcohol, Tobacco, Firearms and Explosives.

“I think there’s this fantasy world of gunplay in the movies, but it doesn’t really happen that way.When I heard gunfire [in Iraq], I didn’t immediately pick up my rifle and react.According to the researchers, the new study supports this idea, suggesting climate may have played a large role in the migration out of Africa.‘Our main point is kind of simple,’ Tierney said.‘We think it was dry when people left Africa and went on to other parts of the world, and that the transition from a Green Sahara to dry was a motivating force for people to leave.’Sony SRS-XB40 has a built-in multi-coloured line light, speaker lights and a flashing strobe.It features 24 hours of battery life and claims to be a 'mini-disco on the move'. The team also analyzed ancient leaf wax that had blown into the ocean, helping to determine the rainfall patterns.

And, their investigation revealed a shift toward a much colder, drier climate.‘Our data say the migration comes after a big environmental change,’ Tierney said.‘Perhaps people left because the environment was deteriorating.

“We could have opened ourselves up to be potential targets ourselves, and not knowing where SWAT was, their response time, they wouldn’t know who we were, and if we had our guns ready to shoot, they could think that we were bad guys,” said Parker, Ben Carson infamously criticized those in Oregon who stood by, claiming that he would have attacked the shooter with a group of people.

However, the GOP candidate fails to take into account that a “good guy” would have to overcome their biological instinct for survival.

They also analyzed ancient leaf wax that had blown into the ocean, helping to determine the rainfall patterns.‘There’s always been a question about whether climate change had any influence on when our species left Africa,’ said Jessica Tierney, UA associate professor of geosciences.‘Our data suggest that when most of our species left Africa, it was dry and not wet in northeast Africa.’In the study, led by researchers at the University of Arizona, the team worked with the curators of the Lamont-Doherty Core Repository to find a core sediment from northeast Africa dating back 55,000 to 70,000 years ago, or around the time genetic research indicates people migrated from Africa into Eurasia.

The team analyzed a sample collected off the Horn of Africa in 1965 and discovered it had sediments going back 200,000 years.

There was a big shift to dry and that could have been a motivating force for migration.
