Allopatric speciation is the evolution of a new species due to populations being geographically isolated over time, which stops gene flow and leads to different selective pressures.
La spéciation allopatrique est l'évolution d'une nouvelle espèce due à l'isolement géographique prolongé, qui arrête le flux génique et expose les populations à des pressions sélectives différentes.
| Text | Allopatric speciation is the evolution of a new species due to individuals from the same population being geographically isolated over a long period of time. There is no gene flow, and there are different selective pressures. |
