PE is a different theory to explain evolution. <BR/><BR/>Your summation of PE is quite nice, ZP. It's definitely not a case of needing to accept one theory or the other--the two complement one another.utenzihttps://www.blogger.com/profile/15988445461413550750noreply@blogger.comtag:blogger.com,1999:blog-16623883.post-68145168337818668862007-02-15T11:47:00.000-05:002007-02-15T11:47:00.000-05:00Also, as I understand it, punctuated equilibrium i...Also, as I understand it, punctuated equilibrium is to Darwinian evolution, as General Relativity is to Newton's Law of Universal Gravitation. It's a refinement of the original theory to account for additional information.zandperlhttps://www.blogger.com/profile/01700239961953729095noreply@blogger.comtag:blogger.com,1999:blog-16623883.post-56395719324552325422007-02-15T11:45:00.000-05:002007-02-15T11:45:00.000-05:00As I understand PE, it is a modification of Darwin...As I understand PE, it is a modification of Darwinian evolution that is more accepted by biologists today. DE says that natural selection takes place over millenia and is a very slow process. PE says that this is the case most of the time, except when some dramatic event occurs that rapidly changes the environment of a species, and then evolution happens explosively. <BR/><BR/>PE does not deny natural selection, just specifices the circumstances under which it is more likely to happen quickly vs. slowly. It explains the apparent "gaps" in the fossil record, where species appear to be "created" overnight, as in reality they evolved too rapidly (on a geologic time scale) to show in the fossil record due to some catastrophic event, but still through a process of gradual natural selection. <BR/><BR/>If my understanding is incorrect, do please correct me.zandperlhttps://www.blogger.com/profile/01700239961953729095noreply@blogger.comtag:blogger.com,1999:blog-16623883.post-63401565773284406282007-02-15T11:37:00.000-05:002007-02-15T11:37:00.000-05:00Punctuated equlibrium has supplanted natural selec...Punctuated equlibrium has supplanted natural selection? You might want to do a wee bit of research on that one, ZP! You're going to end up in the ID camp yet.<BR/><BR/>There is no one theory of evolution that works in all situations. That's reasonable because all sorts of situations exist to push speciation. PE works great during situations of rapid change but Darwin's theory holds well for gradual change.utenzihttps://www.blogger.com/profile/15988445461413550750noreply@blogger.com
