Unicellular plants and animals were first forms of life on Earth
Life began in the oceans, because most life forms are primarily made of water. The first life forms were amoebas and amoeba's are mainly made of water.
Direct Ancestors of Cambrian life forms.
Earth is the planet with the most life forms.
the first lifeforms probably some sort of algae evolved in the sea millions of years ago.
they were probably the first multicelluar life- forms

Plants
DNA I think
Scientists think that the first life forms appeared on Earth about 3.6 billion years ago. These were simple cells that eventually evolved into the abundance of life we see today.
bacteria is not right it is prokaryotes
Life began in the oceans, because most life forms are primarily made of water. The first life forms were amoebas and amoeba's are mainly made of water.
There were no life forms as we know them during the Proterozoic period. With oxygen just then being accumulated in the earth's atmosphere, it brought the first advanced single-celled eukaryotes and multi-cellular life forms.
Fish, they had the first vertebrate
Respect for Earth and all forms of life
The Precambrian Era was the first emergence of complex, multicellular life forms on earth. Jellyfish and segmented worms were discovered to have lived during this time.
The first organisms that were the first forms of life and were able to photosynthesize, were plankton. Most of our oxygen comes from the plankton living in the oceans. They play a big role in our everyday life, sharing that position with plants and all nature life (of plants).
