Chromalveolata was a eukaryote supergroup present in a major classification of 2005, then regarded as one of the six major groups within the eukaryotes. [3] It was a refinement of the kingdom Chromista, first proposed by Thomas Cavalier-Smith in 1981.

Chromalveolata Current evidence suggests that species classified as chromalveolates are derived from a common ancestor that engulfed a photosynthetic red algal cell, which itself had already evolved chloroplasts from an endosymbiotic relationship with a photosynthetic prokaryote.

Chromalveolata is a eukaryote supergroup first proposed by Thomas Cavalier-Smith as a refinement of his kingdom Chromista, which was first proposed in 1981. It was proposed to represent the result of a single secondary endosymbiosis of a line descending from a bikont with a red alga that became the progenitor of chlorophyll-c containing plastids.

Chromalveolates include very important photosynthetic organisms, such as diatoms, brown algae, and significant disease agents in animals and plants. The chromalveolates can be subdivided into alveolates and stramenopiles. A large body of data supports that the alveolates are derived from a shared common ancestor.

One of three domains of life, parallel to Bacteria and Eucarya (Eukaryota); it contains unicellular microorganisms devoid of a nucleus.

Chromalveolata All descended from a heterotrophic ancestor that acquired a red algal plastid by secondary endosymbiosis; plastid has been lost in some subgroups, such as the ciliates. Many are heterotrophic.

Ten years ago, Cavalier-Smith proposed that these plastids were all derived from a single endosymbiosis, an idea that was dubbed the chromalveolate hypothesis.

Chromalveolata is a eukaryote supergroup first proposed by Thomas Cavalier-Smith as a refinement of his kingdom Chromista, which was first proposed in 1981. The origin of the Chromalveolata was thought to be a secondary endosymbiosis between a bikont (cell with two flagella) and a red alga. [1] This union led to plastids containing chlorophyll ...
