Newly Discovered Hybrid Pythons Are Threatening Florida’s Wildlife

A new study has found that some invasive Burmese pythons carry DNA from another snake, which could make them more adaptable—and more dangerous

DNA of Extinct Cave Bear Lives on in Modern Brown Bears

A new genetic study has found that the two species interbred

Chihuahuas were one of the top three breeds represented in the study's sample of more than 900 shelter dogs

Genetic Testing Shows Animal Shelters Often Misidentify Dogs’ Breeds

Shelter staff correctly identified a pup’s primary or secondary breed just 67 percent of the time

Sequencing of Wheat Genome Could Lead to a Breadier Future

It took 200 scientists 13 years to finally figure out the complex genome of the important grain

Scarlet macaws are native to the tropics. So how'd they end up in New Mexico?

A Macaw Breeding Center Supplied Prehistoric Americans With Prized Plumage

This yet-undiscovered breeding center is likely one of the first instances of exotic animal husbandry in the region

Birds don’t fly across wide Amazonian rivers like the Rio Negro.

How Amazon Rivers Play a Role in the Evolution of Birds

Rivers are natural boundaries for evolving populations. But scientists don’t agree whether they create new species or just help maintain them.

European Dogs Devastated Indigenous American Pup Populations

Disease, cultural change wiped out pre-contact populations, leaving no trace of ancient dogs’ DNA in modern counterparts

DNA from this panda skull, found in Cizhutuo cave in southern China, is the oldest panda DNA ever sequenced.
