Scientists reverse evolution
... The ability to reconstruct an ancient gene from descendant
genes also raises the possibility of a new type of gene therapy, in which a portion of a related gene could be inserted into a disease-causing mutant gene to restore its normal function and cure the disease, Capecchi and Tvrdik say. Genes that Di...

...acetate-producing species appears to be the direct descendant
of one of the earliest true microbes. "We know that this bug is very ancient indeed," Ferry told the Penn State Astrobiology Research Center's annual meeting earlier this week. "There is strong phylogenetic evidence that acetate kinase is a very anci...
