Geneticist Pääbo reconstructed the genome of long-extinct human relatives, showing we have more in common with Neandertals than previously thought
Scientists have always been fascinated by the question of human origins: When and where did modern humans—Homo sapiens—first appear? What distinguishes us from other members of the genus Homo and enabled us to develop such unprecedented culture and society?
Ancient DNA Is Difficult to Analyze When Pääbo began working with ancient DNA in the 1980s, the discovery of Neandertals was long a thing of the past. The first fossils of early humans had already been unearthed in the mid-19th century. At first glance this species seemed to be more closely related to modern humans than almost any other. But just how Neandertals were related to Homo sapiens was a subject of repeated controversy in the decades following the discovery.
Soon after, Pääbo joined Allan Wilson’s group at the University of California, Berkeley. Here he dealt, among other things, with the genome of extinct animals such as mammoths and cave bears. But Neandertals were always among his chief interests, Pääbo told Spektrum der Wissenschaft in 2008. Ultimately, he wanted to find out what makes humans human, and which genetic changes contributed to human evolution.
Genes in Common In contrast to the DNA from the cell nucleus, the mitochondrial genome is small. It contains only a fraction of all the genes that a living being possesses and is therefore of limited usefulness. Further progress in the field therefore depended on obtaining the complete Neandertal genome.
