Biologists recently discovered how tomcod…a smaller variation of cod…have thrived in the polluted waters of the Hudson River. The reports on their research are soaked in evolutionary jargon, but the data they dredged from the DNA of these and neighboring tomcod demonstrate that evolution had nothing to do with the fish's unexpected proliferation in poisoned waters.

Bones were discovered in a cave in Germany's Neander Valley in the middle 1800s. Since then, many more "Neandertal" remains have been uncovered. The story has been told that they wore no clothes, had a very primitive culture, and hunted animals with clubs as they evolved from an ape-like to a man-like creature. But is this an accurate picture?

Just one genus of flowering plant, Veronica, includes over 450 different species. They share similarities with other flower genera, some of which have radially symmetrical flowers and others with bilaterally symmetrical flower petal arrangements. Could varieties that look so different have descended from the same flower stock?

Darwinian evolution asserts that a single original organism morphed over countless generations into the modern known life forms. Each species alive today would therefore represent the tip of its own "branch" on a gigantic imaginary tree of life, with the hypothetical ancestor of all life forms situated at the base of the trunk.

Unlike other creatures, humans can compose, record, and enjoy music. A new study has identified a brain chemical that provides pleasure when people listen to certain music. Where did this amazing ability come from?
