Naked foraminiferans revealed
Article Abstract:
Ribosomal DNA and actin gene sequences were obtained from Reticulomyxa filosa, a freshwater amoeba, lacking a shell but possessing pseudopodia, similar to those of foraminiferans. Phylogenetic analyses shows that R.filosa is actually a foraminiferan, suggesting that some foraminiferans may lack a shell and live in freshwater. It is predicted that naked foraminiferans may still live in marine environments.

Evolution all at sea
Article Abstract:
Plankton are widely dispersed throughout the world's oceans from pole to pole. New evidence of genetic similarity between species from Arctic and Antarctic suggests that they must exchange populations regularly notwithstanding the different environment of tropical seas inbetween.

The missing link in Ginkgo evolution
Article Abstract:
The maidenhair tree, or Ginkgo, known to exist since the Jurassic period, is still not changed. The reasons behind this phenomena are discussed.
