Six Eukaryotic Super Kingdoms
Phylogeny(계통
발생론) - Grouping of organisms that
are more closely related to each other.
We
do not know how the six eukaryotic super kingdoms are interrelated or which
lineage branched off at the first. But if we have to pick one, Archaeplastida
is a good choice.
우리는 6개의 진핵계(Eukaryotic kingdom)가 어떻게 연관되어
있는지 모릅니다. 또 어떤 혈통이 먼저 시작되었는지 또한 모릅니다. 시초를
굳이 말하고자 한다면, 원시색소체생물이 가장 좋은 선택일 것입니다.
1. The Archaeplastida(원시색소체생물)
Archae = original or beginning
Archaeplastida = original plastids or
original chloroplasts(염록체)
1)
Groups: green plants, green
algae(조류), red algae, single celled groups
2)
From the Endosymbiont Theory(공생이론), cyanobaterium incorporated into a prokaryotic(원핵생물) cell and evolved in to chloroplast. This is called primary endosymbiosis.
Since all chloroplasts among the archaeplastid organisms seem to originate from
the primary endosymbiosis, scientists think it is perhaps the earliest
eukaryotic lineage(혈통).
2. Excavata(엑스카바타)
1)
Single celled organisms
2)
The group is only supported by
molecular data, not by their morphology. 모양은 다르지만, DNA가
비슷함.
3. Rhizaria(리자리아)
1)
Single celled organisms
2)
Group that is supported by
molecular DNA sequence data only
4. Chromalveolata(크로말베올라타)
1)
Group of many single celled
organisms and multicellular ones: Yellow algae, Golden algae
2)
The taxa(taxon; 분류군) in the group have no general morphological traits in common.
3)
Those that are able to make
photosynthesis all developed their plastids through secondary endosymbiosis.
4)
* Conflicting data suggests
that some chromalveolatates are more closely related with Rhizaria. We operate
with and alternative group named the SAR group
(1)
Stramenopilis (kelp and
diatoms)
(2)
Alveolates (ciliates and
dinoflagellates)
(3)
Rhizaria ( radiolarians and
forams)
5. Amoebozoa(아메바류)
1)
Consists of amoeba
6. Opisthokonta
1)
Group: Metazoans(animals; 후생동물), Fungi(균류), choanoflagellates.
