'Binary' enzyme created by TSRI scientists demonstrates Darwinian evolution at its simplest
Two scientists at The Scripps Research Institute (TSRI), Research Associate John S. Reader, D.Phil, and Professor Gerald F. Joyce, M.D., Ph.D., both of the institute's Department of Molecular Biology, have succeeded in creating an enzyme based on a "binary" genetic code--one containing only two different subunits. ... ...This research, described in the latest issue of the journal Nature, demonstr...New cellular evolution theory rejects Darwinian assumptions
CHAMPAIGN, Ill. Life did not begin with one primordial cell. Instead, there were initially at least three simple types of loosely constructed cellular organizations. They swam in a pool of genes, evolving in a communal way that aided one another in bootstrapping into the three distinct types of cells by sharing their evolutionary inventions....... The driving force in evolving cellular life on....ITHACA, N.Y. -- Chemical signals at the most critical moment for new life in mammals -- when sperm meets egg and attempts fertilization -- evolve rapidly in a process driven by positive Darwinian selection, according to a Cornell University study. . , demonstrate for the fir.... WEST LAFAYETTE, Ind. -- Chemical engineers at Purdue University have.developed and demonstrated how a computerized system that mimics evolution can.discover new gasoline additives for better engine performance.. .
