Snake venom evolved in fits and spurts
The cocktail of toxins in snake venom experienced constant change with pulses of rapid evolution over the last 60 million years, according to a recent study in the Proceedings of the Royal Society B. Venom, the researchers report, has changed … Continue reading

Molecular evidence supports Darwin’s adaptationist view, informing the debate over what drives evolution
Myriad genetic differences distinguish the genomes of two species. What fraction of those differences arises by positive natural selection versus random genetic drift is a central question and topic of debate in evolutionary biology. A recent study in Nature Ecology … Continue reading

Study uncovers new privacy worries for direct-to-consumer DNA testing
Genetic testing services let consumers analyze their DNA to learn about their heritage, their relatives, and their risk for certain heritable diseases. But access to such personal data hasn’t been without controversy, stoking privacy fears. A recent study in eLife … Continue reading

For camouflaged animals, a quick dash is best to avoid detection
A hunting falcon flying over a field might not see a camouflaged rabbit hidden in the grass. But if that rabbit loses its nerve and runs, then the falcon will see its meal. Movement gives away even the best disguises. … Continue reading

Cooperative defense against disease may have helped insects evolve complex societies
The lifestyles of insects, such as bees and wasps, range from simple solitary arrangements to more recently evolved, highly complex family social structures. One major factor that allowed social complexity to evolve may have been insects’ ability to defend their … Continue reading

Mediating conflict helps community forestry schemes succeed
Empowering people to manage the forests near their homes is one tool of sustainable development. Widely known as “community forestry,” the notion originated in the 1970s with the dream of fair, equitable, and sustainable forest use. But achieving those aims … Continue reading
