If this event did not happen, humans did not appear on Earth
Even dinosaurs and other animals do. All that exists is a single-celled organism.
How animals appear and evolve are still the mysteries of the scientific world. However, it seems that we can finally solve this mystery, through the discovery of the Australian National University.
Basically, life has been formed on Earth for billions of years. But before 650 million years ago, that life was primarily bacteria, viruses and other basic multicellular organisms. Only when an unprecedented large-scale event occurs, things start to change.
Life on Earth used to have only bacteria and unicellular organisms.
Accordingly, the team found evidence that an ice age occurred 700 million years ago , turning the Earth into a gigantic snowball globe for 50 million years.
By the time the ice age ended, the creatures stuck in the ice rushed into the newly formed ocean and ocean. This process has enabled the green algae to grow extremely strongly, thereby laying the foundation for evolution, which then forms terrestrial animals.
Specifically, the team surveyed the rock layer in Central Australia - dating back 650 years, and they found algae molecules since ancient times.
"Before the development of the Earth today, there is a horrible event that has turned our planet into a snow globe for 50 million years" - quoted Jochen Brock, associate professor of research. .
The evolution process has received appropriate support to create a more complex ecosystem.
"The icy layer has stored a huge mountain of nutrients, then when the ice melts, the river swept all the way to the sea."
According to Professor Brocks, that huge amount of nutrition, plus the warming temperature of the Earth, created an ideal condition for life to develop explosively, creating more complex life forms.
"As a huge source of energy, evolution has received adequate support to create a more complex ecosystem, which later forms animals and humans," Dr Brocks said.
In addition, Dr. Amber Jarrrett - co-author of the study also shared: "We realized we had a great discovery . The frozen earth for 50 million years is the key to the complex development of life. like nowadays".
The frozen earth is the key.
