Magnetic maps in animals: A theory comes of age?

Article Abstract:

Animals can use spatial gradients in the Earth's magnetic field in order to help determine geographic location as per the magnetic map hypothesis. More important advances are made in conducting direct tests of the magnetic map hypothesis by exposing experienced migrants to specific geomagnetic values that represent simulated displacements.

Evolutionary biology: Puzzle solving or paradigm shifting?

Article Abstract:

Application of philosopher of science Thomas Kuhn's scientific activity phrases, "normal" science and paradigm shifts with regard to biology is discussed. It is felt that evolutionary biology would keep defying Kuhn's model or paradigm shifts that would clearly distinguish the modus operandi of physics from that of biology.
