Why do I always choose to jump back in at the ends of semesters? Me thinks I like to torture myself! -I'll keep this quick (and David, please note that I'll get to your post as soon as possible. -> 
> Finally, once more, please give us your definition of Natural Selection.-The way I understand it: "Evolution by natural selection."-Natural selection is a function that takes two inputs, a group of genetically compatible organisms, as well as changes in environment, and its output is changes in frequencies of certain alleles within that group of organisms, where the alleles can be traced back to the changes in environment. -In the crude case, it works by simply killing those that lack certain traits. (Plague.) In the more nuanced cases it provides small statistical advantages to sub-populations within a given group. -Central to my definition is the presence of both organisms and environmental events. (Catastrophic events such as asteroids are just the easiest way to envision it.) To me, I consider a species entering a new environment as an environmental event as well. -I'm not conflating asteroid events with natural selection dhw, I'm stating that without a changed environment, there is NO evolution. The central point to "Natural Selection" is that changes we see in the fossil record happened by the challenge/response relationship between organisms and their environment. -Refuting it, is simple: demonstrate speciation without a corresponding environmental change, and without human intervention.

\"It is, brahmin, because of attachment to views, adherence to views, fixation on views, addiction to views, obsession with views, holding firmly to views that ascetics fight with ascetics.\"
