Exciting evolution discoveries

Startling plant discovery presents problems for evolution:

...a paper in Nature describes a plant that can fix its own mutations, apparently without using DNA as a template.4 The plant, Arabidopsis thaliana, is able to revert from a homozygous recessive mutant form, known as Hothead, to a heterozygous normal form by altering the DNA base sequence on one of the homologous recessive genes. Such a mechanism allows a “revert to saved” function not unlike that in Microsoft Office®. The plant is able to revert to a previous copy of the gene just as an author can revert to a previously saved copy of a document if undesirable changes were made. Another parallel is the “Edit-undo” function. Both of these significantly benefit computer users, however it is stunning to see such a phenomenon in living things.

(to finish reading). Also, they have an article on the recent amazing find of soft tisse in dinosaur bones:

Not only have more blood cells been found, but also soft, fibrous tissue, and complete blood vessels. The fact that this really is unfossilized soft tissue from a dinosaur is in this instance so obvious to the naked eye that any scepticism directed at the previous discovery is completely “history”... It beggars belief that elastic tissue like this could have lasted for 65 million years.

They have pictures, which I hadn't seen before.
