The recent discovery in China of an unusually intact and ancient fossil
fish, the distant ancestor of about 99.7 percent of today's living
vertebrates including human beings, has provoked a rash of new fieldwork and
a fresh look at the early evolution of vertebrates.

The fish, called Guiyu and described in detail in today's (May 26) journal
Nature by Zhu Min and his colleagues from the Institute of Vertebrate
Paleontology and Paleoanthropology (IVPP) under the China Academy of
Sciences, dates back to the Silurian period, more than 418 million years ago

...

The discovery of Guiyu in Yunnan province has added to the increasing
evidence that some of the key steps in early vertebrate evolution took place
in southern China about 400-450 million years ago, at a time when that
region was a small separate island continent near the equator, according to
Swedish paleontologist Per Ahlberg from Uppsala University.

...

Zhu says it is expected the discovery of Guiyu will revitalize the "long
stagnant research tracing the very basal root of vertebrates". "More
surprises are to be expected."
