Investigating variations in traits used as mating cues in allopatric vs. sympatric populations of sister-species can help ascertain how trait evolution might favor speciation and co-existence in ...

The fact that sympatric siblings show stronger pre-mating isolation than the allopatric populations suggests that reinforcement of reproductive isolation (reviewed in Servedio & Noor 2003) might have ...

IIT Bombay study reveals how sympatric speciation can occur without geographic barriers, challenging traditional views on speciation.

Unlike allopatric speciation, where complete geographic isolation is involved, or sympatric speciation, where species evolve within the same area, parapatric speciation occurs where neighboring ...

They proposed that sympatric speciation might be a micro-parapatric speciation model. The researchers then suggested that the geographical scale of speciation should be defined based on gene flow ...

While it is widely agreed upon that most speciation events require an allopatric phase – a period in which a species population becomes geographically separated long enough to have it diverge ...

With dispersal, the efficiency of phylogenetic clustering to detect speciation hotspots strengthened considerably (Figure 3) and the “allopatric” mode of speciation displayed as strong associations as ...

Evolutionary biologists traditionally assumed that geographical barriers between animal populations play a decisive role (allopatric speciation): a species is physically separated into two or more ...
