Which species on the cladogram represents an outgroup?

Expert Solution & Answer

Summary Introduction

To determine: The species on the cladogram that represents an outgroup.

Concept introduction: Cladogram is a diagram that represents the hypothetical relationship between different groups of animals known as phylogeny. It is used to visualize the similarities and commonly shared characters of different groups of animals. A cladogram uses lines to demonstrate branches that end at a clade. A group of animals whose members possess one or more derived characters is called as a clade.

Answer to Problem 1DAA

Correct answer: Eurasian rosefinch (Carpodacus) species on the cladogram represent an outgroup.

Explanation of Solution

As given in the problem statement, membership of the po’ouli (Melamprosops phaeosoma) was controversial in Hawaiian honeycreeper clade when it was discovered in 1973. Later in the year 2011, the researchers deciphered phylogeny of 19 Hawaiian honeycreepers including the po’ouli. They sequenced mitochondrial and nuclear DNA samples from the honeycreepers and 28 other birds (outgroups). A outgroup is a reference group of organisms where the phylogenetic tree would be rooted. Refer Fig. 18.10, “Phylogeny of Hawaiian honeycreepers”, in the textbook. The cladogram was made using the comparison of mitochondrial DNA (whole genome) and 13 nuclear DNA loci of 19 Hawaiian honeycreepers and 29 other finch species. On the basis of the tree, Eurasian rosefinch (Carpodacus) species are visualized as common ancestors, and thus they represent an outgroup.
