Cladogenesis is the term used to describe the branching off of new taxa. These branches — or clades — are based on several criteria which make the descendants along a particular branch different from their ancestors and from related taxa on other branches. Each new branch exhibits a combination of novel characteristics that are unique to that branch mixed with some "familial" characteristics which this branch shares with its evolutionary ancestors.

Entropy in Muffins: Why Evolution Does Not Violate the Second Law of Thermodynamics
Author(s):

Issue: 
5–6


Anti-evolutionists get a lot of mileage out of this chestnut because it uses scientific terms like “thermodynamics” and “entropy” to bolster their contention that evolution is unscientific. In fact, local increases in complexity/order are not only completely consistent with thermodynamics, but even expected by

Introduction

The origin of biological complexity is not yet fully explained, but several plausible naturalistic scenarios have been advanced to account for this complexity. “Intelligent design” (ID) advocates, however, contend that only the actions of an “intelligent agent” can generate the information content and complexity observed in biological systems.

Evolution and the Origin of Races

by Eugenie C. Scott

The movement called "scientific creationism" promotes the idea that a literal interpretation of the book of Genesis is scientifically demonstrable. Several organizations are attempting to have this view taught in American public school science classrooms. Rather than dealing with the general positions of the scientific creationists, I consider in this brochure some parts of the scientific creationist position dealing with the human fossil record and racial origins.
