Litter taxes do not provide a disincentive to litter. Since they are passed on to consumers in the price of goods, citizens don't know they are paying or why. Most litter taxes are collected three times: once from the manufacturer, again from the wholesaler, and once from the retailer.

Punctuated equilibrium can be accommodated within the classical neo-Darwinian synthesis as an end-member of the spectrum of possible evolutionary events that lead to the appearance of new species. But it's not the only possible mode of speciation: it is one possible mode. There's no intrinsic reason that evolutionary change should occur only in small populations, and there's no evidence that populations that have undergone marked evolutionary change are any smaller than those that are stable.
