All organisms, including humans, have evolved from ancestral organisms and continue to evolve, although at a rate too slow to witness during one lifetime.
animals, plants, and fungi
Darwin's theory of common descent states that all organisms evolved from past organisms.
Probably a form of bacteria. They evolved into multicellular organisms. Some evolved into plants because they could do photosynthesis
Complex organisms evolved from simple organisms, so simple organisms evolved first.
Unicellular organisms evolved first; and from them evolved the multicellular organisms. But that leads onto another question as to why multicellular organisms evolved.
According to the theory of _____, today's organisms evolved from past organisms.
Colonial organisms have some of the same characteristics of multicellular organisms. The difference between a multicellular organism and a colonial organism is that individual organisms from a colony can survive on their own, while cells from a multicellular organism cannot.
The Cambrian period was when animals evolved hard exoskeletons, probably in response to pressures from predatory animals.

Organisms evolved 550 Ma to form shells. when the Conditions were right for formation of shells.
Unicellular,filamentous and photosynthetic organisms are ALGAE
Multicellular organisms are organisms with more than one cell, the cells of which are usually specialized. A large colonial organism is an organism of many cells that are loosely attached to each other and that show little or no specialization among themselves. Multicellular organisms are capable of surviving on their own while colonial organisms are not.
