The human species (Homo Sapiens sapiens) started its existence between 110 000 and 50 000 years ago. Its development diverged from the apes about 5 million years ago. The earth has been capable of supporting life for about 3 billion years, and is expected to continue being able to support life for about 5 billion years in the future. If we viewed the period of being able to support life as 24 hours, then we are now about 9 o'clock in the morning, humans diverged from the apes about a minute ago and the human species started to exist 1-2 seconds ago. However life on the earth has only existed for about 1% of the time the earth has existed..
Well, the Universe has only existed for about 14.7 billion years, so the first 433 billion years were uninteresting. Then the Earth only formed about 4 - 5 billion years ago, so the atmosphere was very tenuous until that time.
The Paleozoic, the Mesozoic and the Cenozoic are the 3 Eras of the Phanerozoic Eon.The Paleozoic Era occurred between 542 and 251 million years ago. It lasted 291 million years. It was made up of 6 geological periods. The Cambrian Period(542 - 488Ma), the Ordovician(488 - 443Ma), the Silurian(433 - 416Ma), the Devonian(416 - 359Ma), the Carboniferous(359 - 299Ma) and the Permian(299 - 251Ma).The Mesozoic Era occurred between 251 and 65.5 million years ago. It lasted 185.5 million years. It was made up of 3 geological periods. The Triassic Period (251 - 199.6Ma), the Jurassic(199.6 - 145.5Ma) and the Cretaceous(145.5Ma).The Cenozoic Era occurred between 65.5 million years ago to now. It has lasted 65.5 million years to date. It has been made up of 3 geological periods to date. The Paleogene(65.5 - 23.03Ma), the Neogene(23.03 - 2.588Ma) and the current period the Quaternary Period (2.588Ma - Now)
According to the fossil record, multicellular life forms first appeared about 570 million years ago. This means multicellular organisms appeared almost 3 billion years after the first evidence of life.
archaebacteria
Microorganisms such as bacteria and archaea have existed on Earth for at least 3 billion years. These simple, single-celled organisms are some of the earliest forms of life on our planet.
The kingdom that has existed for at least 3 billion years is the Kingdom Bacteria. Bacteria are single-celled organisms that have been on Earth for billions of years and are among the oldest forms of life on our planet.
3 to 4 million years ago
As old as history itself, at least a few million years.
Triceratops, Tyrannosaurus, and Alamosaurus were three of the dinosaurs that existed 65.5 million years ago. They were among the last dinosaurs, and died out as a result of the asteroid impact at Chixculub.
No hominids had evolved 5.2 million years ago. The first known hominid was H. habilis, and they existed about 3 million years ago. Our ancestors that were alive between 5.2 and 5.8 million years ago were the Ardipethicus genus, which lived in the rainforest, walked bipedally, and had an opposable big toe.
Hominids have existed for approximately 2-3% of the total time that life has been present on Earth, which is estimated to be around 3.5 billion years. This means that hominids have been around for roughly 6-7 million years.
Homo sapiens have existed for approximately 300,000 years. They are the only surviving species of the genus Homo.
The Maastrichtian Age is the final age of the Cretaceous Period, from 70-65 million years old. Over 100 dinosaurs were alive at this time. Tyrannosaurus, Triceratops, and Ankylosaurus are just 3 of these.
There are three million years in three million years that is written 3,000,000. There are 36,000,000 months or 156,532,371 weeks or 10,957,266,000 days in three million years.
