How Genetic Surprises Complicate the Old Doctrine of DNA
For over a century, biologists have had to contend with a complicated picture of genetics, which they’ve only recently begun to understand.
A Mutation Turned Ants Into Parasites in One Generation
A new genetics study of ant “social parasites” shows how complex sets of features can emerge rapidly and potentially split species.
How Pools of Genetic Diversity Affect a Species’ Fate
A new, deeper understanding of how the breeding structure of species affects their genetic diversity is giving conservationists better tools for saving animals.
How Supergenes Fuel Evolution Despite Harmful Mutations
Supergenes that lock inherited traits together are widespread in nature. Recent work shows that their blend of genetic benefits and risks for species can be complex.
When a Gene Illness Discovery Means Breaking Bad News
When scientists discover genes linked to dangerous illnesses in their samples, how should they convey that news to the study participants? The geneticist Cristen Willer had to tackle that challenge.
Catherine Dulac Finds Brain Circuitry Behind Sex-Specific Behaviors
Catherine Dulac is overturning preconceptions about “male” and “female” instincts and opening new avenues to treating postpartum depression.
How Neutral Theory Altered Ideas About Biodiversity
The simple insight that most changes are random had a profound effect on genetics, evolution and ecology.
