Since there have been scientific discoveries of marine Biology thousands of miles inland and that the entire planet was mostly ocean at one stage, one would assume the organisms started in the ocean, but before any oceans were formed, there was mainly molten land, where the organisms could have began. They may have hitch-hiked from passing or plummeting meteorite debris. That would pose many more questions now, won't it? Are any of the organisms indigenous to the planet or are they all from the massive expanse of space?
organisms never evolved < whoever wrote this is an idiot. simply put the answer would be the sea.
The earliest organisms to live on land were lichens and mosses. Animals didn't move onto land until millions of years later.
No, the first life forms were single celled organisms that lived in the ocean.
Unicellular plants and animals were first forms of life on Earth
well life forms, land-forms such as volcanoes and mountains.
Plants
The prevailing theory of the origin of life on earth posits that it began in the oceans.
bacteria is not right it is prokaryotes
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.
Respect for Earth and all forms of life
well life forms, land-forms such as volcanoes and mountains.
Because there were no plant life forms on the Earth when it was first created.
Life/land forms and water
Terrestrial refers to things having to do with the land. Biodiversity is the variation of life forms within a given ecosystem or biome. Combine the two, and there you go! (Terrestrial Biodiversity: the variation of life forms within a given ecosystem or biome that refers to species that inhabit the land.)
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.
