Ancient DNA Yields Snapshots of Vanished Ecosystems
Surviving fragments of genetic material preserved in sediments allow scientists to see the full diversity of past life — even microbes.
In Ecology Studies and Selfless Ants, He Finds Hope for the Future
For more than six decades, the influential biologist Edward O. Wilson has drawn connections between evolution, ecology and behavior, often sparking controversies inside and outside of science.
Rapid Oxygen Changes Fueled an Explosion in Ancient Animal Diversity
Skyrocketing animal diversity a half-billion years ago was linked to spikes and dips in marine oxygen levels, according to a detailed geological study.
Icefish Study Adds Another Color to the Story of Blood
The rainbow of pigments that animals use for blood illustrates a central truth of evolution.
New Squid Genome Shines Light on Symbiotic Evolution
Researchers hope that the genes of a glowing squid can illuminate how animals evolved organs for beneficial bacteria.
Artificial Intelligence Finds Ancient ‘Ghosts’ in Modern DNA
With the help of deep learning techniques, paleoanthropologists find evidence of long-lost branches on the human family tree.
Fragile DNA Enables New Adaptations to Evolve Quickly
If highly repetitive gene-regulating sequences in DNA are easily lost, that may explain why some adaptations evolve quickly and repeatedly.
