Giving weight to Darwin’s theory of ’living fossils’
When Charles #Darwin invented the term ’living fossils’ in 1859, he was thinking of living species that look just like their ancestors of millions of years ago. His explanation was they occupied small parts of the world, escaping competition, and therefore did not change.
“Darwin’s wasn’t a testable definition. By using modern numerical methods we have now shown that living fossils should show unusually slow rates of evolution compared to relatives,” said co-author, Dr Tom Stubbs.
