Researchers say that they found ancient communities of bacteria in the sea floor that haven’t changed practically for 2.3 billion years.
According to the Charles Darwin’s theory of evolution, these microscopic organisms are related to the “extreme evolutionary stasis”.
Team of researchers collected fossilized sulfur bacteria, these organisms are small in size and it’s difficult to see with the unaided eye, that are 1.8 billion years old compare with the bacteria lived in the same region of 2.3 billion years ago. Both sets of ancient bacteria that are identical from modern sulfur bacteria found off the coast of Chile.
At UCLA College, Professor J. William Schopf said “It seems surprising that life has unchanged for more than 2 billion years — nearly half the history of the Earth.”
Schopf said “When the environment surface changes all the time, biology also changes,” and also he added “There is no turning of sediments, things don’t get motivated up, absence of oxygen at all — they get no time signal, there is no change.”
Darwin’s theory of evolution focused on species that they had changed over time than on those that hadn’t.
Schopf says, microbe develop in the response of changing environment and linked to a lack of change in their environment.
