These ancient seafloor microbes woke up after over 100 million years

Even after 100 million years buried in the seafloor, some microbes can wake up. And they’re hungry.

An analysis of seafloor sediments dating from 13 million to nearly 102 million years ago found that nearly all of the microbes in the sediments were only dormant, not dead. When given food, even the most ancient microbes revived themselves and multiplied, researchers report July 28 in Nature Communications.

Scientists have pondered how long energy-starved microbes might survive within the seafloor. That such ancient microbes can still be metabolically active, the researchers say, just goes to show that scientists are still fathoming the most extreme limits to life on Earth.

re: These ancient seafloor microbes woke up after over 100 million years
For me it’s easier to think of the microbes continuing the chemical reactions that define their life than to see them as “waking up” or being “hungry.” We tend to anthropomorphize everything.

Life is merely an extremely complex chain reaction that continues until necessary chemicals run out or until the process shuts itself down via established mechanisms that control the chain reaction’s length of time.

How long do we have before the whole ocean turns red as blood?
