PhyloGenetic Tree
Classification: Life on Earth, Eukaryotes, Stramenopiles, Phaeophytes.
Phaeophyta: Brown Algae.
Stramenopiles/Heterokontophyta: A major line of Eukaryotes with over 100,000 species that are mostly algae.
Eukaryota: Any organism containing cell(s) with DNA in chromosomes. Most of all living organisms.
Life on Earth: All life on Earth.
Brown Algae are part of Stramenopiles, or Heterokonts. All Heterokonts are though to have evolved from a heterotrophic ancestor that gained photosynthetic qualities. Many assume that Phaeophyta evolved from single-cell ancestors about 200 million years ago, and more specifically, studies suggest that they might have evolved from Phaeothamniophyceae.
