Humans share 98% of dna with chimpanzees and bongos think of them as long distance cousins. skull called the dali cranium a thick skull, heavy browed, and a decent sized brain similar to homo sapiens skulls and a bit to ours.Our other relative  the neandertals would bury the dead and make art through caves like how we would do and we  share 1-4% of DNA with them. 1.8 million years ago our ancestors had about the same height, bodysize and shape like humans and walk long distances on 2 legs.After 1 million years ago they discoverd fire then starting cooking and even then 800,000-200,000 years ago is when we would start sendning messages to each other that had different meanings. 320,000 years ago is when we started decorating our tools with red and black crayons and by 300,000 years is when modern human life started. Our brains have developed so much that it increased triple the size.

Scientists found that our bone structures like our skulls are very similar to chimpanzees and bongos from fossils. We have similarities in our behavior like how our ancestors would burry the dead which is a traditioin we still continue and they would walk on their 2 legs for long distances just like humans do.

This event is very important because without evolution we would not have this developed this much knowledge and gain important but simple knowledge like cooking. As we learned new skills and developed our brain overtime through evolution from the help of our ancestors.

Dinosaur extinction 65 million years ago

# data[].attributes.body
A asteroid about the size of 10 kilometers and the speed of 10km per second it was practically a fire ball. As the asteroid got closer to earth the temperatures rised to a extreme temperature. The asteroid was so hot that it was even almost as hot at the sun. It only took seconds for the asteroids to hit the earth. The asteroid hit mexico aswell. There were insanely hot pisces of glass dropping towards earth like as it it was raining. It had reactions with the atmosphere causing acid rain which lats for multiple years. This even caused shockwaves inside the earth and caused a  enormous tsunami to form but it wasn't any ordinary tsunami it was 30,000 times more powerful than tsunamis we have today. But apparently there were a few dinosaurs who managed to live. This caused the air do be foggy and let less sunlight in and caused the environment to get colder. Because of this plants were not able to photosynthesize, affected the food chain and the ocean was too toxic for life. It wiped out 75% of

Dinosaurs were discover by fossils and left over pieces of bone and even foot prints by them. There are many asteroids which consist of oridioum which were even found deep down earth which means there was an asteroid which shows that an asteroid hit through earth.

This event is important because the herbivore dinosaurs would live on plants and they would need to consume more than plant eating animals that we have today due to their size. This caused less amount of  flowering plants.  meaning there would be less fruit and oxygen and with less oxygen there would be less life.

Dinosaurs are types of reptiles that evolved from evolved from their ancestor  dinosauromorphs. Dinosauromorphs looked nothing like T rexes but just reptiles as large as house cats and had skinny limbs but great agility and speed.They evolved  to adapt to the environment through evolution which turned to dinosaurs. The first dinosaurs were the Herrerasaurus and Eoraptor, as well as the plant-eating and dinosaur Pisanosaurus.The Herrarasaurus was a dinosaur with a long tail a small head and a carnivore and 20ft tall. The Pisanosaurus is a small dinosaur only 3.3 ft and a maximum of 1 meter and a herbivore meaning it only eats plants.

Scientists know about dinosaurs from pieces from the animal like bones basically fossils. They learn about the animals by assembling the bones together creating the bone structure of the animal. They calculate the age of the fossils by using the radiomertec method which calculates the age based on the conditions of the bones.

They are important because they helped understand therios of evolution and other scientific concepts like plate tectonics. It also gave more curiosity to scientto investigate how our world works.

One of the first vertebrates were Tiktalkis. It was a fish with long and larger fins which were bendable and they were also able to hold their body weight by using their fins, unlike other fishes. It was able to move its neck independently and had ribs like how our land animals have. The Tiktalkis had advantages on his limbs and fins so it was able to walk on land. These fish were able to breathe on land because they would have lungs meaning that they were able to capture oxygen in through the lungs which is how they would breathe outdoors.

Scientists found out about these vertebrates through fossils. They knew about the first steps of the vertibrates by examining the bones and how they would function like how Tiktaliks  which is how they knew

The energy and structure of many ecosystems, including the whole biosphere ecosystem, ‘depend on vertebrates which can also help scientists study more about them.

Algae are plants ancestors. The algae transferred to fungi to leave over the water and take over land although scientist are not so sure on how algae transformed from water to land. Fungi are everywhere and  share similarities with plants like they both have chlorophyll  they also make food in the process of photosynthesis which is why they think plants came from algae. The first plants were similar to mosses and liverworts. These plants did not have deep roots and they were non vascular plants.

They know this because they believe that agea are plants ancestors because algae and plants share things in common like chlorophyll and they also make food in the process of photosynthesis which is how scientists know where plants came from.

Plants are important because they realse oxygen carbon dioxide which releases oxygen so we can breathe and without them we could die. Plants are also a shelters for many animal so without them animalls could be in danger too.

Cambrian explosion 530 million years ago

# data[].attributes.body
The rise of the oxygen created a sustainable environment and made modern life through evolution. They were more like modern life because some would have gills, feathers, eyes, legs etc. The majority of the animals was marine life possibly because there is more oceans than land on earth. Scientists are not so sure about how the animals came through the earths presence but it is believed to be caused by a explosion creating different varieties of animals and a diversity of them.The animals in the cambrian explosion were more modern and relavent with what we have today due to evolution.

The animals were discovered from fossils and bones from the animal. The fossils would be examined and would go through tests so they can determine the type  and ages of the animal.

This is important because it was able to make most of  marine life and a diversity of them. They are a part of major and important group of fossils. These animals also evolved to modern animals that we can see till this day.

# data[].attributes.body
The oxygen got  through the ocean from droplets through water circulation in the ocean which consisted of some oxygen which helped to produce life through the ocean. The oxygen in the ocean waters gave a sustainable environment to animals. It created animals but scientists are not exactly sure how. There are mostly marine life. It made many varieties of animals such as inarias, kimberleys, sponge,charnia etc.

Scientists calculate oxygen in the waters by using machines which tells the oxygen leves through the ocean. The animals were discoverd from fossils meaning that they found parts of the animal. They would examine and assemble the fossils  together and discover which type of animals it is.

This event is important because it made a numerous amount of marine life which evolved to modern marine life that we find today.

Because of the oxygen, scientists believe that it caused the earth to be like a snow globe cold, icy, and snowy.The microbes caused the earth to freeze because in the process of making the oxygen, They sucked carbon dioxide creating the weather to freeze. After years volcanoes started erupting causing ice to melt which made the earth go back to its normal state. The oxygen also took up a key grass or an important gas from the atmosphere which is what also caused it to freeze

They know this event by examining types of rocks from different events they do this by using a radiometric method. That measures the age and the time. With this, it helps them understand which event it comes from. They also know this by investigating the conditions and the materials from which the event it comes.

This event is important because before the earth was extremely hot and filled with lava and was not a sustainable environment. Because of the snowball incident, it froze Earth causing the temperatures to decrease and after it melted it gave the earth a suitable environment for animals to live.

Breakup of rodinia 750 million years ago

# data[].attributes.body
Rodinia was formed from collisions and fragments from older supercontinents which caused the left over pieces from the collisions creating rodinia. Rodinia is made up multiple of tectonic plates and that is why it is known as a super continent. The continental drifts caused rodinia to split apart. The congo cartoon had collisions between rodinia meaning causing it to break apart.This happened during the Neoproterozoic era.The supercontinent was  large single continent filled with multiple countries and continents which is what we have today. started splitting apart which caused the volcano rocks to break and so the land and water  would absorb more carbon dioxide in. Therefore it caused temperatures to fall and cause snowball earth.

Scientists found out that collisions from the supercontinent left over rock particles. They discover which or where the rock came from. They use a radiomertec method which  measures the age and event of the rocks.

This important because the parts which were split up from rodinia are countries and continents which we have today. So without this event and the breakup we would not have many of these countries and continents which is why this is an important event

First multicellular organism 1.56 billion years old

# data[].attributes.body
The unicellular organisms goes through a process of cell division. The cell gets larger and narrow and it becomes into a oval shape with a indentation in the in middle. The pressure causes the cell to split apart and create 2 cells.The single cell organisms attach to each other and created groups of cells. They formed into a groups to make it difficult for predators to attack them.  The first multicellular organisms were Grypania Spiralis.

Cells were discover by a scienticts in 1665 looked through cork under microscope which was recently invented and he discover cells from the cork.

This event is very important because these cells started spreading through other life and without cells life would not be able to function and cells play very important roles in your body like giving out nutrition and energy as well as humans.

Great oxidation event 2.3 billion years ago

# data[].attributes.body
The oxygen was harmful to many anaerobic life because anaerobic life have elaborate systems of defensives but obligate anareobies can not live in the presence of oxygen so they do not function their defensives and after they die. So this caused to create a large extinction to anaerobic life.

The oxygen got through the atmosphere of earth and had reactions with methanes.Overtime, the mass of the oxygen eventually took over methane creating the great oxidation event. This caused to create many types of minerals like the azurite, malachite, gold, silver, chalcocite, and chalcopyrite.

Scientists discoverd the great oxidation event from rocks. Scientists found out that there were small amount of O2 in shallow waters of the ocean. They say that the rocks were great for study because the rocks were during the  time of an unusual oxygenation event which happened right before the great oxidation event. So scientists know this based by rocks.

This event is important because it was able to make a diversity of minerals. It was able to make 4,500-2,500 minerals. We also need minerals in in our body like for our bones, nerves, and our water balance for our bodies

# data[].attributes.body
2.5 billion years ago there was very poor oxygen. The oxygen developed from microbes, microbes created oxygen by going through a process of photosynthesis. Microbes collect sunlight and sugar similar to plants. Through this process of photosynthesis, it caused to create oxygen and a rich atmosphere sustainable for new life.

A scientist discovered oxygen in 1774 or 1777. He took the gas and also noticed that the candle would burn more brightly in the gass and it was easier to breathe in which is how he discover oxygen.

This is important because without oxygen we would not have a sustainable environment and there would be no new life and humans would not be able to exist.

First life on earth 3.8 billion years ago

# data[].attributes.body
One of the most important elements of life formation was water, energy sources and chemicals. These came from asteroids and comets. The asteroids and comets would hit on earth causing the water and chemicals to crash through the ground The mix of the chemicals then created the first life. It consists of carbon molecules which is came from living things. Microbes were also in hard structures called stromatolies. Its made of sticky mats of microbe tabs and are created into bind sediments. There are minerals inside of the layers which create strong structures for them.

Scientists knew about microbes from stromatolites. Stromatolites are microbial reefs creates by microbes basically fossils. These were event made from microbes. It was made of sticky mats of microbes and bind sediments. The minerals inside caused it to harden which is how scientists know.

This is important because without microbes we would not have any oxygen, we would have no new life and we would not be able to exist without the oxygen.

Formation of earth 4.6 billion years ago

# data[].attributes.body
The gasses and chemicals formed a small ball that came from particles. The particles created a small ball of cloud and dust. It expanded over time from collisions between comets and meteoroids creating early Earth. In the process of meteoroids and comets hitting it it after cooled down so oceans and the atmosphere were formed.

Scientists examine rocks by using the radiometric method. It measures the age and the time for its existence. This helps scientists because based on the rock they can understand which time period the rock came from.

This event is very important because without Earth we would never be able to exist or any type of life earth is possibly the most sustainable place to live on because it has the right temperatures, oxygen, atmosphere, etc.
