Latest Speciation Stories
Birds that are related, such as Darwin’s finches, but that vary in beak size and behavior specially evolved to their habitat are examples of a process called speciation.
As fall fields turn bright with color, what might we learn from roadside rows of sunflowers - and the sunflower seeds widely used to feed birds in colder weather?
A newly-discovered species of ant supports a controversial theory of species formation. The ant, only found in a single patch of eucalyptus trees on the São Paulo State University campus in Brazil, branched off from its original species while living in the same colony, something thought rare in current models of evolutionary development.
Early maize farmers selected for genes that improved the harvesting of sunlight, a new detailed study of how plants use 'doubles' of their genomes reveals.
The Greenish Warbler, long considered an idealized example of a single species that diverged into two as it expanded its range, has a much more checkered family history than biologists previously realized.
Peanuts are seemingly everywhere in the US. From cooking oils to candy bars, peanuts are a part of our lives, and a big business. And now, for the first time, a multinational group of crop geneticists has sequenced the peanut genome.
A pair of new studies from the Wildlife Conservation Society, Idaho State University, and the University of Nevada Reno look at the surprising variety of factors that prevent two closely related species of woodrats from becoming a single hybrid species despite the existence of hybrid individuals where the two species come into contact.
Ever since the nineteenth century scientists have recognized that some regions contain more species than others, and that the tropics are richer in biodiversity than temperate regions.
Natural hybridization between two dolphin species likely helped to bring about the mysterious clymene dolphin, according to a study.
A new study of butterflies found that it’s genetically easier to spin off into a new species than it may have once been thought, even if the two species remain close and interbreed with one another.
The Three-Spined Stickleback, Gasterosteus aculeatus, is a fish native to much of northern Europe, northern Asia and North America. It has been introduced into parts of southern and central Europe. Three subspecies that are currently recognized by the IUCN are Gasterosteus aculeatus aculeatus, which is found in most of the species range, and is the subspecies most strictly termed the Three-Spined Stickleback; its common name in England is the Tiddler, although "tittlebat" is also sometimes...
