Life History Event Timeline

APES LIFE HISTORY ANALOGY If all of life's history (4.6 billion years) were 5280 feet in a mile,then the following events would happen at

Most of the world today is filled with skyscrapers. Humans are using advanced technology, that heavily pollutes the Earth.

In the century before the one we are in, 14/15  years ago we were born.

On the earth, 1.8 MYA- today, it is the Quaternary period or also called "The Age of Man". In the Quaternary period, 149 years ago, was the civil war which is a big event for America.

The Earth was slowly warming. There were glaciers much larger than they are today, and were extremely cold. Later on, there was the official ending of the ice age.

Our species, homo-sapiens, began to evolve close to 200,000 years ago. Their bodies tended to be more muscular generally and taller than the neanderthals, but less massive. The neanderthals and homo-sapiens both descended from homo-heidelbergensis.

The Neogene period started off with the continents crashing into each other. Italy hit Europe making the Alps, and so on for many areas. South America headed north and merged with North America making Panama. Sea levels were also significantly lowered, allowing species to cross the land bridge from Asia to North America. Animals migrated in many ways across the new land forms. Asian and African diverged from their ancestors, the chimpanzees, and learned how to walk on two feet as well as to use their hands.

25 Million years ago, there were penguins much larger than those today. Mostly located in New Zealand, the bird paradise 25 million years ago, the Kariruku Penguin rivaled average human height. The penguin was slimmer with longer flippers made for the shallowly flooded landscape that New Zealand harbored at the time.

On the earth, 38 million years ago, it was the Oligocene period. In this period an Archaeotherium, also known as the "giant pig" , and the Brontotheres appeared from the horses.

On the earth, 55million years ago, it was the Eocene period. In the Eocene Period, small horse type animals started to evolve. One was called the Uintatherium, and the other was the Hyracotherium. Also, in this time period, plants started depending on insects more to pollinate them.

In the Palaeocene period, dinosaurs, pterosaurs, and giant marine reptiles became absent from Earth. To fill the void, the mammals took upon the opportunity to come out of hiding and dominate the day. The continents continued to drift apart, and Australia separated from Antarctica. A sudden temperature spike occurred, and raised water temperatures killing off some single celled organisms. Following, the climate cooled and forests gave way to tons of grazing herds of mammals.

Dinosaurs ruled during the cretaceous period. Many flowers and plants spread across the landscape due to insects. At the end of the period, dinosaurs would disappear and their place would be taken by mammals. The cause for the dinosaurs vanish has been up for debate, whether volcanism or an extraterrestrial impact could have wiped most of the Earth's population at the time.

12 230 ft 200 MYA
Throughout the Jurassic period, both Laurasia and Gondwana began to split again. Laurasia become North America and Eurasia. Gondwana became South America and Africa. New oceans flooded in between. Climate in all areas started to change in different ways, including deserts turning into a greener area. The first bird also appeared during the Jurassic Period.

90% of the Earth's population was destroyed during the Triassic Period. It then gave birth to the repopulation of the planet. The dinosaurs made their first appearance in the triassic period, as well as rodent sized mammals. Across the period, Pangaea started to split into Laurasia and Gondwana by the end.

The Permian Period began about 300 Million years ago. It ended with the largest mass extinction in Earth's history, and had many extreme climate changes. This was due to the emerging supercontinent of Pangaea. Cold blooded reptiles found it easy to adapt to the climate changes especially with their scaly skin.

360 Million years ago marked the start of the Corboniferous period. It contained large coal deposits underground found in Europe, North America, and Asia. These were lush and tropical regions.

Devonian period started around 412 billion years ago, at this time animals that started to evolve were: Ichthyostega, Hemicyclaspis, Coelacanth, Dunkleosteus, and bothryolepis. while the Devonian period went on, the Silurian period was still going on. In the Devonian period which was 58 millions years, the first amphibians came around, which were called Ichthyostega. Also, the very first invertebrates came around, which were the Goniatites.

Silurian period started around 435 million years ago, at this time the animals that started to evolve were: Eurypterids, Agnathans, and Acanthodians. The Silurian period lasted for about 23 million years, and around 11 million years into the Silurian period, the Agnathans began to evolve. The Acanthodians were the earliest known, jawed fish, the Agnathans were jawless fish, and Eurypterids were a extinct group from the Arthropods, that could reach the length of 7 and a half feet. Also, this time period they developed the very first plants.

Ordovician period starts around 492 million years ago, at this time the animals that developed at this time were: Echinoids, Crinoids, and Starfish. The Ordovician period lasted for around 57 million years until the next period came into play.

Cambian period starts on the earth around 570 million years ago, which included of the animals like: Blvalves, Sponges, Trilobites, Algae,  and jelly fishes. The Cambian period lasted for around 78 million years, and about 39 billion years into the Cambian stage Coral, Nautiloids, and Graptolites.

In the Vendian/Ediacaran Period, multi-celled animals started to appear, one of those animals were sponges.

670 million years ago, the first organisms with a brain or nervous system appeared in worms.

Eukaryotes really diverse and have an extreme population increase by 1.7 BYA.

There was an oxygen revolution due to photosynthetic organisms. This created the first global pollution crisis and killed many life forms. Aerobic respiration became possible as well. There was also the formation of ozone

There were the first Eukaryotes with cells that have a nucleus.

On the Earth, 3800 million years ago, there was the oldest evidence of life, which was blu-green algae called archaens and bacteria. The bacteria grows in the oceans, which were started from the rain, that formed the oceans. Once it grows in the ocean, it starts letting oxygen in to the atmosphere.

26 4362 ft 3800 MYA
Earth began to rain for quite some time, and formed oceans. At this time, there was no oxygen in the atmosphere.

27 4591.3 ft 4000 MYA
The Earth began to solidify and formed the oldest rocks. The first amino acids also formed.

Bombardment of the Earth by asteroids stopped 400 Million years ago. These asteroids were the size of Kansas, and it sterilized Earth. 

 Event #  Your Analogy Value MYA
29 4936 ft 4300 MYA
4300 million years ago the iron catastrophe occurred. The Earth's heat after being formed was significant, to the point where a critical condition was reached, and the material was molten enough to move. Iron and nickel sunk to the center of Earth to form the core.

 Event #  Your Analogy Value MYA 
30 5280 ft 4600 MYA 
4600 Million years ago,  there was the formation of the Earth by accretion of stellar dust and gases, also known as the formation of Earth.
