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.

In a phylogenetic tree, Species 1 and 2 are distantly related to one another but are both darkly pigmented. Species 3 which is unpigmented is a sister taxon to Species 2. The common ancestor to all three species is darkly pigmented; thus, this trait in the phylogeny is considered to be a - A. homoplasy. B. synapomorphy. C. apomorphy. D. symplesiomorphy.
Phylogenetic trees are constructed based on parsimony the idea that the simplest answer is the misy likely. Explain why a parsimonious tree is a likely but not the only possible answer when depicting evolutionary relationships.
Species A was recently discovered and its DNA sequence was compared to the DNA of the four previously known species from the same genus. The comparison revealed this particular species is the most recent one, the one that diverged last. Show the mismatched nucleotides between these DNA sequences (mark them and count them) and then draw a phylogenetic tree that shows their relationship.
