The process of speciation allows a single species to diverge into two. Dive into the different versions of this process, including “allopatric speciation” and “sympatric speciation,” and discover how ...

It has long been thought that dramatic changes in a landscape like the formation of the Andes Mountain range or the Amazon River is the main driver that initiates species to diverge. However, a recent ...

Mate choice, competition, and the variety of resources available are the key factors influencing how a species evolves into separate species, according to a new mathematical model that integrates all ...

Species of Isoetes are notorious for the difficulties they present in identification. These difficulties are attributable to a series of habitat adaptations that have resulted in morphological ...

Evidence is presented to indicate that catastrophic selection in ecologically marginal populations has had a prominent role in speciation in the genus Clarkia. The following observations compellingly ...

Despite their small size, organisms smaller than a thousandth of a meter (1 mm) contribute greatly to biodiversity and ecosystem function. Unfortunately, categorizing small organisms—even defining ...

The Western Black Rhinoceros, Pyrenean Ibex, and Javan Tiger are just some of the animals that have gone extinct in the last 50 years due to human activities. Surprisingly, it turns out, human ...

Many marine mammals and seabirds degrade methylmercury mostly in the liver. Atlantic bluefin tuna appear to lean on the ...
