Latest Allopatric speciation Stories
A newly-discovered species of ant supports a controversial theory of species formation. The ant, only found in a single patch of eucalyptus trees on the São Paulo State University campus in Brazil, branched off from its original species while living in the same colony, something thought rare in current models of evolutionary development.
A new study could deal a major blow to the prevailing theory of how species form – that a new species arises when a barrier prevents reproduction between populations.
Hybrid offspring of different house mice populations show a preference for mating with individuals from their father's original population
Researchers found similar or identical genetic mutations can emerge in separate populations of E. coli evolving in different environments for over 1000 generations, leading the team to conclude that evolution can be fairly predictable.
Thousands of years ago, a genetic mutation occurred which might be the answer to how early humans were able to move from central African and across the continent. This movement has been called "the great expansion."
A genetic study of island lizards shows that even those that have been geographically isolated for many millions of years have not evolved into separate species as predicted by conventional evolutionary theory.
