As scientists began to build a database of human DNA in the 1990s, it became possible to test these ideas with genes. In his talk, Paabo described how he and…

By comparing individual DNA letters in multiple modern human genomes with those in the Neanderthal genome, the date of that interbreeding has now been pinned down to 65,000–90,000 years ago.…

According to this view, ancient viruses, as with the ones today, could only make copies of themselves by succesfully infecting a host. So they become engines of innovation, using every…

It’s true that the code, as it was understood at the height of the genomic era, had some grounding in material reality. Each of the four different letters stands for…

The genomes of most modern humans are 1–4% Neanderthal — a result of interbreeding with the close relatives that went extinct 30,000 years ago, according to work by an international…

One of the most beautiful aspects of the genetic code is its simplicity: three letters of DNA combine in 64 different ways, easily spelled out in a handy table, to…

For much of the past five million to seven million years over which humans have been evolving, multiple species of our forebears co-existed. But eventually the other lineages went extinct,…

The dish contains a variant of Saccharomyces cerevisiae, known in culinary circles as baker's or brewer's yeast. But Cano didn't get this from Whole Foods. Back in 1995, he extracted…
