Life History Event Timeline

If all of geological time were the running time of The Lion King (90 minutes/ 1 hour and 27 minutes), the following events would happen at:

Geminga Supernova Explosion 

The Geminga supernova explosion at a distance of roughly 60 pc, roughly as bright as the moon.

 Event #  Your Analogy Value Years Ago 
11 0.02 minutes 1 years
Homo Erectus Tames Fire

The control of fire by early humans was a turning point in the cultural aspect of human evolution that allowed humans to cook food and obtain warmth and protection.

 Event #  Your Analogy Value Years Ago 
12 0.031 minutes 1.6 years
Homo Erectus Exist

Homo erectus is an extinct species of hominid that lived from the end of the Pliocene epoch to the later Pleistocene, with the earliest first fossil evidence dating to around 1.8 million years ago and the most recent to around 300,000 years ago.

 Event #  Your Analogy Value Years Ago 
13 0.04 minutes 2 years
Most Recent Ice Age

This is the ice age before the ice sheet that covered North America.

 Event #  Your Analogy Value Years Ago 
14 0.063 minutes 3.2 years
The Australopithecus Lucy Walks the Earth

Lucy is estimated to have lived 3.2 million years ago,[1][3] and is either directly ancestral to humans, or evolutionarily close to our ancestor, hence it is classified as a hominid.

 Event #  Your Analogy Value Years Ago 
15 0.117 minutes 6 years
Upright Walking Hominids 

Those who are walking on two legs is the trait in the hominid lineage where bipedalism separates the first hominids against the four-legged apes.  This evolution is important to humans as humans fall into the category of bipedalism.  

 Event #  Your Analogy Value Years Ago 
16 1.2 minutes 60 years
Mammals Become Dominant Land Animals

After many long era's, mammals became dominant land animals.  Mammals are considered the dominant land animals because of the fact that they are considered to have all similar characteristics.  

 Event #  Your Analogy Value Years Ago 
17 1.3 minutes 65 years
Dinosaurs Become Extinct

It was said that the dinosaur species completely died out due to a meteor or asteroid that hit Earth.  Before the meteor even made contact with Earth, some dinosaur species were already dying out over time.  Some died because of lack of food, the climate, or being killed by other species.  

 Event #  Your Analogy Value Years Ago 
18 3.9 minutes 200 years
Pangaea Starts to Break Apart

The "Break-up" of the Pangaea was a result of the movement of the Earth's tectonic plates and mantle convection.  Just as the Pangaea were pushed together due to the movements of Earth's plates away of the rift zone;  a new material between the rift caused to push it apart.  The breakage of the Pangaea allows the world to have different as well as separated continents. 

 Event #  Your Analogy Value Years Ago 
19 4.8 minutes  245 years
First Mammals and Dinosaurs 

The first small dinosaurs that appeared on Earth were the "coelophysis". From this point on different types of dinosaurs began to appear onto Earth.  As well as dinosaurs, there were the first mammals which were the "morganucodon".  The first mammals and dinosaurs allowed species to evolve over years of geologic evolution.  

 Event #  Your Analogy Value Years Ago 
20 4.9 minutes 250 years
Permian-Triassic  Period Mass Extinction


The Permian-Triassic Mass extinction is also referred to the Great Dying due to the massive effect the event caused on species.  This extinction event formed the boundary between the Permian and Triassic periods.  This period of mass extinction had the highest results of species that were extinct, with up to 96% of all marine species and 70% of terrestrial vertebrate.  
 Event #  Your Analogy Value Years Ago 
21 6.85 minutes 360 years
Beginning of Pangaea

The Pangaea which is also referred as the Supercontinents formed together to fit like a jig-saw puzzle.  The reason behind why the Pangaea was formed many years ago was due to the Earth's tectonic plates.  Within the Earth's surface there were new materials that formed in between the Earth's tectonic plates at rift zones, which caused the continents to connect at the ends.  

 Event #  Your Analogy Value Years Ago 
22 8.8 minutes 450 years
Formation of Appalachian Mountains 

The formation of the Appalachian Mountains were said to be formed during the time of the Supercontinent Pangaea.  The Appalachian Mountains were formed due to the birth of the subduction zone that was formed from oceanic plate collision with the North American craton.  The Appalachian Mountains are pretty important today as they contain evidences of marine sedimentary rocks and volcanic rocks deformation.

 Event #  Your Analogy Value Years Ago 
23 12.72 minutes 650 years 
Mass Extinction of Sea Plants 

70% of dominant sea plants that went extinct was due to global glaciation or the Snowball Earth.  During this time, all living organisms on Earth had went extinct due to the global glaciation.  If the Earth were to become the Snowball Earth, all of the living organisms would go extinct including humans.
 Event #  Your Analogy Value Years Ago 
24 39.13 minutes 2,000 years
Oxygen formation

Oxygen begins to accumulate into the atmosphere during this time period.  This period is the actually time when oxygen began to enter the atmosphere.  Oxygen is an important part towards life on Earth.  Aerobic organisms would be truly affected if there wasn't any oxygen.   

 Event #  Your Analogy Value Years Ago 
25 47 minutes 2,400 years 
Great Oxidation Event 


The Great Oxidation Event was also known as the Oxygen Catastrophe was the time when anaerobic organisms were poisoned by oxygen.  This event wouldn't really affect humans, since humans can not live without oxygen.  
 Event #  Your Analogy Value Years Ago 
26 48.9 minutes  2,500 years 
First Free Oxygen 


The first free oxygen were found in the oceans and atmosphere.  Due to the rise of concentrated oxygen molecules, uraninity depositions were stopped.  Depositions of uraninites stopped because of the fact that it was soluble with oxygen which led to the beginning of banded iron formations.
 Event #  Your Analogy Value Years Ago 
27 70.43 minutes 3,000 years 
The Sun brightens

At this time the Sun had brighten ten percent higher than the current level.  The current level from 4,567 mya of the Sun's brightness was  70%; however, the Sun's brightness during this time was 80%. 
 Event #  Your Analogy Value Years Ago 
28 74.34 minutes 3,800 years
The Earth's crust solidifies as well as the Condensation of atmospheric water.

The formation of the oldest rocks are founded on the Earth due to the solidification of the Earth's crust.  Atmospheric water begins to condensed in the oceans.  The condensation of atmospheric water is an importance to the life on Earth as it affects the weather.  The water vapors control whether or not the temperature will be warm or cold.  
 Event #  Your Analogy Value Years Ago 
29 84.13 minutes 4,300 years
The melting of the Earth occurs.

The Earth began to melt due to radioactive and gravitational heating which led to the differentiated interior structure.  The Earth melting not only affected the existence of Earth but as well as the living organisms.  

 Event #  Your Analogy Value Years Ago 
30 90 minutes 4,600 years
Formation of the Earth


The formation of the Earth was because of the planetesimal accretion.  After the Earth was formed, it began to heat up.  This heat up occurred due to the decay of radioactive elements but as material melted different elements became visible which led to the Earth's magnetic field.  The Earth forming allowed many years of geologic evolution to occur.
