The Princeton University evolutionary biologist studies how animals are changing due to human activity.

Researchers discover that rattlesnakes change their rattling frequency when a perceived threat approaches—tricking humans into thinking the snake is closer than it really is.

The color morph’s bright yellow hue and its propensity for skin tumors both likely stem from a gene implicated in a dangerous form of human skin cancer, suggesting the animals could make an ideal model for studying the disease.

Scientists injected unfertilized anole lizard eggs with CRISPR-Cas9 to produce albino offspring.

Researchers describe the remains of a clutch of extinct mammal-like animals.

The brown tree snake has wreaked havoc on the island of Guam, but one solution to the problem could lie in the serpent’s own physiology.

See how the tiny island of Guam became overrun with brown treesnakes, and learn what biologists are doing to try to eradicate the invasive species.

The fossil booty includes some eggs with embryo remains inside, and points to group nests involving long-term parental care.

Researchers are trying to recreate an extinct species of the lumbering reptiles by breeding closely related species that contain traces of the lost lineage’s DNA.

The turtle-headed sea snake is losing its stripes, and researchers suggest that the change reflects adaptation to fouled oceans.

The giant lizards have numerous microbicidal compounds in their blood.

Watch Komodo dragons bring down a buffalo.

Geckolepis megalepis escapes its predators by rapidly detaching its fish-like scales.

Anole lizards inhabiting the Caribbean islands display some of the key principles of evolution.

Reptiles, birds, and mammals all produce tiny, bump-like structures during development.   

Researchers confirm the unprecedented endothermic abilities of a South American reptile.

What researchers are learning as they sequence, map, and decode species’ genomes

Researchers are converting carnivores into herbivores in a bid to make raising animals such as alligators, trout, and salmon more sustainable.

Go behind the scenes at labs where researchers are finding ways of switching from meat-based to plant-based feeds.
