A new study led by Adelaide researchers has estimated, for the first time, the rates of evolution during the 'Cambrian explosion' when most modern animal groups appeared between 540 and 520 million years ago. The findings, published online today in the journal Current biology, resolve "Darwin's dilemma": the sudden appearance of a plethora of modern animal groups in the fossil record during the early Cambrian period.

The traditional studies sought explanations for how the body plans of the three dozen or so major animal groups most likely evolved, but molecular data provide strong evidence about genealogical relationships without yielding Top; Send Feedback A key assumption that biologists have relied on widely over the past quarter-century in studying the evolution of protein molecules is "highly questionable," according to an article published in the November issue of
