That number sounds like the onset of the eukaryote organisms. Single cell, membrane bound nucleus and many membrane bound organelles that probably arose by endosymbiosis.

1.2 billion years ago, organisms experienced significant changes such as the development of multicellularity in certain lineages and the emergence of more complex forms of life. This period marked the diversification of eukaryotic organisms, leading to the evolution of various new body plans and adaptations. Additionally, the first evidence of sexual reproduction and the appearance of eukaryotic algae and fungi occurred during this time.

What lived 2 billion years ago?
2 billion years ago, simple unicellular organisms such as bacteria and archaea were the dominant life forms on Earth. These organisms laid the foundation for more complex life forms to evolve over time.
Who was alive 4.5 billion years ago?
4.5 billion years ago, Earth was a young planet still forming, but life had not yet developed. The earliest forms of life, such as single-celled organisms, are believed to have appeared around 3.5 billion years ago.
How long ago was our solar system formed?
Sciences say that the sun was formed 4,600,000 years ago
When did the first colonial organisms appear on earth?
Colonial organisms first appeared on Earth about 600-700 million years ago during the Ediacaran Period. These organisms were multicellular but lacked specialized tissues or organs.
When did complex organisms appear on Earth?
Complex organisms first appeared on Earth around 600 million years ago during the Ediacaran period. These early complex organisms, which were soft-bodied and lacked skeletons, were the precursors to the more familiar plants and animals that evolved later.
What were chimps 1 billion years ago?
There were no chimps 1 billion years ago. At that time all life was single celled organisms and rudimentary multicellular ones.
When did photosynthetic organisms appear?
Photosynthetic organisms, such as cyanobacteria, are believed to have appeared around 3.5 billion years ago. These early organisms played a crucial role in shaping Earth's atmosphere by producing oxygen as a byproduct of photosynthesis.

What is fossilized coral made of?
Dead organisms that were living million / billion/S of years ago.
The first organisms appeard on land between 3.9 and 3.5 billion years ago?
False
How many years ago did the first multicellular organisms appeared on earth?
Approximately 600 million years ago, during the Precambrian era, the first multicellular organisms appeared on Earth.
How long between the evolution of single versus multicellular organisms?
The evolution of single-celled organisms is estimated to have occurred around 3.5 billion years ago, while the evolution of multicellular organisms is believed to have started around 600 million years ago. This means there was a gap of about 2.9 billion years between the evolution of single-celled and multicellular organisms.
What organisms live billion years ago?
Many of these are microorganisms like bacteria and they first formed in the seas.

Describe what happened 65 billion years ago when there was a cosmic collision with earth?
Earth did not exist 65 billion years ago. However 65 million years ago an asteroid collided with Earth, triggering a mass extinction even that wiped out a wide variety of organisms, including the dinosaurs.
