Matt: 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.

Just like we can point to the fact that the sun will rise tommorrow. ->We can see that the most successful biomass on Earth are bacteria. Why bother with multicelualarity if so successful? -This here is a problem for you because you desire to see a purpose for everything. Romansh's paper demonstrates that multicellularity *just happened.* ->And we still don't know how speciation is created, so your demonstration is wanting. Certain weird developments like mammals taking to water look like deliberate changes with n o obvious cause. -Mammals add intelligence to the scenario which complicates things. A mammal can roam far beyond its range and be faced with an intelligence problem of finding unfamiliar food. Intelligence is a factor of evolution too, which has been a strong backdrop for my posts here. And if I recall, speciation happens when a subgroup can no longer create viable offspring with its parent group. -Here's a complete treatise on the entire subject: http://www.talkorigins.org/faqs/faq-speciation.html->My point is that we still do not know enough to know why we see evolutionary changes in form resulting from descrete jumps, not tiny increments. Most Darwin scientists seem to now recognize it is a major problem for the theory.-Could you do better to explain what you mean by discrete jumps, because every time you bring this up, you always make me think you're talking about the fossil record, and the canned explanation "we don't have a fossil for every form in-between!"

\"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.\"
