Claim CB910:

No new species have been observed.


Morris, Henry M., 1986. The vanishing case for evolution. Impact 156 (Jun.).


  1. New species have arisen in historical times. For example:

  2. Incipient speciation, where two subspecies interbreed rarely or with only little success, is common. Here are just a few examples:

  3. Ring species show the process of speciation in action. In ring species, the species is distributed more or less in a line, such as around the base of a mountain range. Each population is able to breed with its neighboring population, but the populations at the two ends are not able to interbreed. (In a true ring species, those two end populations are adjacent to each other, completing the ring.) Examples of ring species are

  4. Evidence of speciation occurs in the form of organisms that exist only in environments that did not exist a few hundreds or thousands of years ago. For example:
    There is further evidence that speciation can be caused by infection with a symbiont. A Wolbachia bacterium infects and causes postmating reproductive isolation between the wasps Nasonia vitripennis and N. giraulti (Bordenstein and Werren 1997).

  5. Some young-earth creationists claim that speciation is essential to explain Noah's ark. The ark was not roomy enough to carry and care for all species, so speciation is invoked to explain how the much fewer "kinds" aboard the ark became the diversity we see today. Also, some species have special needs that could not have been met during the flood (e.g., fish requiring fresh water). Creationists assume that they evolved from other, more tolerant organisms since the Flood. (Woodmorappe 1996)
