[ QUOTE ]
I wouldn't know where to begin reading from your list, but can you sum up how, for example, scientists have proven macro-evolution? It seems counterintuitive that someone could observe such a process, which, according to theory I was presented, takes place over thousands, hundreds of thousands, and millions of years. [/ QUOTE ] Yes, it usually takes a long time. Current theories indicate that it generally takes about 3 million years, on average. Futuyma, D. (1998) Evolutionary Biology. Third edition. But certain organisms have very brief lifecycles, and for them, speciation has been directly observed (in nature and in labs): fruit flies, houseflies, flour beetles, worms, mosquitos, green algae, bacteria, and many more. In fact, we've even directly observed speciation in mammals. Six instances of speciation have occurred in house mice within the past 500 years. Britton-Davidian, J., J. Catalan, et al. (2000) "Rapid chromosomal evolution in island mice." Nature 403: 158. See the "Observed Instances of Speciation" FAQ from Talk.Origins for more on this subject. |
