Anole species in the Greater Antilles have been sorted into six ecomorphs. Species within each ecomorph occupy similar ecological niches and have similar morphology. Two hypotheses have been proposed to explain why each island has similar ecomorphs. The Common Ancestry Hypothesis proposes that each ecomorph evolved once and species belonging to the same ecomorph are closely related despite living on different islands. The Convergence Hypothesis proposes that the ecomorphs evolved repeatedly and independently on each of the islands and species belonging to the same ecomorph are similar due to convergence (not common ancestry). Which hypothesis is supported by the phylogeny shown below? Briefly explain. Twig-Puerto Rico Canopy- Puerto Rico Grass- Puerto Rico

Evolutionary lineages

An evolutionary lineage is a series of populations of organisms that descend from a common ancestor. Each species in the lineage is the direct consequence of evolutionary change from a common ancestor. A phylogenetic tree is generally used to display lineages visually. Lineages are components of the phylogenetic tree of life. Molecular systematics procedures are widely used to predict lineages.
