Speciation is one of the core issues in evolutionary biology. Sympatric speciation is the evolution of reproductive isolation without geographic barriers in which new species arise from a single ...

Scientists discover at least 11 examples of sympatric speciation on Lord Howe Island. How does a single species divide into two new species? For decades, the prevailing idea among evolutionary ...

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 ...

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 ...

Add The Scientist as a preferred Google source to see more of our trusted coverage. Instead of discarding used polyacrylamide gels, biochemist Palina Kot reshapes them into artworks that reflect the ...

Theoretical studies indicate that while sympatric speciation is possible, the necessary conditions are considerably more stringent than for speciation in allopatry. Sympatric speciation encounters two ...

One of the world's best examples of sympatric speciation, when two species from a single ancestor form in the absence of a geographical barrier, has been found among the swaying palm trees on ...

A new study conducted by scientists from the Indian Institute of Technology Bombay (IIT Bombay), Mumbai published in NPJ Systems Biology and Applications, has shed light on the process of speciation, ...

BERN, Switzerland, May 12 (UPI) --New empirical evidence supports theoretical research that suggests cooperation -- not competition -- is the main driver of speciation and evolution. The theory was ...

Cichlid fishes exhibit some of the most spectacular examples of adaptive radiation, diversifying into dozens of species within individual lakes over remarkably short time frames. Sympatric ...

Three models for sympatric and alleged sympatric speciation are known in evolutionary research. The first model, the most "pure form" of sympatric speciation, describes the development of two species ...
