Unicellular creatures.
OR
AMOEBA'S which are one celled animals.
An example of a one-celled organism is a bacterium. Bacteria are single-celled prokaryotic organisms that can be found in a wide range of environments. They can be beneficial, harmful, or neutral to other organisms and the environment.
It's called DNA.
No. The term zygote refers to a much broader period at the earliest stages of an organism's development, from the first fusion of sperm and egg to (form a single celled zygote) through many cell divisions (producing a multi-celled zygote) which matures into a blastocyst. So, zygotes can be one celled, two celled, or many celled.
The study of creatures is called zoology. Zoology is the branch of biology that focuses on the structure, classification, behavior, and evolution of animals.
Cnidarians, which is a kind of sponge in the vast amount of different kinds of invertabrates.
no they did not there was only one celled creatures no they did not there was only one celled creatures

One celled organisms are called unicellular organisms.
A small one-celled organism is called a microorganism or a single-celled organism. Examples include bacteria, archaea, and some protists.
unicellular
The first living things on earth were microbes, tiny one-celled creatures.
One celled organisms are called Unicellular organism,they are generally archea, bacteria, protozoa and some fungi and some algae.
The reason single celled organisms were do dominant was because they were the least complex creatures. As single-celled organisms evolve into more complex creatures, their requirements also become more complex and it becomes harder for them to survive.

Protista
Type of one-celled animal is called Paramecium.
