How long the prokaryotes populated Earth before the evolution of eukaryotic cells which are more complex?
* 3.5 billion years ago the first life arose: prokaryotic bacteria * 1.5 billion years ago eukaryotic cells arose Therefore, prokaryotes were present on earth for 2 billion years prior to the emergence of eukaryotic life.
What is the first life?
Life on Earth began about 3.8 billion years ago, initially with single-celled prokaryotic cells, such as bacteria.
When did prokaryotes arise?
Mid to late nineteenth century.
Where tissues come from?
"tissues" are grouped cells. Cells always come from other cells (at least for the last 4 billion years).

Sort of false - it was about 1.5 billion years ago.
When did the first cells appear on earth?
About 3.5 billion years ago.
When did eukaryotic cells first appear?
2.1 billion years ago
How many years ago did the first cell appear?

How many million years ago did complex cellular structures appear?
4.6 billion years ago the first procaryotic cells were discovered on planet earth
How many years ago did the first simple cell appear on earth according to most scientific models?
4 billion. Carbon dating has led to estimates that the first simple cells appeared on earth about 4 billion years ago.
When did macromolecules first appear?
3.5 billion years ago .
When did invertebrates first appear on the Earth?
The first fossils of invertebrates are at least 3.5 billion years old.
How old are the first cells?
Evidence from microfossils strongly suggests that life arose on the earth long ago. Sedimentary rocks 3.5 billion years old (and perhaps those 3.8 billion years old) contain what appear to be microfossils.
When did the first colonial organisms appear on earth?
