What cell do scientists think evolved about 1.5 billion years ago?
Scientist believe that prokaryotic cells evolved 1.5 billion years ago.
Which eukaryotic kingdom was the first kingdom to ever be discovered?
The Kingdom Protista was thought to be evolved 1.5 billion years ago through endosymbiosis. The Kingdom Protista contains life-forms similar to those that gave rise to the three kingdoms of multicellular organisms-fungi, plants, and animals.
Was cyanobacteria the first to exist or dinosaurs?
Cyanobacteria. Cyanobacteria are among the earliest forms of life and are thought to have evolved approximately 2.5 billion years ago. These bacteria are thought to have changed the atmosphere of the planet via nitrogen fixation. The first dinosaurs evolved approximately 250 million years ago during the late Triassic.
What are the two basic divisions of the geological time scale?
The largest divisions of the geologic time scale are: Hadean Eon (4.6 to 3.8 billion years ago) Archaen Eon (3.8 to 2.5 billion years ago; this is when the first bacteria existed) Proterozoic Eon (3.8 billion to 542 million years ago) Phanerozoic Eon (542 million years ago through today; this is when the first complex multicellular life forms evolved.)
How long ago is it believed that life evolved into photpsynthesezing plants?
between 3.5 and 4 billion years ago
What kingdom has existed for 3 billion years?
Bacteria.
When did Kingdom Animalia evolve?
Kingdom Animalia is said to have evolved over a billion years ago. The first fossil findings of kingdom Animalia are triploplastic worms.
What cell do scientists think evolved about 1.5 billion years ago?
Scientist believe that prokaryotic cells evolved 1.5 billion years ago.
What is earths oldest form of life?
Single cell organisms date back to approximately 3.5-3.8 billion years old. These are bacteria and archaea.
What is cellular organization?
It basically means all cells are divided into two types: prokaryotic cells and eukaryotic cells. Prokaryotic cells evolved 3.5 billion years ago and have a nucleus. Examples of a Prokaryotic cell include protista, fungi, plants and animals. Eukaryotic cells evolved 1.5 billion years ago and do not have a nucleus. An example of a Eukaryotic cell is bacteria.
What cell's evolved about 1.5 billion years ago?
plant cells
How old are bacteria?
3.5 Billion-Years-Old
Which eukaryotic kingdom was the first kingdom to ever be discovered?

Have plants exitsed for at least 3 billion years?
No. Plants emerged around 1.2 billion years ago, but there were photosynthesizing bacteria 3 billion years ago.
How long ago did bacteria first appear on earth?
Scientists believe that the earth's atmosphere has been in existence for over 3.5 billion years. This is based on the fossil records that are found which date to so many years.
When did the earliest bacteria live about?
3.5 billion years ago
Is the following true or false The ancestor of all eukaryotic cells evolved about 2 billion years ago?
Sort of false - it was about 1.5 billion years ago.
