Question

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?

Gene flow between the two species

Mutations in Howea belmoreana

Natural selection of adaptive traits in both species

Genetic drift of Howea forsteriana

Answer 1

Answer:The evolutionary process that fails to occur is gene flow between the two species of palm trees, Howea forsteriana and Howea belmoreana. Even when the two species grow very close to each other, they do not interbreed, which means that gene flow does not occur. Mutations and natural selection of adaptive traits can still occur in both species, as well as genetic drift in Howea forsteriana.
