AJ's information report about the beginning of life on our planet


The beginning of life

Three and a half billion years ago life emerged in the oceans. Then 425 million years ago living things started to move on land. Therefore, life first started in the sea. 

The four elements which made life possible are water, air, light and energy. Life began with simple organisms and have evolved throughout time to the complex organisms living today.

Vegetation covered our planet earth and throughout the millions of years an amazing variety of ecosystems and habitats developed.

Different creatures evolved to survive and thrive in different habitats. The creatures have developed strategies to adapt on land, they also evolved as allies, adversaries and enemies. Life has changed throughout the past billion years, creatures went from a blob until it started to form and evolve into full creatures. 

For the past 162 million years Eutherians evolved into primates. Primates learned to hunt, love and fight. Primates lived for about 2 million years before evolving into humans.

Preserving our planet

Quote:
Man did not weave the web
of life, he is merely a strand
in it. Whatever he does to 
the web, he does to himself.

Life started in the sea 3.6 billion years ago. Sea creatures lived in the sea and moved to land 425 million years ago. Scientists believe that humans came really late. Humans came 8 million years after the earth was created. 

Each living thing on the earth is important for the survival of all living things. For example, if the bees and other pollinators disappear, the tiger will vanish within a year. Mankind will disappear in three years and all other life on earth will soon follow. 

Bees and pollinators are vital to the survival of planet earth because they spread pollen and help the regrowth of plants. Plants are essential to the survival of animals and humans. 

The implications for humans is to help the survival of these important living things. Pollution is causing many negative effects to planet earth. If we don’t look after our planet, more living things will become extinct and human survival will be impossible in the future.

Information report by Siosaia


Evolution of life 

Three and a half billion years ago, there was nothing on planet earth but nucleic acid, lying in the sea. About 1.6 billion years later, bacteria formed in the sea, along with archaea and eukaryotes. At that point, life began in the sea.  About 7 million years later, living things in the sea formed, creating new species such as octopuses, snails and worms. About 600 million years later, animals from the sea, began moving to land thus creating life on land.

The first fish to walk on land was called Tiktaalik, but unfortunately, the Tiktaalik species went extinct long ago. Overtime, fish from the sea would evolve to new, different species. Two hundred and thirty million years later, Tetrapods, amphibians, Marsupials, Reptiles, Birds, and Eutherians became new species. Over time, those species evolved into a lot of different species such as Tuatara, Kangaroos, Elephants and much more.

Eight million years ago, Eutherians later evolved into primates. Primates learned to fight, hunt and a lot of other things we learn now (besides modern-day things), therefore, making primates smarter overtime. 

After two million years, primates evolved into humans. Overtime, humans gained more intelligence and started creating modern technology we use now.
