Diaphoretickes is a large group of eukaryotic organisms. There are over 400,000 species. Most of the Earth's biomass which does photosynthesis is in this group.

All the living things in Diaphoretickes are Eukaryotes: they are complicated cells with organelles. Most plants that make energy out of light are in Diaphoretickes.[1] Only Euglenozoa and blue-green algae are not.

The group includes:

In 2012, this megagroup was defined.[2]

History[change | change source]

Burki led a team of scientists that named Diaphoretickes. They called it the "plants+HC+SAR megagroup"[3] because it has plants (Archaeplastida), haptophytes, cryptomonads, and stramenopiles, alveolates, and rhizarians. That makes the acronyms HC and SAR.

Other scientists call Diaphoretickes the "SAR/HA Supergroup" or "Corticata with Rhizaria."[4] The name "Corticata" comes from Cavalier-Smith's scientific idea that the cortical alveoli of glaucophytes and alveolates both came from the same ancestors.
