Beneath the ocean’s surface, underneath sludge, ancient bacteria and mud, researchers have found what is said to be the slowest evolution that has ever been reported. These deep sea creatures have been alive for the past 2.3 billion years, and they might not have changed in the slightest. While others are battling over natural selection and mutating, these creatures have been at the bottom of the ocean, just kind of doing the same thing.
They appear to be in web like clusters, and they first appeared in some fossilised mud that was found in Australia. Darwin’s theory stated that species evolve through natural selection because of the response to environmental change. This can include access to water or air, competition and even new predators. If the environment doesn’t change, and there are no new predators, then the organism should actually stay the same because there are no reasons for it to evolve or to develop.
These microorganisms are very well adapted to their environments. Many people would think that this disproves Darwin’s theory; however it is quite the opposite. If the organisms were in an environment that didn’t change at all, yet they still continued to evolve, then this would disprove Darwin’s theory. As the environment and the organism have stayed the same, this breaks new ground on his already proven theory.
It is also said that this bacteria was completely isolated from any occurrences that might have happened, including meteor impacts and earthquakes. After billions of years, it seems that they never needed to change their DNA, and so they haven’t, making them a natural phenomenon in the eyes of scientists across the world.
I wonder what else is down there?
