Did humans truly domesticate dogs?

Though archaeology can help us pin down the when and where of dog domestication (current thinking is that it happened at least 15,000 years ago in Europe, Asia, or both), bones are mostly silent on the how and the why of this story. By studying other canids like foxes and wolves, and by analyzing dog genes, behavior, and brains—their sweet, friendly, trusting brains—researchers are developing new ideas about how the big bad wolf became the dear little dog. 

A Genetic Ghost Hunt: What Ancient Humans Live On In Our DNA?

When the Denisovan genome was sequenced soon after, in 2012, it revealed similar instances of interbreeding. We now know that small populations from all three Homo lineages mixed and mingled at various times. The result is that our DNA today is speckled with contributions from ancient hominin groups who lived alongside us, but did not survive to the present day. Genes from Denisovans and Neanderthals are not present in everyone’s DNA — for example, some Africans have neither, while Europeans have just Neanderthal genes. But, these genetic echoes are loud enough to stand out clearly to scientists.

This Bird Went Extinct and Then Evolved Into Existence Again

The Aldabra white-throated rail, a flightless bird that lives on its namesake atoll in the Indian Ocean, doesn’t look like anything special at first glance. But the small bird has big bragging rights, because it has effectively evolved into existence twice after first going extinct some 136,000 years ago.

From Nazi to football hero: the incredible story of Man City’s Bert Trautmann

Famous for playing the 1956 FA cup final with a broken neck, Trautmann went from Nazi soldier to goalkeeping legend and symbol of truth and reconciliation. Now, his life is the subject of a new film

NASA’s Space shuttle rises from the ashes to power new vehicles

IN 2011, THE storied space shuttle flew for the last time. Three spacecraft survive in retirement as specimens in museums around the country. But the program isn’t dead yet: Many of its parts are popping up as zombie components in spacecraft now in development.
