Foxes were once humans’ best friends, study says

Archaeologists originally uncovered the near-complete D. avus skeleton buried alongside a human at Cañada Seca, a site in northern Patagonia, in 1991. Parts of the D. avus specimen were buried alongside a human at Cañada Seca, a site in northern Patagonia. D. avus lived from the Pleistocene Epoch (around 2.6 million to 11,700 years ago) into the Holocene, becoming extinct about 500 years ago. With a similar diet to D. avus, dogs may have helped speed the foxes’ extinction by outcompeting them. Dogs could also have carried and transmitted diseases that sickened the foxes, Lebrasseur added.

Ancient Foxes Lived and Died Alongside Humans

But dogs were not the only ancient canines to become companions. Archaeologists have found traces of foxes living among early communities throughout South America. A team of researchers recently examined the fox’s bones, which were unearthed among the remains of dozens of hunter-gatherers. The team’s findings, published Tuesday in the journal Royal Society Open Science, posit that this fox lived alongside the humans it was buried with. “It’s a practice that had been suggested before, but to actually find it is a nice surprise.”

Renaissance artists may have used egg yolk to protect and alter their paintings, scientists find. Egg proteins mixed into oil paint helps paintings withstand humidity and to prevent wrinkling. In the study, experts found that adding eggs to oil paintings "acts as an antioxidant, slowing down the onset of curing." benjapol congliang/ShutterstockIn examining the effects of using egg yolk proteins in the oil, the scientists found that the egg proteins suppressed the water absorbed in the paint in humid environments. While paintings dried, they also helped prevent yellowing and wrinkling — "a problem even Leonardo da Vinci encountered," the study found.
