There are many mysteries pertaining to our habitat, nature, and evolution of natural species. Now after continuous research researchers have predicted that algal bloom can reveal the mystery about when animals first appeared on Earth. The Australian researchers have successfully determined when the animals were first seen on the planet and how it led to the developed of human life.
For the purpose of the study, the researchers studied the sedimentary rocks from central Australia to determine the origin of animals from the algal bloom which is present from past 650 million years. About 3 million years ago there were only the single cell organisms which existed and later on the multi cellular organisms evolved.
The formation of algal bloom has taken place about 650 million years ago due to the melting of snowball Earth and the freezing of equatorial regions which transformed everything into a watery planet. The melting of huge glaciers led to the algal bloom. This algal bloom then released all the nutrients into the river. The algal bloom then melted then flooded the oceans and replaced the microscopic bacterias. This marked the beginning of ecosystems due to which multicellular organisms like animals were formed.
While examining the sedimentary rocks the researchers crushed them in powder form and determined whether there was a presence of ancient organisms which resolved the mystery behind the rise of complex organisms. Due to favorable temperature and atmospheric conditions, there was huge algal bloom. These algal blooms provided the necessary energy which was needed for the survival of other organisms.
Till now the first appearance of animals and other life forms was a mystery and a topic of debate for many researchers. Many people believed that there are some internal or environmental factors which have led to the origin of animal life. The detailed study and its findings have been published in the journal Nature.
