You're talking about a microevolution type of study. Each organism under each condition will be different. I don't have numbers off hand. Do a PubMed search on microevolution and bacteria, salmon, guppies, e coli or look for Genetics symposium or the Microevolution: rate, pattern, process by Hendry and Kinnison
Essentially sit and watch, count the number of changes, and how many live or die. Repeat.
1. What is the difference between a fact and a theory? Does controversy over the mechanisms of evolution reduce the believability of facts? A fact is something that can be directly observed. A theory is a statement of the natural law(s) that have caused things that we can observe. Thus, change in the characteristics of species or the types of species on Earth is a fact-- we can observe this. The Theory of Evolution by Natural Selection provides a mechanism for this change-- natural selection acting on variation within species. (I will also teach you how to observe natural selection, that is, differential survival or reproduction of different phenotypes, which will show you that natural selection is a fact too). In my opinion, understanding the mechanism is not necessary for accepting an observation as fact. |
