What mechanism is in place to stop small changes from accumulating over many generations?

i think you are asking the wrong question.

It has never been observed that a bacteria evolved into something else than a bacteria. That is EMPIRICAL evidence that it simply does NOT happen.

You cannot logically get from "it has never been observed" to "it simply does NOT happen".

That is lazy, incorrect, fallacious thinking.

Hudge amount? Tongue

Care to address the concern that entropy expressed in information theory may be congruent to that expressed in thermodynamics? Considering that Earth is an open system an increase in information would thus be expected. Consider

that is one of most absurdly ignorant comments ever posted on TTA. Of course no one has ever "observed" that. Just how stupid are you ?

Family level phylogenies reveal modes of macroevolution in RNA viruses

Stupid idiot didn't even READ the studies.
Abstracts linked above : (these are NOT helping him .... he is so stupid and actually unversed in the subject, he doesn't even get why these studies do harm to his case)
"
Terrestrial biodiversity is dominated by plants and the herbivores that consume them, and they are one of the major conduits of energy flow up to higher trophic levels. Here, we address the processes that have generated the spectacular diversity of flowering plants (>300,000 species) and insect herbivores (likely >1 million species). Long-standing macroevolutionary hypotheses have postulated that reciprocal evolution of adaptations and subsequent bursts of speciation have given rise to much of this biodiversity. We critically evaluate various predictions based on this coevolutionary theory. Phylogenetic reconstruction of ancestral states has revealed evidence for escalation in the potency or variety of plant lineages' chemical defenses; however, escalation of defense has been moderated by tradeoffs and alternative strategies (e.g., tolerance or defense by biotic agents). There is still surprisingly scant evidence that novel defense traits reduce herbivory and that such evolutionary novelty spurs diversification. Consistent with the coevolutionary hypothesis, there is some evidence that diversification of herbivores has lagged behind, but has nevertheless been temporally correlated with that of their host-plant clades, indicating colonization and radiation of insects on diversifying plants. However, there is still limited support for the role of host-plant shifts in insect diversification. Finally, a frontier area of research, and a general conclusion of our review, is that community ecology and the long-term evolutionary history of plant and insect diversification are inexorably intertwined."

"Despite advances in understanding the patterns and processes of microevolution in RNA viruses, little is known about the determinants of viral diversification at the macroevolutionary scale. In particular, the processes by which viral lineages assigned as different “species” are generated remain largely uncharacterized. To address this issue, we use a robust phylogenetic approach to analyze patterns of lineage diversification in five representative families of RNA viruses. We ask whether the process of lineage diversification primarily occurs when viruses infect new host species, either through cross-species transmission or codivergence, and which are defined here as analogous to allopatric speciation in animals, or by acquiring new niches within the same host species, analogous to sympatric speciation. By mapping probable primary host species onto family level viral phylogenies, we reveal a strong clustering among viral lineages that infect groups of closely related host species. Although this is consistent with lineage diversification within individual hosts, we argue that this pattern more likely represents strong biases in our knowledge of viral biodiversity, because we also find that better-sampled human viruses rarely cluster together. Hence, although closely related viruses tend to infect related host species, it is unlikely that they often infect the same host species, such that evolutionary constraints hinder lineage diversification within individual host species. We conclude that the colonization of new but related host species may represent the principle mode of macroevolution in RNA viruses."

How the fuck did you manage to fuck up the quote function so much as to have Chas saying that shit? Who's on drugs? Laugh out load

The sun.

Entropy must increase assuming that the system in question is closed - that is, there is no more energy coming in from outside. Earth gets quite a lot of energy from the sun. It is not a closed system.

I know it's been said before, but I feel it needs to be repeated, and noted that it is not hyperbole: this is middle school level information. In fact, I learned about this in elementary school, albeit in an advanced placement science program.
