How cats conquered the world

A new study outlines how cats went from pest-controllers to human companions and found that most cats come from one of two major lineages of felines from the Near East and Egypt.

How they did it: Scientists analyzed ancient and modern DNA from the remains of over 200 cats that lived during the past 9,000 years, including Egyptian cat mummies and modern wildcats from Bulgaria and East Africa.

  • Cat's cradle: Cats began living side-by-side with humans about 9,000 years ago when farmers in the Near East seem to have first tamed their wild ancestors.
  • Biggest contributors to today's domestic cat gene pool: A cat lineage that first appeared in the Near East and then spread into Europe beginning around 4400 BC and another of Egyptian cats that moved throughout the Mediterranean along trade routes and paths of war (potentially to help control rodents on ships) during the first millennium BC. They then mated with local cats - tame or wild.
  • It's not all appearance: The genetic variant responsible for the distinct markings of tabby cats weren't found at a high frequency until after the Middle Ages, suggesting cats were until relatively recently selected for their behavior not their looks.

President Trump and Russian President Vladimir Putin spoke on Monday about Trump's plans to expand September's G7 meeting in Washington to include Russia, according to the Russian government's readout of the call.

The big picture: The phone call between the two leaders, which the Kremlin says was initiated by Trump, comes amid six consecutive days of mass unrest in the U.S. over police brutality and racial inequality. The White House confirmed the call took place and said a readout was forthcoming.

Facebook employees stage "virtual walkout"

"Dozens" of Facebook employees staged a "virtual walkout" Monday over the company's decision not to take action against President Trump's provocative messages in the face of nationwide protests against police violence, the New York Times reports.

Why it matters: While Twitter added fact-check labels and hid the president's most inflammatory tweet — "when the looting starts, the shooting starts" — Facebook has said Trump's statements do not violate its policies, and that the platform aims to promote free speech.

Trump lashes out at governors, urges them to "dominate" protesters

President Trump berated the nation’s governors in a video teleconference call Monday, calling many of them "weak" and demanding tougher crackdowns on the protests that erupted throughout the country following the killing of George Floyd, according to multiple reports.

The big picture: Trump blamed violence on the "the radical left" and told the governors, who were joined by law enforcement and national security officials, that they have to "dominate" protesters and "arrest people" in order to bring an end to the unrest.
