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 ...

Ecological character displacement can only occur in sympatry, and might drive sympatric species to diverge along different ecological dimensions as compared to allopatric species.

Most new species develop in geographic isolation from the original species, a concept called allopatric speciation. It is rare for a species like the parasite ants to evolve from another species ...

Molecular studies might also resolve the long-running debate on the relative importance of allopatric and parapatric modes of speciation.

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 ...
