Sympatric speciation is the evolution of a new species without geographic isolation, resulting from reproductive isolation due to genetic mutation (especially polyploidy), habitat differentiation, or sexual selection.
La spéciation sympatrique est l'évolution d'une nouvelle espèce sans barrière géographique, résultant d'une isolation reproductive due à des mutations (polyploïdie), une différenciation de l'habitat ou une sélection sexuelle.
| Text | Sympatric speciation is the evolution of a new species due to individuals being reproductively isolated from a surviving ancestral population. There is no geographic barrier. This can result from genetic mutation (especially polyploidy in plants), habitat differentiation, or sexual selection. |
