Lord Howe Island is a volcanic island in the Tasman Sea that is about 11 km long and 2.8 km wide. The island has two species of palm trees, Howea forsteriana and the more abundant Howea belmoreana. The two species do not interbreed even when they grow very close to each other. Which evolutionary process fails to occur?
60
Genetic drift of Howea forsteriana
Gene flow between the two species
Mutations in Howea belmoreana
Natural selection of adaptive traits in both species
