Allopatric diversity was much higher in populations evolving with phages than without (Fig. 1b; sign test of number of times allopatric diversity was greater in populations with phages than without; 8 ...

Divergence of sexual signals in sympatry can arise as a consequence of (1) interspecific competition for resources, (2) selection against maladaptive hybridization, or (3) as a result of selection to ...

Aside from well-known mechanisms of chromosomal polyploidy, examples of homoploid sympatric speciation in plants are rare. Savo-lainen et al. 1 present interesting comparative morphological, ...

Female mate choice has often been proposed to play an important role in cases of rapid speciation, in particular in the explosively evolved haplochromine cichlid species flocks of the Great Lakes of ...

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 ...

The Midas cichlid fish from the crater lakes of Nicaragua are one of the the best known examples for sympatric speciation. They evolved from a source population into a variety of independent species ...

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, ...

Male pregnancy in seahorses may do more than reverse traditional gender roles. It could also influence the way new species form from single populations of these ancient creatures. Male pregnancy in ...
