The team collected three specimens, all found near the ancient citadel of Machu Picchu, and determined it was a new species, ...

Allopatric speciation occurs when a species is separated into groups by physical barriers. Prevented from mating with one another due to the presence of some sort of physical boundary — such as a sea ...

The biological equivalent is "allopatric speciation," an evolutionary process in which one species divides into two because the original homogenous population has become separated and both groups ...

Trait data from more than 1,000 different vertebrate species suggests that new species often arise not because of pressures from different environments, but because of prolonged geographic ...

Two new owl species have been identified in the Philippines, and researchers say the birds' songs led them to the discovery. "More than 15 years ago, we realized that new subspecies of Ninox hawk ...

Instead, they often use the morphological species concept, where extinct species are identified using similarities in their size and shape. ... also known as vicariant or allopatric speciation. This ...

This is likely evidence of a process called allopatric distribution, when one species is split by a geographic barrier and evolves into a distinct species. “Such exceptional diversity, driven by ...
