There are over 7,000 languages in the world and over half of the world’s population is bilingual. But how do all these people use their language? And how do these languages differ from one another? Under the slogan of ‘Interconnecting linguistic diversity,’ the researchers from the Leiden University…

The genetic material of currently living Europeans is partly of Neandertal origin. Were our ancestors successful because they were hybridising and interacting with the local populations they encountered when migrating into new places? Reconstructing our evolutionary trajectory is key for rethinking…
