Convergence vs. natural selection Summary of problems: There is nothing mysterious about convergence. Species facing similar selective pressures would be expected to be similar in certain ways. There is no reference to any particular scientist who would support the claims EE advances, but it is an argument commonly advanced in the creationist literature. Full discussion: Explore Evolution says the following about convergence: Neo-Darwinian biologists use the term "convergence" or "homoplasy" to describe similar structures that are not due to common ancestry but which are found in different types of organisms. They call these features convergent because they think that the evolutionary process has come together (converged) on the same structure two or more times in creatures that exist on very different branches of the Tree of Life. Convergence is a deeply intriguing mystery, given how complex some of the structures are. Some scientists are skeptical that an undirected process like natural selection and mutation would have stumbled upon the same complex structure many different times. EE , p. 48 No citation is given to the scientists who are supposedly skeptical about the ability of natural selection to explain convergence. Indeed, it's difficult to imagine how anyone who thinks a structure could evolve in one lineage in response to a set of selective pressures would be
