Rapid Evolution
Popular Mechanics US|July - August 2024
ON APRIL 26, 1986, THE No. 4 reactor at the Chernobyl Nuclear Power Plant in northern Ukrainethen part of the Soviet Union-exploded, sending a massive plume of radiation into the sky. Nearly four decades later, the facility and much of the surrounding area remain uninhabited-by humans, at least.
Rapid Evolution

Animals of all kinds have thrived there in humanity's absence. Living among radiation-resistant fauna are thousands of feral dogs, many of whom are descendants of pets left behind in the speedy evacuation of the area so many years ago.

Scientists from the University of South Carolina and the National Human Genome Research Institute have begun examining the DNA of 302 feral dogs found in and around the Chernobyl Exclusion Zone (CEZ) to better understand how radiation may have altered their genomes-and even, possibly, sped up evolution.

The Tools of Copernicus

WAY BACK IN 1508, WITH ONLY LIMited tools at his disposal, Nicolaus Copernicus developed a celestial model of a heliocentric planetary system, which he described in hist landmark work De revolutionibus orbium coelestium. It was a complete overhaul of our conception of the universe-one that, unfortunately, earned him the ire of the Catholic church for decades after his death-and forever changed the way we look at the stars.
