The first organisms that appear in Earth's history according to scientists were thermophilic. This meant that the organisms were able to handle the hottest temperatures that were present.

The first organisms on Earth were likely simple single-celled prokaryotes, such as bacteria and archaea, that appeared around 3.5 billion years ago. These early organisms were anaerobic, meaning they did not require oxygen to survive. These primitive life forms eventually evolved into more complex organisms over millions of years.

The vertebrate jaw first appeared in?
The vertebrate jaw first appeared in early jawless fishes, such as the now-extinct Placodermi, around 450 million years ago during the Ordovician period. This evolutionary development allowed for more efficient feeding and contributed to the success of jawed vertebrates.
Who was the first person to whistle?
The first person to whistle is unknown, as whistling likely predates recorded history. Whistling is a natural form of communication and expression that has been observed in various cultures throughout history.
What continent did human first appear?
Human life first appeared in Africa and then proceeded to migrate to other continents.
When did the first vertebrate appear?
vertebrates evolved from micro-organisms many millions of years ago...Another point of view:This actually depends upon your personal view. For the Christian, the story of creation as it appears in the book of Genesis clearly indicates that the first vertebrates appeared on the fifth day of creation, when God created birds, fish and other sea creatures.Oldest known vertebrateA five-centimetre fossil, known as the Ediacara Chordate and uncovered in South Australia is believed to be the oldest vertebrate ever found. The fossil looks like an elongated tadpole and is believed to be at least 560 million years old.
When may homo sapiens have first appeared in Africa?
Homo sapiens, the modern human species, is believed to have first appeared in Africa around 300,000 years ago based on archaeological and genetic evidence. This early population eventually spread out of Africa to colonize the rest of the world.

Multicellular organisms first appeared during the Vendian period.

What organisms first appeared in the Devonian period?
The Devonian Period is sometimes referred to as the age of the fish. Forests and the coiled shell-bearing marine organisms known as ammonites first appeared early in the Devonian.
When did the first multicellular organism appear?
Multicellular organisms first appeared during the Vendian period.
What do scientists think was the of the oxygen in earths atmosphere?
It came from primitive organisms early in earth's history. They were the first organisms to use photosynthesis to make food, by using light to convert Carbon dioxide and water into glucose (food) and oxygen. Since oxygen is a waste product of photosynthesis, it was released into the air. As more and more of these organisms multiplied, large amounts of oxygen were released into the air, forming today's atmosphere.
How long did it take for unicellular organisms to evolve to multicellular?
Answer is not exactly known, as origin of first unicellular organisms is unknown. First multicellular organisms appeared in late Precambrian. Look up Burgess Shale for details.

In what geological era did the first organisms arise?
The first organism appeared during the Proterozoic period. It is estimated that the first organism appeared between 2.5 and 3.8 billion years ago.
What Photosystem is older in terms of evolutionary history?
the first organisms were bacterial organisms having RNA (uracil incorporated) I think any photosystem having to do with bacteria would be your best guess!
