Sar or Harosa (informally the SAR supergroup) is a clade that includes stramenopiles (heterokonts), alveolates, and Rhizaria. The first letter of each group provides the “SAR” in the name. The SAR include taxa that are very diverse including some of the most important photosynthetic organisms on Earth. This supergroup can be divided into three clades: the Stramenopiles, the Alveolates and the Rhizaria. Brown Alga is a Stramenopile, while Foram & Radiolarians belong to Rhizaria.

The phylogenetics tree below shows evolutionary relationships among 8 species. Males of these species are either blue (b) or red (r) in color, the color being indicated next to each species name.
Based on the principle of parismony, which of the following statements best represents the evolution of male body color in this set or species?
The most recent common ancestor of all 8 species was blue; red evolved independently 5 times.
The most recent common ancestor of all 8 species was blue; red evolved independently 4 times.
The most recent common ancestor of all 8 species was red; blue evolved independently 3 times.
The most recent common ancestor of all 8 species was red; blue evolved independently 2 times.
