scientists conference" was opened in the Beijing International Convention
Center. The conference was jointly sponsored by the American Chinese Biological
Scientists Association (SCBA), CAS, etc., with the theme of "Science
_ for a better life".
Nearly 2,000 scholars and specialists attended the

bio-technological sector including five Nobel prize winners. The topics
of discussion included the development of biotechnology and science to
which people show special concern, as well as the contagious disease such

Chinese Fossil Discovery Pushes Back the Bilaterian Animals 40-55 Million Years Before Cambrian Explosion
Over 99% modern animals are composed of members
of the evolutionary lineage bilaterians. The bilaterians had been highly
diverse and elaborated in Early Cambrian time, implying that they have
a long and complex Precambrian evolutionary history. The early evolutionary
history of bilaterian animals however, has remained a great puzzle.
The animal lived in green house event immediately
after the snowball earth. Chen and his collaborators named it as Vernanimalcula,
which implies small spring animal following the winter of snowball earth,
with its specific name honored to the fossil locality, Guizhou. This important
discovery was issued by "Science" magazine separately in June
3 through Internet and July 3 by a research article.
