Genomic study: our capacity for language emerged at least 135k years ago (phys.org)
It is a deep question, from deep in our history: when did human language as we know it emerge? A new survey of genomic evidence suggests our unique language capacity was present at least 135,000 years ago. Subsequently, language might have entered social use 100,000 years ago.

The Prehistoric Psychopath (worksinprogress.co)
Life in the state of nature was pleasant, cooperative and longer than you might think. Most of our ancestors avoided conflict. But this made them vulnerable to a few psychopaths.

What fossilized dino feces can tell us about their rise to dominance (arstechnica.com)
Paleontologists have long puzzled over how the dinosaurs—originally relatively small and of minor importance to the broader ecosystem—evolved to become the dominant species some 30 million years later. Fossilized feces and vomit from dinosaurs might hold important clues to how and why this evolutionary milestone came about, according to a new paper published in the journal Nature.

How human brains got so big: cells learned to handle stress that comes with size (nature.com)
Humans have evolved disproportionately large brains compared with our primate relatives — but this neurological upgrade came at a cost. Scientists exploring the trade-off have discovered unique genetic features that show how human brain cells handle the stress of keeping a big brain working. The work could inspire new lines of research to understand conditions such as Parkinson’s disease and schizophrenia.
