evolution of first multicellular organisms
Protists are eukaryotes and live in water or in watery tissues of organisms. Some protists resemble plants in that they produce their own food by photosynthesis, while others resemble animals in consuming organic matter for food. Protist cells are often structurally much more elaborate than the cells of multicellular plants and animals. Protists include the protozoans, most algae, diatoms, oomycetes, and the slime molds. Also called protoctist. Heterotrophic protists are the ones that need to feed on other organic matter. They Cannot produce their own food via photosynthesis or other internal chemical reactions.
All protists are eukaryotic (have a nucleus), most live in water. They are the "ancestor organisms" because they were the first organisms ever to exist.Protists are simply organisms that don't fit into any of the other kingdoms.The great diversity of form, habitat, mode of nutrition, and life history exhibited by eukaryotes suggests they evolved several times from various groups of prokaryotes. This makes the Protista a polyphyletic group. Eukaryotes are generally larger, have a variety of membrane-bound organelles, greater internal complexity than prokaryotic cells, and has a secialized method of cell division (meiosis) that is a prelude to true sexual reproduction. Protists might be viewed as a group from which the other eukaryotic kingdoms evolved.

Eukaryotic. This means that it has advanced cell structure, including a nucleus. Protists were the first Eukaryotes.

Animal-like protists that use structures called pseudopods to trap their food. These animal-like protists are known as protozoans and are believed to be the first evolutionary animals. .
The first eukaryotes are most likely to belong to the Protista kingdom. These are mostly multicellular organisms with the earlier ones including organisms like Kneallhazia solenopsae and many more.
The ancestors of the Maori people from Polynesia.
The Cell Wall was not present in the first eukaryotes.

The original Filipino ancestors are known today as Negritos or Aeta. It is believed that they had lived 40,000 years ago.
Oxygen came before Eukaryotes and this is known due to the fact that Eukaryotes need oxygen to live.
The early Spartans, or Dorians, first entered Greece in about 1000 BCE. It is believed that they came in small groups, rather than a large force.

(True ) i think the first protist on earth were the paramecium, ameoba, euglenea, and volvox
