About Science Frontiers

Science Frontiers is the bimonthly newsletter providing digests of reports that describe scientific anomalies; that is, those observations and facts that challenge prevailing scientific paradigms. Over 2000 Science Frontiers digests have been published since 1976.

These 2,000+ digests represent only the tip of the proverbial iceberg. The Sourcebook Project, which publishes Science Frontiers, also publishes the Catalog of Anomalies, which delves far more deeply into anomalistics and now extends to sixteen volumes, and covers dozens of disciplines.

Over 14,000 volumes of science journals, including all issues of Nature and Science have been examined for reports on anomalies. In this context, the newsletter Science Frontiers is the appetizer and the Catalog of Anomalies is the main course.


Subscriptions

... dismisses this, as the creationists do, as merely an example of variation within a species. We now quote the lead sentences from her discussions of the next two candidates: "An incipient neospecies of Drosophila may have developed in Theodosius Dobzhansky's laboratory sometime between 1958 and 1963 in a strain of D. paulistorum...." "A probable instance of a naturally emerging plant species was discovered on both sides of Highway 205 at a single locality 25.5 miles south of Burns, Harney County, Oregon...." We have inserted underlining beneath the two words that greatly weaken the paper. In short, the biologists are not really sure that speciation occurred in these two cases. The reasons for doubt are also presented. The paper concludes with a discussion of allopolyploidy in plants, in which the chromosomes of a sterile hybrid are doubled, giving rise to a fertile variety. Allopolyploidy has been observed in primroses, tobacco, cotton, and other plants. And that's it; two questionable examples and allopolyploidy.
