Multicellular organisms have existed on Earth for approximately 600 million years. The earliest known multicellular life forms appeared during the Ediacaran period, around 600 million years ago, with more complex organisms emerging in the subsequent Cambrian period. This evolutionary transition marked a significant increase in biodiversity and complexity in the history of life on our planet.
What else can I help you with?
What has happened to most organisms that have ever lived on earth?
They have or are fossilizing.
What are the remains of living things that have been perserved in earth's crust?
Fossils are the remains of living organisms that have been preserved in the Earth's crust. This includes bones, shells, imprints, or traces left behind by plants and animals that lived in the past. Fossils provide valuable information about the history of life on Earth and how organisms have evolved over time.
What is organisms that once lived on earth but all of their kind have died out?
The answer is Extinct!
What do fossils tell scientists about living things?
Fossils reveal what organisms lived before us.
Precombrian era what was kiving at this time?
During the Precambrian era, living organisms such as simple bacteria and algae were the primary life forms. These organisms lived in the oceans and played a crucial role in shaping the early Earth's environment. The Precambrian era is also when the first eukaryotic cells evolved, marking a significant milestone in the history of life on Earth.
What animals lived in the Cambrian period?
"one celled organisms" Edit: No; by the Cambrian, life on earth had progressed to include many multi-cellular organisms such as echinoderms, trilobites, sponges and small molluscs.
How long have unicellular organisms have lived on Earth?
they have lived for up to millions of years

Lived on earth and the underworld?
Persephone lives both with the living and in the Underworld.
Who were the other animals lived when dinosaurs were living?
Micro-organisms, mammals, amphibians, reptiles, and many types of marine organisms including fish.
How do scientist know that the first organisms were simple unicellular organisms?
Scientists data can only date back to when these simple, unicelluar organisms lived and thus believe other living organisms evolved through them.
What is the longest living animal on earth that's still living now?
that would be the Horse it has lived for 55 million
