Have Milky Way’s Cycles Influenced Earth’s Biological History?
The following article was posted yesterday on The Daily Galaxy: Early last year, research revealed that the rise and fall of species on Earth seems to be driven by the undulating motions of our solar system as it travels through the Milky Way. Some scientists believe that this cosmic force may offer the answer to some of the biggest questions in our Earth’s biological history. The University of California, Berkeley found that marine fossil records show that biodiversity increases and decreases based on a 62-million-year cycle. At least two of the Earth’s great mass extinctions—the Permian extinction 250 million years ago and the Ordovician extinction about 450 million years ago—correspond with peaks of this cycle, which can’t be explained by evolutionary theory.
