Which type of organism developed first?

Answer 1

Answer 1

Unicellular organism evolved first.

Answer 2

Both unicellular and unicellular organisms had been created in the meantime by God on the creation of earth. These organisms; by God will; had been evolved to be adapted to nature.

Answer 2

Single-celled organisms, such as bacteria and archaea, are believed to have developed first on Earth, around 3.5 to 4 billion years ago. These simple organisms were the precursors to more complex life forms that evolved later.

Answer 3

Unicellular and multicellular environments may vary. Multi-cellular organisms are able to do more functions, and unicellular is one-cell, so their functions are limited, although some unicellular ones such as thermophiles and photosynthetic bacteria can thrive in any environment with sun or heat. Multi-cellular ones like animals, can be found anywhere active, although different types exist in different places.

Answer 4

There are a number of intermediate steps between unicellular and multicellular organisms. Probably the most clear "midway" point is the colonial organism of which the extant Volvox (link below) is one of the best examples. (Admittedly Volvox itself is only 200 million years to present old, so it is not a remnant of this transition, but is similar to what scientists surmise was part of the transition that led to the development of multicellular organisms.) In a colonial organism, numerous unicellular organisms work in tandem to achieve goals (similar to how geese fly in flocks even though each is autonomous). The required communication would select cells that more effectively communicate with each other, leading to cells that can function as part of the same organism.

Answer 5

Organisms evolved from being unicellular to multicellular. So unicellular came first.

Answer 6

Single celled organisms are the type of organism that developed first. More complex multi-cellular organisms developed not long after this.

Answer 7

Simple prokaryotes

Answer 8

sponges

Answer 9

unicellular
