New Findings Confirm Darwin's Theory: Evolution Not Random

ScienceDaily (Jan. 20, 2008) — According to Darwin’s theory of evolution, individuals in a species pass successful traits onto their offspring through a process called “deterministic inheritance.” Over multiple generations, advantageous developmental trends – such as the lengthening of the giraffe’s neck – occur.

An opposing theory says evolution takes place through randomly inherited and not necessarily advantageous changes. Using the giraffe example, there would not be a common neck-lengthening trend; some would develop long necks, while others would develop short ones.

Now, the findings of an international team of biologists demonstrate that evolution is not a random process, but rather occurs through the natural selection of successful traits. The collaborative study by researchers at the Technion-Israel Institute of Technology in Israel, the U.S, France and Germany is published in the November 2007 issue of Current Biology (vol. 17, pp. 1925-1937).
