This study published in Nature on the 1st December
2021has evolution and millions ofyears.Without them, it would not be called a study,
But evolution supposes that
millions of years were needed to get from a what they call a simple cell to the
sophisticated people of today’s world.
Here’s what science daily says:
“Coccolithophores are
microscopic algae that form tiny limestone plates, called coccoliths, around
their single cells. The shape and size of coccoliths varies according to the
species. After their death, coccolithophores sink to the bottom of the ocean
and their coccoliths accumulate in sediments, which faithfully record the
detailed evolution of these organisms over geological time.
They underwent cycles of higher and lower diversity in size and shape, with rhythms of 100 and 400 thousand years. They also propose a cause: the more or less circular shape of Earth's orbit around the Sun, which (according to evolution) varies at the same rhythms. “
They may also explain hitherto mysterious climate variations in past warm periods.
Yes, putting climate change in an evolution research.
