New genetic research shows humans’ famed ability to adapt our behaviour and develop new tools and techniques has not always been enough to survive when times have grown tough.
COVID-19 causes lung injury and lowers oxygen levels in patients because the SARS-CoV-2 virus attacks cells’ mitochondria. This attack is a throwback to a primitive war between viruses and bacteria.
In this week’s episode of The Conversation Weekly, we speak with three scientists who study the ways plants and animals evolve in a world dominated by humans.
Microbes are so tiny humans can’t see them without special equipment. But the discovery of 20 new species will help scientists map the evolutionary tree of life.
Bits of viral genes incorporated into human DNA have been linked to cancer, ALS and schizophrenia. But many of these genes may not be harmful, and could even protect against infectious disease.
Climate change is exposing animals to temperatures outside of their normal limits – a new study has found that insects have a particularly weak ability to adjust.

As early modern humans spread across the globe, their gut microbes genetically changed with them. Understanding the origins of gut microbes could improve understanding of their role in human health.
Our ancient ancestors didn’t have clothes or houses – but that constant exposure to the sun helped their skin protect itself from the worst sun damage.
