WebA recent study of a pair of sympatric species of palms on the Lord Howe Island is viewed as providing probably one of the most convincing examples of sympatric speciation to date. Here we describe and study a stochastic, individual-based, explicit genetic model tailored for this palms system. Overall, our results show that relatively rapid ...

WebThey may exhibit lots of beneficial traits but, like mules, they are often sterile. Certainly this is often the case, especially for hybrid animals, however, more and more we are finding that hybridization has resulted in multiple legitimate speciation events, especially in plants.
