How life started!!!

Genomics: how life started

3.6 billion years there was nothing, just nucleic acid everywhere around the sea. Then approximately 1.6 billion years ago bacteria was forming in the sea, followed by archaea and eukaryotes and then at that point on life started in the sea. About 7 million years later animals that were in the sea formed, along with fungi on land. The about 600 years later, Animals from the sea began life on land.

The first ever fish to walk on land was tiktaalik fish, But then unfortunately, the tiktaalik fish species went extinct a long time ago. During overtime, fishes that were from the sea will evolve to new, different species. Then after about 230 million years ago, tetrapods, amphibians, marsiuphins, reptiles and birds, and eutherians then became new species. Then as time went on those species evolved to many other species.

8 million years ago ( which 162 millions years ago ) eutherians evolved to primates, so 2 years later primates learnt how to fight, learnt how to protect, and also learnt how to hunt things, but they learnt things we learnt now, but before 8 millions years ago, 50 million years ago even-toed ungulates became a new species such as hippopotamus, pargoa, camel, and gemsbok. Then 8 million years ago, odd toed ungulates, like wolves, rhinoceros, horses and lions, carnivores 42 millions years ago carnivores became a new species. 

Going back to the 8 millions  years ago, primates and apes evolved to humans, making us almost the last living thing to come to earth, we humans came to earth 8 million years ago but then 100 years or 150 years ago the earth, and living things have been, getting destroyed because of climate change, climate change has been getting worse each year, as the ice of antarctica melt because of the sun the sea levels of the ocean will melt causing the sea to rise, but not only that, there are multiple things going on like air pollution, water pollution rubbish.

Here's a fact if bees were to become extinct all life on earth will die because, bees are pollinators and they go from plant to plant, flower to flower and tree to tree, but you see that everytime they go to another plant to the other, the bees are carrying pollen and if they go to the plant pollen that was on the bees will regrow that plant to make it live for a longer time, and if bees go extinct within a year tigers, lions and other animals will go extinct, and within 3 years us humans will go extinct, thats why its important to keep this earth clean otherwise we are gone, because there is a theory that in 12 years from this day on earth will come to an end unless we stop polluting the earth.
